GE IC693MAR590 Input output module
120 Volt AC Input, Relay Output, 8 Inputs/8 Outputs
IC693MAR590
The 120 volt AC Input/Relay Output module for the Series 90-30 Programmable Logic
Controller provides 8 input points with one common power input terminal, and 8 normally-open
relay circuits in the same module. The input circuits are reactive (resistor/capacitor) inputs and
are arranged as one group of 8 inputs. The output points are arranged in two groups of four
points each. Each group has a common power output terminal.
Input characteristics are compatible with a wide range of user-supplied devices, such as:
pushbuttons, limit switches, and electronic proximity switches. Current through an input results
in a logic 1 in the input status table (%I). Power to operate the field devices must be supplied
by the user. This module’s input section requires an AC power source, it cannot be used with a
DC power source.
The normally-open relay circuits are used for controlling output loads provided by the user.
The output switching capacity of each output is 2 amps. The relay outputs can control a wide
range of user-supplied load devices, such as: motor starters, solenoids, and indicators. Power
for the internal relay circuits is provided by the +24 volt DC bus on the backplane. The user
must supply the AC or DC power to operate field devices. There are no fuses on this module.
LED indicators which provide the ON/OFF status of each point are located at the top of the
module. The LEDs are arranged in two horizontal rows with eight green LEDs in each row.
The top row is labeled A1 through 8 (input points 1 through 8) and the bottom row is is labeled
B1 through B8 (relay output points 1 through 8). An insert goes between the inside and outside
surface of the hinged door. The surface towards the inside of the module (when the hinged door
is closed) has circuit wiring information, and circuit identification information can be recorded
on the outside surface. The outside left edge of the insert is color-coded red to indicate a
high-voltage module.
This module can be installed in any I/O slot of a 5 or 10-slot baseplate in a Series 90-30 PLC
system.
