GE Fanuc IC660BBS102 Genius I/O Isolated Block Module

The GE Fanuc IC660BBS102, also cataloged as the IC660BBS102 Isolated Block I/O, operates as a dedicated hardware component for discrete signal processing and switching within Genius I/O network platforms. The module incorporates 8 circuits arranged in 4 isolated groups of 2 channels each, executing AC/DC field voltage switching while providing failed switch diagnostics and 250 VAC channel-group isolation.

Hardware Specifications

Dedicated Hardware Features

The IC660BBS102 block leverages high-speed backplane bus communication velocity across the serial Genius bus network to process discrete control logic with deterministic scan performance. Integrated electronic fusing on each channel detects short-circuit states, initiating circuit shutdown within 5 microseconds. With onboard firmware flash compatibility, the unit supports CPU redundancy, hold-last-state options, selectable input filtering, and failed switch diagnostics executed by comparing commanded output states directly against the internal switch switchgear state.

Frequently Asked Questions

Q: How does the failed switch diagnostic detection operate on the IC660BBS102?

A: The module continuously compares the internal microprocessor's commanded output state to the physical state of the internal solid-state switch device. A mismatch triggers an immediate failed switch diagnostic fault report over the Genius network.

Q: What happens when an output circuit experiences a short circuit or overcurrent fault?

A: The onboard electronic fusing mechanism detects overcurrent conditions and shuts down the affected output circuit within 5 microseconds, preventing thermal damage to the block assembly and field wiring.

Q: Can the IC660BBS102 block be restarted after a fault condition is cleared?

A: Yes, once the fault cause is corrected, a restart command can be transmitted directly from the master host controller CPU or via a Genius Hand-Held Monitor (HHM).

Field Installation Guidelines

1. Power Isolation: Ensure all 115 VAC / 125 VDC field power lines and logic power sources are de-energized before mounting or servicing the block.
2. Mounting Orientation: Secure the block directly to the panel baseplate using appropriate hardware; vertical panel mounting supports both right-side-up and upside-down orientations.
3. Shield Termination: Connect the Genius serial cable shield directly to the designated shield lug on the terminal connector frame to minimize high-frequency electromagnetic noise.
4. Thermal Spacing: Maintain a minimum 2-inch clearance above and below the block assembly to ensure natural convection cooling for maximum heat dissipation up to 45.6 W.
