Repair GE-Emerson IC693MDL632 125VDC Positive/Negative Logic Input Module

The GE-Emerson IC693MDL632 125VDC Positive/Negative Logic Input Module includes a separate common associated with each group (the two commons are not tied together inside the module. The input module is designed to have either positive logic characteristics in that it sinks current from the input devices to the user common or negative power bus, or negative logic characteristics in that it sources current through the input devices to the user common or positive power bus. The input device is connected between the power bus and the module input. Current into an input point results in a logic 1 in the input status table (%I). Input characteristics are compatible with a wide range of input devices, such as pushbuttons, limit switches, and electronic proximity switches. Power to operate field devices must be supplied by the user.

LED indicators that provide the ON/OFF status of each point are located at the top of the module. This LED block has two horizontal rows with eight green LEDs in each row. This module uses the top row labeled A1 through 8 (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.
