Description

The GE IC660BBD110 and GE IC660EBD110 are complementary digital I/O modules within General Electric’s Genius I/O family, designed for use with the Series 90-30, 90-70, and VersaMax programmable logic controller (PLC) platforms. The GE IC660BBD110 is a 16-channel discrete DC input module that senses field signals from switches, pushbuttons, or proximity sensors, while the GE IC660EBD110 is a 16-channel electromechanical relay output module capable of switching AC or DC loads up to 2A per point. Together, they form a robust, high-isolation I/O solution for industrial automation applications requiring reliable on/off control.

Both modules communicate over GE’s proprietary Genius bus—a deterministic, token-passing network that supports up to 31 remote I/O stations with millisecond-level scan times. The GE IC660BBD110 features optical isolation (1500 V RMS) and configurable sink/source wiring, making it adaptable to diverse sensor topologies. Meanwhile, the GE IC660EBD110 employs gold-flashed relay contacts for long life and low contact resistance, suitable for controlling solenoids, motor starters, indicator lamps, and small contactors. Each module includes front-panel LEDs for real-time channel status monitoring, greatly simplifying troubleshooting during commissioning or maintenance.

Engineered for harsh plant-floor conditions, the GE IC660BBD110 and GE IC660EBD110 operate reliably in environments with wide temperature swings, electrical noise, and mechanical vibration—common in power generation, water/wastewater, material handling, and discrete manufacturing systems.

Technical Specifications

Main Features and Advantages

Flexible and rugged input handling:
The GE IC660BBD110 accepts a wide DC voltage range (5–30 V) and supports both sinking and sourcing field wiring through simple terminal block configuration—eliminating the need for external interface relays in mixed-sensor installations. Its high common-mode rejection ratio ensures immunity to ground potential differences, a frequent issue in large facilities with distributed grounding systems.

High-power, versatile output capability:
Unlike solid-state outputs limited to DC loads, the GE IC660EBD110 uses electromechanical relays that switch both AC and DC circuits, offering true galvanic isolation and compatibility with legacy equipment. Each relay is rated for 100,000+ operations at full load, making the GE IC660EBD110 ideal for infrequent but critical actions like emergency shutdowns or valve actuation.

Seamless Genius I/O integration:
Both the GE IC660BBD110 and GE IC660EBD110 plug into standard Genius I/O bases and auto-configure via the bus—no DIP switches or software addressing required. They support hot insertion/removal when used with compatible bases, minimizing downtime during module replacement. Diagnostic data (e.g., open-circuit detection on inputs, relay coil faults on outputs) is reported directly to the PLC CPU for predictive maintenance.

Cost-effective scalability:
By leveraging the decentralized Genius architecture, users can place GE IC660BBD110 and GE IC660EBD110 modules near field devices—reducing copper costs and signal degradation over long cable runs. This modular approach also allows incremental system expansion without redesigning the entire control cabinet.

Application Field

The GE IC660BBD110 and GE IC660EBD110 are extensively used in industries where reliable discrete I/O is essential but extreme speed is not required. In municipal water treatment plants, the GE IC660BBD110 monitors pump run status, valve limit switches, and high-level alarms, while the GE IC660EBD110 energizes chemical dosing pumps and backwash valves—often in outdoor enclosures exposed to humidity and temperature extremes.

In packaging and material handling lines, these modules interface with photoelectric sensors, safety interlocks, and conveyor motors. The relay outputs of the GE IC660EBD110 are particularly valued for driving older motor contactors that require AC coil voltages, bridging the gap between modern PLCs and legacy machinery. Similarly, in small hydroelectric or biomass power units, the GE IC660BBD110 reads breaker position signals, and the GE IC660EBD110 controls excitation contactors or cooling fan circuits.

Because of their compatibility with both Series 90 and VersaMax controllers, the GE IC660BBD110 and GE IC660EBD110 are also popular in retrofit projects—allowing end-users to modernize I/O without replacing the entire PLC system. Their straightforward diagnostics and robust construction make them a go-to choice for OEMs and system integrators building skid-mounted process units for oil & gas, food & beverage, and pharmaceutical applications.
