Description

24 Volt DC Input, Relay Output, 8 Inputs/8 Outputs
IC693MDR390
The 24 volt DC 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 designed to have either
positive or negative characteristics in that they sink or source current to/from the input devices
to/from the user common and are arranged as one group of 8 inputs. The relay output circuits
are arranged in two groups of four circuits 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.
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 top half of the outside left edge of the insert is
color-coded blue to indicate low-voltage circuits and the bottom half of the outside left edge is
color-coded red to indicate high-voltage circuits.
This module can be installed in any I/O slot of a 5 or 10-slot baseplate in a Series 90-30 PLC
system.
