GE IC660BBD100 I/O Modules

The GE IC660BBD100 serves as the primary IC660BBD100 Genius Block utilized to execute discrete AC input signal processing across GE Fanuc Genius I/O platforms. This standalone unit interfaces 8 discrete AC circuits directly to the serial communications network without requiring an external rack interface or dedicated power supply module.

Hardware Specifications

Backplane Bus Communication Velocity & Network Integrity

The IC660BBD100 interfaces directly with the Genius serial communication bus using a deterministic token-passing protocol to maintain real-time signal processing. Configuring network baud rates directly controls packet transmission latencies and scan synchronization across distributed nodes. Strict firmware flash compatibility within the internal communications controller prevents frame corruption, bus collision errors, and network disconnects during continuous I/O scan iterations.

Frequently Asked Questions

Q: Can the IC660BBD100 be wired to both 2-wire and 3-wire proximity switches?

A: Yes, the 8 discrete input circuits on the block are designed to accept wiring configurations for both 2-wire and 3-wire field sensors operating on 115 VAC control loops.

Q: Is a standalone chassis rack or external power supply module required for operation?

A: No, the Genius block uses a rackless design and derives its required operational power directly from the 115 VAC line voltage wired to its terminals.

Field Installation Guidelines

1. Ensure all incoming 115 VAC field power and serial communication lines are completely de-energized before beginning installation or maintenance.
2. Secure the block directly to a clean, conductive panel surface using appropriate mounting hardware to maintain a low-impedance connection to frame ground.
3. Terminate serial communication lines using approved shielded twisted-pair wire, ensuring continuous shield integrity across the network nodes and grounding the shield according to system design to prevent ground loop noise.
4. Confirm all field wiring terminations meet 115 VAC electrical specifications and are securely tightened to the terminal strip.
5. Apply operating voltage and confirm the unit status LEDs indicate proper initialization before putting the system online.
