RELAY DRIVER BOARDS
Compact Assembly
The xx03DVR Board is designed to to mate
with ICS's xx03 Parallel Interface Cards that have
their digital connector mounted on the circuit
side so the connector faces down. The Interface
Boards plug down into the xx03DVR Board as
shown in Figure 1 so the LEDs and I/O connectors
are available to the user. This makes a compact
assembly that is only 4.5 inches wide by 7 inches
long. Height depends upon which board is being
used with the xx03DVR Board.
A version of the xx03DVR Board is avail-
able for standard xx03 Parallel Interface Cards
but it sits on top of the Parallel Interface Card,
covers the I/O connectors and and adds to the
assembly height.

The xx03DVR Board expands the
output drive capability of ICS's 40-line
Parallel Interface Boards by adding heavy-
duty solenoid drivers to each output signal.
The xx03DVR is designed so that the user
can use 24, 32 or all 40 digital lines with so-
lenoid drivers to operate relays and other heavy
loads. When just 32 or 24 lines are used for relay
drivers, the remaining eight or sixteen lines can
be used as standard board TTL I/O lines. The
xx03DVR Board also converts the relay power
supply voltage into 5 Vdc for powering itself and
the Parallel Interface Board. This eliminates
the need for a separate 5 volt power supply. The
xx03DVR board works with connector down ver-
sions of ICS's 2003, 2303, 4803 and 8003 Parallel
Interface Cards.
High Current Relay Drivers
The xx03DVR Board is equipped with 40
open-collector darlington type drivers that can
sink up to 500 mA to operate relays, solenoids or
other heavy loads. The rugged relay drivers can
handle voltages up to 48 volts. The xx03DVR's
driver circuits have been designed to be glitch
free so as to not pulse the external relays at power
turn-on or turn-off. The output drivers can be
operated by bit commands that toggle one bit at
a time, by byte-wide commands that control 8
bits at a time or by string commands which can
control multiple bytes at a time.

Driver Output Lines
The xx03DVR Board can be congured so that
all 40 lines are relay driver outputs or the rst 8 or
16 digital I/O lines can be connected directly to
the Parallel Interface board and used as standard
TTL I/O lines. Rocker switches and jumpers on the
xx03DVR Board bypass the relay drivers on bytes 1
and 2 and connect the terminal strip signals directly
to the interface board.
The conguration choices are:
TTL I/O Relay Driver Outputs
0 40
8 32
16 24
The driver operation is shown in the partial sche-
matic in Figure 2. A high input to the driver circuit
causes it to pull the output to ground and turn the
relay or other device on. A low input turns the driver
off. The external load pulls the signal high. The
xx03DVR does not supply any high side voltage.
When the drivers are bypassed, the output lines are
connected directly to the Parallel Interface Board's
high current TTL lines. The bypassed lines can be
used as inputs or outputs just as it they were directly
connected to the Parallel Interface Board connector.
The TTL lines do supply a small amount of current
from the 5 volt bus and have 33 kohm pullup resi-
tors that pull the lines high to sense open contacts
and lines.
xx03DVR Board Description
The xx03DVR Board terminal strip connections
are identied by bytes and bit, so they easily relate
to the signals on the companion Interface Board.
Standard bit commands like ROUTe:CLOSe or
ROUTe:OPEN can then be used to operate the relay
drivers. Set the Output polarity to high true for the
relay driver signals.
An External Reset input can be used to reset the
Interface board.
Built-in Power Supply
The xx03DVR can be powered from the same
power supply that drives the external relays. The
relay power is used as the return for the drivers'
internal anti-backlash diodes and to power
the Parallel Interface Board. The user should
still use relays with built-in anti-backlash
diodes to minimize RFI. The xx03DVR contains
a small switching regulator that converts 4 VA of
relay power into 5 Vdc to power the companion digital
board,. This eliminates the need for a separate 5 volt
power supply.

xx03DVR Board Assemblies
Figures 4 and 5 show how a 2003, 2303, or 4803
Parallel Interface Board with a circuit-side connector
mounts on the xx03DVR Board. The Parallel Interface
Board is positioned over J1 on the xx03DVR Board and
pressed into place. A pair of 0.688 high female-to-male
standoffs holds the front portion of the two boards
together. The rear portion is held by the mating force
of the 64 pin DIN connectors. Signal and power wires
are attached to the xx02DVR terminal blocks.
Figure 5 shows the 115848 '8003' type board
mounted on the xx03DVR board. Its height is slightly
bigger due to the vertical RJ45 connector on the 8003.
An 8003H will not mate with the 115490 xx03DVR
Board
A version of the xx03DVR Board is available with
a female connector on its circuit side so it can sit on
top of standard 2003, 2303, 4803 and 8003H boards.
Mounting the xx03DVR Board on top of standard
boards adds 0.6 inches to the overall assembly height
as shown in Figure 3.
A pair of 0.688 high standoffs holds the two boards
together. Standard 8003s with their vertical RJ-45
connector cannot be used with the 115522 xx03DVR
Board because the board blocks the RJ45 connector.
