1 Overview
The 5604 I/O module is an integrated component of a SCADAPack Series controller and not
available as a standalone unit. The following controllers support the 5604 I/O module:
SCADAPack P1A - A 520x controller board with an integrated 5604 I/O Module.
SCADAPack P4A - A 5232 controller board with an integrated 5604 I/O module.
The 5604 I/O module increases the I/O and communication capacity of a SCADAPack controller by
providing 9 single ended analog inputs, 32 digital inputs/outputs, two analog outputs (optional) and
one RS-232 serial communication port. This I/O module also has a 12V to 24V boost converter
power supply capable of generating 24V at 0.25A for up to twelve 20mA transmitters or loads.
Note that this I/O module is not available as a standalone unit.
The analog inputs can be configured for current or voltage mode with a measurement ranges of 0-
20mA or 0-10V respectively. Analog inputs can also be configured with a 20% offset in the
measuring range. In current mode, a 250current sense resistor appears across each analog input
channel. The 250resistor produces a voltage drop of 5V for a 20mA of current flow. All analog
input channels are transient protected, optically isolated from the main logic supply and share a
common return (COM) that is connected to the chassis.
This I/O module uses a 16-bit successive approximation A/D converter and provides 15 bit
resolution over the range of the analog input. Analog Input 8 is a 0 to 32.768-volt input that
measures with 10-bit resolution and can be used to monitor a power supply or battery voltage.
There is one internal analog input that is used in application programs to monitor the DC/DC
converter voltage used for VLOOP.
The 5604 I/O module can be equipped with an optional 5305 Analog Output Module that provides
two 20mA outputs through a 12-bit D/A converter. The analog outputs are transient and over
voltage protected. The output channels share a common return (GND) and with the analog input
channels.
32 universal digital inputs/outputs are provided onboard this I/O module. Each digital I/O point can
be used as an input or an output only. The inputs can be used to monitor the status of that output. In
addition to the 32 universal digital input/outputs there are 3 internal digital inputs and 2 internal
digital outputs that are used to monitor and control a DC/DC converter or VLOOP power supply as
well as to monitor digital output mismatch status.
The inputs are intended for use with dry contacts such as switches, open collector transistors and
relay contacts. Wetting current for the contacts is provided. All GND terminals on the I/O module
are connected internally to the SCADAPack chassis.
Outputs are open-collector/open drain type for use with sustained DC loads of up to 1 ampere.
Loads with high in-rush currents may exceed the 1A rating. The output circuit will tolerate these
higher peak currents. Inductive load transient suppression is built into each digital output point. It is
not necessary to add additional inductive load transient suppression unless highly inductive loads
(greater than 1H) are operated continuously at greater than 0.5Hz.
Note: This manual covers the powering, wiring and configuration of a 5604 I/O module only. It is
meant to be used with the hardware manual of the respective controller board to which the
I/O module is attached.

4.1 Overview and Requirements
The 5604 I/O module requires 11-24Vdc applied to the AC/DC PWR IN terminals on connector P3
of the I/O board to power the analog input and optional analog output circuitry.
The current requirement of the analog portion (input and optional output circuitry) on the 5604 I/O
board can vary from a minimum of 10mA for basic operation of the analog circuitry to a maximum
of 550mA if all analog inputs, optional analog outputs and the 24V boost converter requires full
power to provide 6W (250mA @24V) of power.
The user has three options to supply 11-24V to the I/O board as outlined below but should
thoroughly examine the application and supply the 5604 I/O Module with a suitable power source.
Note: Voltage referred to as Vrms (or VAC on some products) indicates AC power. Voltage
referred to as V indicates DC power.
4.2 Power Supply Input Connections

4.2.4 Recommended 5103 Power Supply Configuration
When additional power is required by the system, 5000 Series 5103 power supplies can be used in
combination with the SCADAPack controllers. Refer to the System Configuration Guide for more
information.
The 5103 power supplies can be connected anywhere downstream (to the right) of the controller.
They will supply power to the modules downstream of them.
Note: The Sleep Mode feature of the controller applies only to those modules powered by the
controller.
The 5103 power supply may also be connected upstream (to the left) of any SCADAPack
Controller, but only if the following conditions are observed:
No power is applied to the power inputs of the controller board.
A jumper is installed at position J5 (see the user manual of your respective controller board for
details.
The sleep mode feature is not used.
This configuration uses a 5103 Power Supply module to power a SCADAPack controller. The
24VDC output from the 5103 powers the 5604 I/O module. The 5103 power supply provides a 5V
output to power the 5604 I/O module, the controller board and 5000 Series modules through the
IMC cables.

4.3 System Grounding
In most applications, it is desirable to ground the system by connecting the system power supply
common, to the chassis or panel ground.
On the 5604 I/O module, “-“ terminal of the 24V supply(DC PWR “-“) is already connected to the
enclosure by the printed circuit board traces.
4.4 Power Management Features
The 5604 I/O board provides a number of special features to reduce power consumption. These
power management features include:
VLoop power control.
12V to 24V DC/DC Converter Control.
The 5604 I/O module provides two internal digital outputs that can be operated by the user
application to manage the power saving features. Internal digital outputs 32 and 33 and the power
management functions they control are described in the following sections.
Refer to Figure 6: Power Management for an overview of the power management features. Refer
to the appropriate software manual for information on using and controlling the internal Digital
Outputs. For TelePACE applications refer to the Register Assignment for the SCADAPack 5604 I/O

The 12V to 24V DC/DC converter is used to provide 24 VDC for VLoop power and for the Analog
Output module. The converter should be turned on if the 5604 I/O Module is equipped with analog

5604 Input/Output (I/O) Module - Hardware Manual

14
outputs for which 24V-drive capability is required. Otherwise, the DC/DC converter can be turned
off to conserve power.
Turn on Digital Output 32 to turn ON the 12V to 24V DC/DC converter. When the converter is
turned on 24Vdc is provided to the VLoop power and to the Analog Output module.
Turn off Digital Output 32 to turn OFF the 12V to 24V DC/DC converter. When the converter
is turned off VLoop power and the Analog Output module use is the applied input power.
Internal Digital Input 32 indicates the status of the 12V to 24V DC/DC converter. Digital Input 11
is set when the 12V to 24V DC/DC converter is on and is cleared when the 12V to 24V DC/DC
converter is off.
The 12V to 24V DC/DC converter is turned on when the LED power is enabled. This feature is
provided for service and diagnostics. Refer to the LED Power Control section in the hardware
manual of your respective controller board for further information on this feature
4.4.2 VLoop Power Control
The DC/DC converter output can be used to power analog input current loops or other
instrumentation. This output, VLoop, is controlled for intermittent or continuous operation. Turning
the VLoop output off when it is not required can save considerable electrical power.
The switched VLoop power source is the output of the DC-DC 12/24V converter if it is turned on.
See the DC/DC Converter Control section for converter information. The VLoop power source is
the applied input power if the DC-DC converter is turned off.
Turn on Digital Output 33 to turn ON the VLoop output.
Turn off Digital Output 33 to turn OFF the VLoop output.
Note: When VLoop is first turned on, the user application program must wait at least one second
for input readings to stabilize. This time may be increased depending on field sensors and
transmitters. Documentation for these devices should be consulted.
The VLoop output is turned on when the LED power is enabled. This feature is provided for service
and diagnostics. Refer to the LED Power Control section in the hardware manual of your respective
controller board for further information.
4.4.3 VLoop Over-Current Protection
When VLoop output is turned on, it is monitored for excessive current consumption caused by field
wiring or instrumentation problems. If sustained over-current is detected (100 ms), VLoop is turned
off even though internal Digital Output 33 is turned on. This protection prevents unnecessary fuse
blowing, circuitry damage and rapid battery depletion.
When VLoop output is turned on, using internal Digital Output 33, and a short circuit is detected
VLoop will turn off. VLoop will turn on to try again 5 seconds after turning off. If the fault
condition still exits VLoop will again turn off and retry after a 5 second delay. While the fault
condition exists internal Digital Input 34 will be ON.

5 Analog Inputs
The 5604 I/O module enhances the capacity of a SCADAPack controller by providing an additional
nine single ended analog inputs on connector P4, that can be configured for current or voltage mode.
Refer to Figure 1: 5604 I/O Module Layout for the location of this connector.
Analog Inputs 0-7 can be configured for current or voltage mode using jumper switches. Please refer
to section 5-Analog Inputs on how to select input modes.
In voltage mode, these analog inputs are single ended and the measurement range is 0-10V. The
range is selected via the configuration DIP switches. Refer to section 5.2- Range and
Resolution below for details.
In current mode, a 250current sense resistor appears across each analog input channel.
Measurement range in current mode is 0-20mA or 4-20mA selectable via the configuration
switches. The 250resistor produces a voltage drop (input reading) of 5V for a 20mA of
current flow.
All analog input channels are transient protected, optically isolated from the main logic supply and
share a common return (COM) that is connected to the chassis.
The controller uses a 16-bit successive approximation analog to digital (A/D) converter and provides
15 bit resolution over the range of the analog input.
Analog Input 8 is a 0 to 32.768-volt input that measures with 10-bit resolution and can be used to
monitor a power supply or battery voltage.
There is one internal analog input that is used in application programs to monitor the DC/DC
converter voltage used for VLOOP.
For TelePACE applications use the SCADAPack 5604 I/O Module register assignment to read
the nine external and the internal analog inputs.
For ISaGRAF applications use the sp5604 I/O connection to read the nine external and the
internal analog inputs.
Please refer to the respective TelePACE and ISaGRAF software manuals on how to assign the above
registers to read these input ports.
5.1 Current or Voltage Mode
Analog Inputs 0-7on connector P4 can be configured for either voltage or current mode using
jumper links. The jumper links reside on the lower I/O board itself. To access the jumper links, the
main cover and controller board will have to be taken off by removing the retaining screws.
Note: Analog Input channels 0-7 are configured for current mode by default.
To select current mode, install the jumpers on the side labeled 20mA on the I/O board as shown in
the figure below for analog inputs 0-5. In current mode a 250resistor appears across the input
channel.

Analog input 8 is configured for voltage mode only. Voltage ranges of up to 32.768V are
measurable using a 10 bit A/D converter and represented with 15 bits of data. The input resolution
on this channel approximately 0.03V/count.

5.3 Wiring
The analog inputs support loop powered and self powered transmitters. Loop powered transmitters
are two terminal devices that connect between a power supply and the analog input. The loop
current continues from the power supply, through the transmitter and to ground through a 250
resistor built into the 20mA input circuit. Self-powered transmitters have three terminals called
power in, signal out and common. Self-powered transmitters can have a current or voltage output.
The signal out connects to the Analog Input Channel, the common connects to GND and the power
in connects to a power supply.
There are three options for the user when selecting the power source. In all cases it is important for
the user to ensure that the transmitter has enough voltage for proper operation. The transmitter
manufacturer supplies the minimum operating voltage specification of the transmitter. The analog
input requires a minimum of 5V.
The first option is to use the 5604 I/O Module VLOOP Supply that boosts the input voltage to 24V
with a 12V to 24V DC/DC converter. The stepped up voltage is available on connector P3 and is
labeled VLOOP. There is sufficient power available for the eight analog inputs and four analog
outputs all operating at 20mA. Significant power saving is possible by switching the VLOOP supply
off when measurements are not being made.
The second option is similar to the first except that the power supply is not boosted up to 24V. This
can be used with low voltage transmitters or when the input voltage is sufficiently high that further
boosting is not necessary. It is still possible to switch the supply off under program control. When
the step up is turned off, VLOOP is approximately 0.5V less that the power input voltage.
5.3.1 Wiring Examples
Several wiring examples for loop and self powered transmitters are illustrated in Figure 8: Analog
Input Wiring. The transmitters are wired as follows:
Channel 0 has a loop powered current transmitter connected to VLOOP.
Channel 1 has a self-powered voltage transmitter connected to the external power supply.
Channels 2 through 6 are unused.
Channel 7 has a self-powered current transmitter connected to the external power supply.
Channel 8 is used to monitor the external power supply.
If a 12V external power supply or battery is used the application can boost this voltage to 24V at
VLOOP using the internal DC/DC converter. If a 24V external power supply is used it is
unnecessary to boost this voltage.

5.4 Filtering and Response Timing
The 5604 I/O Module also provides internal digital outputs to control the filtering and response
times of the analog to digital conversion. Theses digital outputs can be controlled by the user
application to either maximize the filtering in noisy environments or minimize the filtering in
applications that require the fastest response times.
The following chart shows the response timing for the selectable filter settings.
Internal digital outputs 34 and 35 control the filter setting.
The 5604 I/O module may select 50 or 60 Hz line frequency for digital and analog input processing.
The Controller board Option Switch 3 selects the line frequency option.

6 Analog Outputs
The 5604 I/O Module may include two channels of analog output if this option was requested at
time of purchase.
For TelePACE applications use the SCADAPack AOUT I/O Module register assignment to
write to the two analog outputs.
For ISaGRAF applications use the aout2pt I/O connection to write to the two analog outputs.
Please refer to the respective TelePACE and ISaGRAF software manuals on how to assign the above
registers to read these input ports.
6.1 Current Outputs
The 5604 I/O Module can be equipped with an optional 5305 Analog Output Module that provides
two 20mA analog outputs. Analog output resolution is 12 bits. The outputs are transient and over
voltage protected. The outputs share a common return (GND) with each other and the 5604 I/O
Module analog inputs.
The 12V to 24V DC/DC boost converter powers the analog outputs. The boost converter is used to
boost the DC input power to 24V. The application program may control the boost converter.
