General Electric IC693MDL645F Discrete Input Module

The GE General Electric IC693MDL645F Discrete Input Module provides 16 digital AC inputs for Series 90-30 PLCs, designed to receive 120 VAC signals from field devices on manufacturing lines, conveyors, material handling equipment, and automated machinery. Applications include machine control systems, assembly lines, packaging equipment, and process automation where reliable input monitoring is critical. Each input draws about 7 mA at 120 VAC and operates at 50/60 Hz, with optical isolation between the field and the backplane to improve noise immunity and protect the PLC; power is supplied via the PLC backplane. The module mounts on a Series 90-30 rack baseplate and features LED indicators per input point for status visibility, with an operating temperature range of 0°C to 60°C. Common replacements for IC693MDL645F include GE Fanuc IC693MDL645E, IC694MDL645, and Siemens 6ES7321-1BH02-0AA0.
