GE IC610MDL101B – Circuit Module for Series One I/O System

This circuit module provides discrete output control for Series One PLC racks. It switches 24V DC loads like relays and indicator lamps. You can install this unit in any standard Series One I/O slot.

Key Technical Specifications

Physical Layout and Rack Mounting

This circuit module measures 127 mm in width and 89 mm in height. Its depth reaches 56 mm for standard Series One racks. The unit weighs 310 grams, allowing straightforward insertion into any slot. Two ejector tabs secure the module firmly to the chassis.

Internal Circuitry and Energy Storage

Eighty-six components populate this double-sided output board. A 1500 µF capacitor bank provides energy storage for inductive load switching. This bank absorbs back-EMF from solenoids and small motors. Consequently, the module protects output transistors from damaging voltage spikes. Each output includes a dedicated optocoupler for bus-to-field isolation.

Output Configuration and Wiring Details

Eight sink-type (NPN) outputs switch the DC common side of your loads. You connect the positive supply to your device, then wire the return to an output terminal. Each channel handles up to 1.0 amp continuously without external cooling. The total module current cannot exceed 4 amps across all active points. Removable terminal blocks accept solid or stranded wires from 0.2 mm² to 1.5 mm².

Protection Features and Diagnostics

Short-circuit protection shuts down an individual output within 50 microseconds. The module automatically attempts recovery after removing the fault condition. Thermal shutdown reduces current limit when internal temperature exceeds 85°C. Eight red LEDs show the on-off state of each output point clearly. Therefore, you can verify field wiring without a programming terminal or multimeter.
