GE Fanuc IC660ELB910 Digital Output Module

The GE Fanuc IC660ELB910 is a 16-point discrete digital output module designed for Series 90-30 PLC systems. Built for industrial automation environments, this module provides reliable switching of DC loads while supporting fast response times and precise control. From an engineer’s perspective, it’s a practical choice for both centralized racks and distributed I/O systems, simplifying wiring and reducing field troubleshooting time.

Its compact design allows it to fit into standard PLC racks while providing robust protection against overcurrent and short-circuit conditions, making it suitable for critical industrial processes.

Technical Specifications

Applications

The IC660ELB910 is ideal for industrial control applications requiring high-speed discrete outputs:

• Manufacturing Lines – controlling solenoids, indicator lamps, and relays.

• Conveyor Systems – precise activation/deactivation of diverters and stops.

• Packaging Machinery – timing-controlled output for actuators.

• Water & Wastewater Plants – controlling valves, alarms, and indicators.

• Energy Systems – triggering alarms or interlocks in distributed control.

Its fast response and modular design make it practical for both central PLC racks and field-distributed architectures.
