Discrete Output Modules
Isolated Relay Output, N.C. and Form C, 8 Amp - 8 Point
IC693MDL931
This 8 Amp Isolated Relay Output module for the Series 90-30 Programmable Logic Controller
provides 4 normally-closed and 4 Form C relay circuits for controlling output loads provided by
the user. The output switching capacity of each circuit is 8 amps for the normally-closed
contacts or the normally open contacts. Each output relay is isolated from the other relays, and
each relay has a separate common power output terminal. The relay outputs can control a wide
range of user-supplied load devices, such as: motor starters, solenoids, and indicators. The user
must supply the AC or DC power to operate the field devices connected to this module. 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.
This module uses the top row labeled A1 through 8 (points 1 through 8) for output status; the
bottom row is not used and the fuse LED is not used. 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.

For inductive loads
Relay contact life, when switching inductive loads, will approach resistive load contact life if
suppression circuits are used. The following figures are examples of typical suppression
circuits for AC and DC loads. The 1A, 200V diode shown in the DC load typical suppression
circuit is an industry standard 1N4935. The resistor and capacitor shown for AC load
suppression are standard components, available from most electronics distributors.
