GE IC660BBR101 Genius Relay Output Module

The GE Fanuc IC660BBR101, also cataloged as the IC660BBR101 Relay Output Module, operates as a dedicated hardware component for discrete high-voltage contact switching execution within GE Fanuc Genius I/O networks. It routes control logic from the serial bus to 16 normally open relay output circuits handling load switching from 5 to 250 VAC or 5 to 220 VDC.

Hardware Specifications

Backplane Bus Communication Velocity and Firmware Compatibility

The GE Fanuc IC660BBR101 updates output contact states across the serial Genius bus interface, maintaining high communication velocity and deterministic execution cycles across distributed I/O drops. Serial bus transmissions operate at 153.6 kbaud, transferring discrete command frames directly to internal electromechanical relay driver stages. Optical and mechanical isolation barrier designs prevent high-voltage switching noise on field contact lines (up to 250 VAC / 220 VDC) from corrupting internal processor communication logic. Firmware flash compatibility across Genius bus controllers allows transparent block identification, diagnostics reporting, and logic mapping without modifying host CPU scan routines.

Frequently Asked Questions

Q: Can the IC660BBR101 electronic block assembly be replaced without breaking communication on the Genius serial bus?

A: Yes. The electronic block assembly can be unseated from its permanent terminal assembly while the active Genius serial cable loop continues communicating with adjacent blocks. Field operating power to the 115/230 VAC supply and load circuits should be de-energized prior to removal.

Q: What contact configuration and output voltage limits are supported by the IC660BBR101?

A: The IC660BBR101 provides 16 normally open (NO) relay output contact circuits rated for operational switching from 5 to 250 VAC or 5 to 220 VDC.

Field Installation Guidelines

1. Mount the terminal assembly onto a grounded panel plate or standard DIN enclosure surface before landing field cables.
2. Connect the shielded twisted-pair Genius serial communication cable to the bus terminals, ensuring correct daisy-chain topology and line termination resistors (75 or 100 ohms).
3. Land incoming 115/230 VAC (50/60 Hz) operating control power wires and field load circuits on the designated terminal block points.
4. Align the IC660BBR101 electronic block with the mounted terminal base guides and push firmly until internal multi-pin connectors mate fully.
5. Tighten the central retention screw to secure the block assembly against machinery vibration.
6. Apply control power and assign the block address using a Genius Hand-Held Monitor (HHM) attached to the front diagnostic serial connector.
