General Electric IC693MDL645C Discrete Input Module

The GE General Electric IC693MDL645C Discrete Input Module is a 16-channel digital input interface for Series 90-30 PLCs, designed to collect signals from field devices on manufacturing lines, conveyor systems, and material handling equipment. It accepts 120 VAC digital inputs (AC input) at approximately 7 mA per point, operates at 50/60 Hz, and provides optical isolation between the field and backplane with power supplied via the PLC backplane; mounting is in a Series 90-30 rack-baseplate, and it uses LED indicators for each input point. The module supports a 0°C to 60°C operating range and is designed for reliable digital signal monitoring within machine control, assembly lines, packaging equipment, and process automation systems. Common replacements include GE Fanuc IC693MDL645D, GE Fanuc IC694MDL645, and Siemens 6ES7321-1BH02-0AA0.
