GE Fanuc IC660EBD110 Genius I/O Electronics Assembly

The GE Fanuc IC660EBD110, also cataloged as the IC660BBD110 Electronics Assembly, operates as a dedicated hardware component for discrete AC input voltage sensing and signal isolation within Genius I/O bus networks.

Hardware Specifications

Backplane Bus Communication Velocity & Deterministic Network Execution

• Backplane Bus Communication Velocity: The assembly interfaces directly with the Genius serial bus via the terminal base, transferring discrete input state bit maps to the CPU controller with typical channel processing latencies of 1 ms plus configured filter delays (10 to 100 ms).
• Diagnostic Report & State Execution: Integrated voltage-sensing networks detect open-wire and shorted-wire conditions per channel, transmitting diagnostic fault packets over the Genius bus while driving local status LEDs (Unit OK, I/O Enabled, and 16 channel LEDs).
• Firmware & Hardware Compatibility: Designed for mounting on the IC660TBD110 terminal base, onboard logic maintains memory alignment across Genius I/O bus controllers without requiring firmware flashing during assembly replacement.

Frequently Asked Questions

Q: Can the IC660EBD110 electronics assembly be installed or removed while the terminal base is energized?

A: No. The IC660EBD110 does not support Removal and Insertion Under Power (RIUP). Main supply power to the terminal base must be completely disconnected before inserting or disengaging the assembly to avoid board damage or corrupted serial bus communications.

Q: What is the isolation capability between field input circuits and ground logic?

A: The input channels feature internal optocouplers and resistor-capacitor isolation networks rated for up to 1500 V continuous isolation between field input terminals, ground, and the internal serial communication bus.

Q: How does the IC660EBD110 handle 2-wire proximity switch field devices?

A: The unit incorporates a 11.6 kohm input resistance delivering a preload current of 9.9 mA at 115 VAC, which provides sufficient resistive leakage current drain to ensure reliable activation and off-state threshold detection for standard 2-wire AC proximity switches.

Field Installation Guidelines

1. Disconnect all AC power sources feeding the IC660TBD110 terminal base and connected field devices before starting installation.
2. Verify that the terminal base model is IC660TBD110 and that all terminal screws are properly secured.
3. Align the IC660EBD110 electronics assembly with the guide keys of the terminal base housing.
4. Press the assembly firmly onto the terminal base mating connectors until the mechanical latch mechanism clicks securely into place.
5. Ensure field input wiring utilizes recommended conductor gauges and that serial bus shield drain wires are tied to earth ground at a single node to suppress high-frequency noise.
6. Reapply main power to the assembly and observe the Unit OK LED indicator to confirm successful internal power-up diagnostics before placing the block online.
