GE Fanuc IC660BBS100 Genius Isolated I/O Block

The GE Fanuc IC660BBS100, also cataloged as the IC660BBS100 Isolated I/O Block, operates as a dedicated hardware component for 8-circuit AC/DC signal interface execution within GE Fanuc Genius I-O networks. It controls discrete input and output signals across an operating voltage range of 93 to 132 VAC or 105 to 132 VDC with 1500 V block-to-block galvanic isolation.

Hardware Specifications

Backplane Bus Communication Velocity and Network Determinism

The GE Fanuc IC660BBS100 transfers digital logic states across the Genius serial bus interface, maintaining high-velocity signal transmission and deterministic loop update execution. Network communication velocity operates at standard Genius protocol baud rates, providing real-time data frame synchronization between the remote I/O block and host controller modules. The unit features 1500 V block-to-block electrical isolation, protecting internal bus communications logic from high-voltage field spikes and ground potential differences. Firmware flash compatibility ensures transparent configuration via handheld programmers and seamless integration into existing Genius I-O drop layouts.

Frequently Asked Questions

Q: Can the IC660BBS100 electronic block assembly be replaced without powering down the Genius bus network?

A: Yes. The electronic block component can be unseated from its terminal assembly while the Genius serial communication network remains active. However, field power supplied to the AC/DC terminal block must be de-energized before block removal to prevent electric shock or damage to field contacts.

Q: What is the maximum continuous current capacity per output circuit on the IC660BBS100?

A: Each individual circuit on the IC660BBS100 is rated to supply a maximum steady state output current of 2.0 A across the operating range of 93 to 132 VAC (47 to 63 Hz) or 105 to 132 VDC.

Field Installation Guidelines

1. Mount the Genius terminal assembly onto a grounded panel or standard mounting rail prior to wiring field devices.
2. Connect the Genius serial communication cable to the bus terminals using shielded twisted-pair wire, applying standard bus termination resistors at the end nodes.
3. Wire field power and load circuits to the terminal block terminals, ensuring AC/DC line polarity and fusing adhere to local electrical safety standards.
4. Align the IC660BBS100 block electronics with the terminal base guides and press firmly until the multi-pin connector locks into place.
5. Tighten the central locking screw to firmly secure the electronic block assembly against industrial vibration.
6. Supply operating power and verify configuration settings using a Genius Hand-Held Monitor (HHM) attached to the front diagnostic port.
