GE IC660BBD110 Discrete Input Block

The GE IC660BBD110, also cataloged as the IC660BBD110 Genius Block, operates as a dedicated hardware component for discrete AC input signal processing within GE Fanuc Genius I/O network platforms. It interfacing up to 16 AC circuits directly to the central processor over a serial communications bus without requiring a separate rack or power supply module.

Hardware Specifications

Backplane Bus Communication Velocity & Network Integrity

The IC660BBD110 integrates directly onto the Genius serial bus network, managing high-speed deterministic token-passing communication across shielded twisted-pair media. Bus speed configuration directly impacts packet scan latencies, enabling deterministic state transmission across distributed control architectures. Firmware flash compatibility within the Genius communications processor maintains strict protocol synchronization to prevent bus parity faults or packet collision frame dropouts during heavy I/O scanning cycles.

Frequently Asked Questions

Q: Does the IC660BBD110 support field insertion or hot-swapping while the Genius bus is active?

A: No, field wiring and terminal block connections must be completely de-energized and disconnected from the AC line voltage before servicing the physical block to prevent electrical arc hazards and bus communications interruptions.

Q: Can the 16 circuits on the IC660BBD110 accommodate both 2-wire and 3-wire field sensors?

A: Yes, the input circuitry is specifically configured to handle physical connections from both 2-wire proximity/limit switches and 3-wire powered switches operating at 115 VAC levels.

Field Installation Guidelines

1. Ensure the main power supply and all field circuit power sources are fully de-energized prior to mounting or wiring the block.
2. Mount the block securely onto a grounded metal panel using appropriate hardware to ensure low-impedance frame grounding.
3. Terminate the Genius serial communication cable using shielded twisted-pair wire. Maintain continuous shield continuity across all nodes, terminating the shield ground strictly according to system grounding topology to prevent ground loops.
4. Verify all AC field input wiring conforms to 115 VAC voltage tolerances and that wire gauges match terminal connection ratings.
5. Apply power and verify the LED diagnostic indicators display normal operating status before placing the loop into control execution.
