General Electric IC693MDL645B Discrete Input Module

The General Electric IC693MDL645B Discrete Input Module is a 16-point AC input module for GE Fanuc Series 90-30 PLCs that receives digital signals from field devices on manufacturing lines, conveyors, material handling equipment, and automated machinery. It is used by maintenance teams and system integrators for repair, retrofit, expansion, or replacement of PLC input modules, delivering reliable input monitoring with optical isolation between field wiring and the backplane. Key specifications include 16 digital inputs at 120 VAC (AC input), approximately 7 mA per point, 50/60 Hz input frequency, optical isolation between field and backplane, power supplied via the PLC backplane, rack-mount on the Series 90-30 baseplate, and LED indicators per input with an operating temperature range of 0°C to 60°C. Common replacements include GE Fanuc IC693MDL645C, IC693MDL645D, and Siemens 6ES7321-1BH02-0AA0.
