IMPORTANT SAFETY CONSIDERATIONS
It is very important for the user to consider the possible adverse
effects of power, wiring, component, sensor, or software failures in
designing anytype of control or monitoring system. This is
especially important where economic property loss or human life is
involved. It is important that the user employ satisfactory overall
system design. It is agreed between the Buyer and Acromag, that
this is the Buyer's responsibility.
1.0 GENERAL INFORMATION
The Industrial I/O Pack (IP) Series IP445 module is a bus
isolated 32-channel output module. The IP445 provides control for
32 solid state relays which are bipolar and may be used to switch
positive or negative voltages. Four units may be mounted on a
carrier board to provide up to 128 channels of output control in a
single system slot. The IP445 offers a variety of features which
makeit an ideal choice for many industrial and scientific applications
as described below.
MODEL OPERATING TEMPERATURE RANGE
IP445 0 to +70°C
IP445E -40 to +85°C
KEY IP445 FEATURES
•High Channel Count - Individual control of up to 32 (SPST-
NO) bipolar Solid State Relays (SSR’s) is provided. Four units
mounted on a carrier board provide 128 channels in a single
system slot.
•High-Speed/0 Wait States - No wait states are required for all
read/write cycles (all cycles complete in 250nS.) and hold
states are supported.
•Optically Isolated - Individual bipolar SSR’s provide isolation.
The IP445 contains four groups (ports) of eight channels which
include separate port commons to ensure port to port isolation.
Individual ports are isolated from each other and from the IP
logic.
•Low-Side or High-Side Switch Configuration - Each group
of eight channels can be connected directly to positive or
negative supplies for high (hot) side switching. Alternatively,
each group of eight channels can be connected to common for
low side switching. Socketed pull-up resistors are provided for
low side switching applications.
•TTL Compatible - When configured as a low side switch will
sink 27mA at 0.4 volts. Sourcing is controlled by the installed
pull-up resistor.
•Power Up & System Reset is Fail-safe - For safety, the
outputs are turned OFF upon power-up and a system reset.
Thus, the SSR’s will be disabled after a power-up or system
reset.
•Wide Range Bipolar Voltage Outputs - Outputs are rated
from 0 to ±60 volts. The bipolar solid state relays allow both
AC and DC switching.
•Output Readback Function - Readback buffers are provided
that allow the output channel registers to be read back.
•Loopback Compatible with IP440 Digital Input Module -
The P2 field I/O pin assignments of the IP445 output module
correspond with those of the Acromag IP440 Bus Isolated
Input module. This provides direct closed-loop monitoring of
the output states.

footprint. Four units mounted on a carrier board provide up to
128 isolated output points in a single system slot. Both
VMEbus and ISA bus (PC/AT) carriers are supported.
•Local ID - Each IP module has its own 8-bit ID signature which
can be read via access to the ID space.
•8-bit I/O - Port register Read/Write is performed through 8 or
16-bit data transfer cycles in the IP module I/O space.
•High Speed with No Wait States - Access times for all data
transfer cycles are described in terms of "wait" states - 0 wait
states are required for all read and write operations of this
model. See Specification section for detailed information.
SIGNAL INTERFACE PRODUCTS
(See Appendix for more information on compatible products)
This IP module will mate directly to any industry standard IP
carrier board (including Acromag AVME9630/9660 3U/6U non-
intelligent VMEbus carrier boards). Additionally, Acromag’s
APC8600 ISA bus (PC/AT) carrier board is also supported. A wide
range of other Acromag IP modules are also available to serve your
signal conditioning and interface needs.
The following cables and termination panels are also available.
Consult your carrier board documentation for the correct interface
product part numbers to ensure compatibility with your carrier board.
Cables
Model 5025-551-X (Shielded Cable), or Model 5025-550-X
(Non-Shielded Cable): A Flat 50-pin cable with female
connectors at both ends for connecting AVME9630/9660, or
other compatible carrier boards, to Model 5025-552 termination
panels. The “-X” suffix of the model number is used to indicate
the length in feet.
The unshielded cable is recommended for digital I/O, while the
shielded cable is recommended for optimum performance with
precision analog I/O applications.
Model 5029-900 APC8600 High-Density Cable: A 36-inch long
interface cable that mates the high-density (25mil pitch) 50-pin
I/O connectors of the APC8600 ISA bus carrier board, to the
high-density connectors on the APC8600 Termination Panel
(described below).
Termination Panels:
Model 5025-552: A DIN-rail mountable panel that provides 50
screw terminals for universal field I/O termination. Connects to
Acromag AVME9630/9660, or other compatible carrier boards,
via flat 50-pin ribbon cable (Model 5025-550-X or 5025-551-X).
Model 5029-910 APC8600 High-Density-to-Screw-Terminal
Termination Panel: This panel converts the high-density ribbon-
cable connectors coming from the APC8600 carrier board
(Acromag cable Model 5029-900) to screw terminals, for direct-
wired interfaces.
Transition Module:
Model TRANS-GP: This module repeats field I/O connections
of IP modules A through D for rear exit from a VMEbus card
cage. It is available for use in card cages which provide rear exit
for I/O connections via transition modules (transition modules
can only be used in card cages specifically designed for them).
It is a double-height (6U), single-slot module with front panel
hardware adhering to the VMEbus mechanical dimensions,
except for shorter printed circuit board depth. It connects to
Acromag Termination Panel 5025-552 from the rear of the card
cage, and to AVME9630/9660 boards within the card cage, via
flat 50-pin ribbon cable (cable Model 5025-550 or 5025-551).
INDUSTRIAL I/O PACK SOFTWARE LIBRARY
Acromag provides an Industrial I/O Pack Software Library
diskette (Model IPSW-LIB-M03, MSDOS format) to simplify
communication with the board. Example software functions are
provided for both VMEbus and ISA bus (PC/AT) applications. All
functions are written in the “C” programming language and can be
linked to your application. For more details, refer to the
“README.TXT” file in the root directory on the diskette and the
“INFO445.TXT” file in the appropriate “IP445” subdirectory off of
“\VMEIP” or “\PCIP”, according to your carrier.
2.0 PREPARATION FOR USE
UNPACKING AND INSPECTION
Upon receipt of this product, Inspect the shipping carton for
evidence of mishandling during transit. If the shipping carton is
badly damaged or water stained, request that the carrier's agent be
present when the carton is opened. If the carrier's agent is absent
when the carton is opened and the contents of the carton are
damaged, keep the carton and packing material for the agent's
inspection.
For repairs to a product damaged in shipment, refer to the
Acromag Service Policy to obtain return instructions. It is suggested
that salvageable shipping cartons and packing material be saved for
future use in the event the product must be shipped.

CARD CAGE CONSIDERATIONS
Refer to the specifications for loading and power requirements.
Be sure that the system power supplies are able to accommodate
the power requirements of the carrier board, plus the installed IP
modules, within the voltage tolerances specified.
IMPORTANT: Adequate air circulation must be provided to prevent
a temperature rise above the maximum operating temperature.
The dense packing of the IP modules to the carrier board
restricts air flow within the card cage and is cause for concern.
Adequate air circulation must be provided to prevent a temperature
rise above the maximum operating temperature and to prolong the
life of the electronics. If the installation is in an industrial
environment and the board is exposed toenvironmental air, careful
consideration should be given to air-filtering.
BOARD CONFIGURATION
Power should be removed from the board when installing IP
modules, cables, termination panels, and field wiring. Refer to
Mechanical Assembly Drawing 4501-434 and your IP module
documentation for configuration and assembly instructions. Module
IP445 digital output boards have no hardware jumpers or switches to
configure. Software configurable control registers are provided for
control of all modes of operation. Refer to section 3 for
programming details.
This module is built with socketed output pull-up resistors
installed. These may be used when the SSR’s are applied as low
side switches. Resistor values maybe changed if needed, and the
resistors may be removed for high side switching (see IP445
Resistor Location Drawing 4501-606).
CONNECTORS
IP Field I/O Connector (P2)
P2 provides the field I/O interface connections for mating IP
modules to the carrier board. P2 is a 50-pin female receptacle
header (AMP 173279-3 or equivalent) which mates to the male
connector of the carrier board (AMP 173280-3 or equivalent). This
provides excellent connection integrity and utilizes gold-plating in the
mating area. Threaded metric M2 screws and spacers are supplied
with the module to provide additional stabilityfor harsh environments
(seeMechanical Assembly Drawing 4501-434). The field and logic
side connectors are keyed to avoid incorrect assembly.
P2 pin assignments are unique to each IP model (see Table 2.1)
and normally correspond to the pin numbers of the field I/O interface
connector on the carrier board (you should verify this for your carrier
board).

The output channels of this module are divided into four ports of
eight channels each. All channels within a port share a common
signal connection with each other. Isolation is provided between the
ports and the IP logic. In addition, bus isolation is provided between
ports.
P2 pin assignments are arranged to be compatible with similar
Acromag models. This model is directly loopback compatible with
the Acromag Model IP440 32-Channel Digital Input Board.
Likewise, pin assignments are identical to those of Acromag Model
IP405 40-Channel Digital Output Boards for channels 0-31, except
for the user supply connections. This model (remove socketed pull-
up resistors) may also interface with industry accepted I/O panels,
termination panels, and relay racks when used with the Acromag
Model 5025-655 I/O Adapter Card. However, relay racks are usually
isolated in which case it would probably be more efficient to use the
non-isolated IP405 module. Consult the factory for information on
these and other compatible products.
Refer to Drawing 4051-604 for example field output
connections. See Drawing 4501-603 for loopback connections to
Acromag Model IP440 Input Modules.
Note that the outputs of this module are bipolar, and may be
connected in any direction with respect to the port common.
Further, do not confuse port commons with signal ground. For the
IP445, port common only infers that this lead is connected common
to the 8 outputs of the port (a separate common for each port). The
port commons of the IP445 output module and IP440 input
module are normally not connected together for loopback
interconnection (see Drawing 4501-603).

Grounding and Noise Considerations
Output lines of the IP445 are optically isolated between the logic
and field output connections. Likewise, separate port commons
ensure port-to-port isolation. Consequently, the field I/O
connections are isolated from the carrier board and backplane, thus
minimizing the negative effects of ground bounce, impedance drops,
and switching transients. However, care should be taken in
designing installations to avoid inadvertentlycompromising isolation,
or creating ground loops which can cause noise pickup and reduce
overall system reliability.
IP Logic Interface Connector (P1)
P1 of the IP module provides the logic interface to the mating
connector on the carrier board. The pin assignments of P1 are
standard for all IP modules according to the Industrial I/O Pack
Specification (see Table 2.2). The IP Logic Interface connector is a
50-pin female receptacle header (AMP 173279-3 or equivalent)
which mates to the male connector of the carrier board (AMP
173280-3 or equivalent). This provides excellent connection integrity
and utilizes gold-plating in the mating area. Threaded metric M2
screws and spacers are supplied with the IP module to provide
additional stability for harsh environments (see Drawing 4501-434
for assembly details). Field and logic side connectors are keyed to
avoid incorrect assembly.

3.0 PROGRAMMING INFORMATION
IP IDENTIFICATION SPACE - (Read Only, 32 Odd-Byte
Addresses)
Each IP module contains identification (ID) information that
resides in the ID space per the IP module specification. This area of
memory contains 32 bytes of information at most. Both fixed and
variable information maybe present within the ID space. Fixed
information includes the "IPAC" identifier, model number, and
manufacturer's identification codes. Variable information includes
unique information required for the module. The IP445 ID
information does not contain any variable (e.g. unique calibration)
information. ID space bytes are addressed using only the odd
addresses in a 64 byte block (on the “Big Endian” VMEbus). Even
addresses are used on the “Little Endian” PC ISA bus. The IP445
ID space contents are shown in Table 3.1. Note that the base-
address for the IP module ID space (see your carrier board
instructions) must be added to the addresses shown to properly
access the ID space. Execution of an ID space read requires 0 wait
states.

I/O SPACE ADDRESS MAP
This board is addressable in the Industrial Pack I/O space to
control the 32 channels of digital output to the field.
The I/O space may be as large as 64, 16-bit words (128 bytes)
using address lines A1 to A6, but the IP445 uses only a portion of
this space. The I/O space address map for the IP445 is shown in
Table 3.2. Note that the base address for the IP module I/O space
(see your carrier board instructions) must be added to the addresses
shown to properly access the I/O space. Accesses may be
performed on an 8 or 16-bit basis but only D0-D7 are driven. D08-
D15 are not used but will normally read high due to pull-up resistors
on the carrier board.
The following table shows the memory map for the IP445. Data
is read and written to one of four groups (ports) as designated by the
address.

Notes (Table 3.2):
1. The IP will not respond to addresses that are "Not Used".
2. All Register accesses implement 0 wait state data transfers.
This memory map reflects byte accesses using the “Big Endian”
byte ordering format. Big Endian is the convention used in the
Motorola 68000 microprocessor family and is the VMEbus
convention. In Big Endian, the lower-order byte is stored at odd-byte
addresses. The Intel x86 family of microprocessors uses the
opposite convention, or “Little Endian” byte ordering. Little Endian
uses even-byte addresses to store the low-order byte. As such,
installation of this module on a PC carrier board will require the use
of the even address locations to access the lower 8 data bits while
on a VMEbus carrier use of odd address locations are required.

Write a zero to each channel’s position to turn the
corresponding SSR OFF. Write a one to each channel’s position to
turn the corresponding SSR ON.
Each output channel register can be conveniently read back for
verification purposes. For critical control applications, it is
recommended that outputs be directly fed back to an input point and
the input point monitored (loopback I/O). Acromag Model IP440 32-
channel isolated input modules can be used to implement loopback
output monitoring with this model (see Drawing 4501-603).
On power-up, hardware reset, or software reset, the ports are
reset to 0 forcing the outputs (SSR’s) to be OFF.
IP445 PROGRAMMING
Acromag provides you with the Industrial I/O Pack Software
Library diskette (Model IPSW-LIB-M03, MSDOS format) to make
communication with the board easy. Example software functions are
provided for both ISAbus (PC/AT) and VMEbus applications. All
functions are written in the “C” programming language and can be

4.0 THEORY OF OPERATION
This section contains information regarding the basic
functionality of the circuitry used on the IP445. Refer to the Block
Diagram shown in Drawing 4501-605 as you review this material.
LOGIC/POWER INTERFACE
The logic interface to the carrier board is made through
connector P1 (refer to Table 2.2). The P1 interface also provides
+5V power to the module. Note that data lines D08..D15, BS1*, the
DMA control, interrupt requests (INTREQ0∗and INTREQ1∗),
ERROR∗, STROBE∗and +/-12V power signals are not used.
A Field Programmable Gate-Array(FPGA) installed on theIP
Module provides an interface to the carrier board per IP Module
specification revision 0.7.1. The interface to the carrier board allows
complete control of all IP445 functions. This logic includes: address
decoding, I/O and ID read/write control circuitry, and ID space
implementation. With regard to throughput, 0 wait states are
required for read and write operations.
Address decoding of the six IP address signals A(1:6) is
implemented in the FPGA, in conjunction with the IP select signals,
to identify access to the IP module’s ID or I/O space. In addition, the
byte strobe BS0∗is decoded to identify a low byte data transfer.
OUTPUT PORTS
The field I/O interface to the carrier board is provided through
connector P2 (refer to Table 2.1). Individual Solid State Relays
(SSR’s) for each channel isolatethe field from the control logic for
the IP445. Channels are isolated from each other in groups of eight.
There are eight channels to a group or port. Because the output
lines of a single port share a common connection, individual outputs
are not isolated from each other within the same port. However,
separate port commons are provided to facilitate port-to-port
isolation.
32 Single Pole Single Throw - Normally Open (SPST-NO,
“1 Form A”) SSR outputs are controlled bythis module. Each group
of eight channels can be connected directly to positive or negative
supplies for high (hot) side switching. Alternatively, each group of
eight channels can be connected to common for low side switching.
Socketed pull-up resistors are provided for low side switching
applications. These resistors should be removed if high side
switching is needed. In low side switching applications the resistor
values can be changed (e.g. lower values will provide a faster pull-up
while a higher values will keep power dissipation from becoming a
problem at higher voltages) - see Specifications in Chapter 6 for
details.
The SSR’s are controlled by output registers within the FPGA.
Writing a ‘1’ to the output register will turn the switch ON (closed-
circuit) while writing a ‘0’ will turn it OFF (open-circuit). Readback of
the output state is accomplished by reading the output registers.
However, for complete confidence in output control, loopback should
be performed. This may be accomplished using the IP440 isolated
digital input module (refer to drawing 4501-603).
The SSR’s employed are rated for a much higher voltage than
specified. However, the field connector and printed circuit board foil
spacings limit applied voltages to +/-60VDC or AC peak. Each port
(group of eight channels) has a single common. Since the
connectors and cables are rated to 1A maximum per pin, then each
port is limited to that total current. Thus, the sum of currents
conducted by the 8 channels must stay below that total (see
specifications in Chapter 6 for details). The low on resistance of the
SSR’s helps reduce their power dissipation when they conduct high
currents; however, given the large number of channels on the board
adequate air circulation must be maintained. The SSR’s used in the
IP445 are very rugged and contain built-in current limiting for their
protection. They provide clean, bounce free switching and can
replace electromechanical relays in many applications. SSR
switching speeds are comparable to electromechanical relays (1mS.
typical) but are slow compared to high speed optocouplers.
Output operation is “Fail-safe”. That is, the outputs are always
OFF upon power-up reset, and are automatically cleared following a
software (control register) or system software reset. This is done for
safety reasons to ensure reliable control of the output state under all
conditions.
5.0 SERVICE AND REPAIR
SERVICE AND REPAIR ASSISTANCE
Surface-Mounted Technology (SMT) boards are generally
difficult to repair. It is highly recommended that a non-functioning
board be returned to Acromag for repair. The board can be easily
damaged unless special SMT repair and service tools are used.
Further, Acromag has automated test equipment that thoroughly
checks the performance of each board. When a board is first
produced and when any repair is made, it is tested, placed in a burn-
in room at elevated temperature, and retested before shipment.
Please refer to Acromag's Service Policy Bulletin or contact
Acromag for complete details on how to obtain parts and repair.
PRELIMINARY SERVICE PROCEDURE
Before beginning repair, be sure that all of the procedures in
Section 2, Preparation For Use, have been followed. Also, refer to
the documentation of your carrier board to verify that it is correctly
configured. Replacement of the module with one that is known to
work correctly is a good technique to isolate a faulty module.
CAUTION: POWER MUST BE TURNED OFF BEFORE
REMOVING OR INSERTING BOARDS
Acromag’s Applications Engineers can provide further technical
assistance if required. When needed, complete repair services are
also available from Acromag.
