Product description:

The IC693MDL640 is a 24 Volt DC positive logic input module for the GE Fanuc Series 90-30.  This module provides 16 input points in one group with a common power input terminal. This input module is crafted to have positive logic characteristics, meaning it sinks current from the input devices to the user common or negative power bus. The input device is connected to the positive power bus and the module input. A current running into an input point results in a logic 1 in the input status table.  The module’s Input characteristics make it compatible with a wide range of input devices such as pushbuttons, limit switches, and electronic proximity switches. 

The 2 Amp Relay Output module for the Series 90-30 Programmable Logic Controller provides 16 normally-open relay circuits for controlling output loads provided by the user. The output switching capacity of each output is 2 amps. The output points are arranged in four groups of four points each. Each group has a common power output terminal. 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.

The following figure provides wiring information for connecting user supplied load devices and power source to the 2 amp N.O. Relay output module.

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 suppression circuit is an industry standard 1N4935. The resistor and capacitor shown for AC load suppression are standard components, available from most electronics distributors
