GE IC610MDL126A | Series Six Input Module 120V AC 16 Channel

The IC610MDL126A reads AC signals from field sensors and limit switches. This input module serves the legacy Series Six PLC platform reliably. It provides sixteen discrete channels for monitoring industrial machine states. Consequently, you can track contactors, pilot devices, and proximity sensors directly.

You can use this module with standard 120V AC control circuits. The IC610MDL126A accepts voltages from 85V to 132V AC nominal. Each channel includes optical isolation for excellent electrical noise rejection. Therefore, this module delivers clean input data in high-noise industrial environments.

Input Specifications and Channel Details

The module features sixteen input channels with a common return arrangement. Each channel on the IC610MDL126A detects logic high above 70V AC. It recognizes logic low when the voltage falls below 20V AC. The module filters input signals to prevent false triggering from line noise.

Inputs respond to state changes within one AC cycle typically. The IC610MDL126A draws approximately 8 mA per active input channel. An LED on the front panel illuminates when the corresponding input activates. Below is a complete breakdown of its technical characteristics.

Interface and Field Wiring Connections

A removable terminal block accepts all field input wiring. The IC610MDL126A uses screw-clamp terminals for secure wire retention. Each terminal accepts wire sizes from 0.5 to 2.5 mm². The module connects to the Series Six backplane via a standard edge connector.

You can connect both normally open and normally closed contacts easily. The IC610MDL126A works with standard 120V AC pilot devices. Individual LEDs provide visual confirmation of each active channel. Therefore, troubleshooting field wiring becomes a straightforward visual task.

Operational Benefits for Legacy Systems

This input module replaces original Series Six components in older systems. The IC610MDL126A maintains compatibility with existing 120V AC field wiring. Its high noise immunity works perfectly in motor control centers. Engineers trust this module for maintaining legacy GE automation systems.
