IC660BBS100 GE Fanuc Isolated I/O Block 8 Circuits

IC660BBS100 Isolated I/O Block from GE Fanuc

The IC660BBS100 belongs to the GE Fanuc Genius I/O series. This block delivers 8 I/O circuits across 4 isolated groups. Each group has two circuits. Isolation between any two groups withstands 250 VAC or VDC continuously. Transient rating reaches 2000 Volts peak for 10 seconds. You can configure this block for input-only, output-only, or mixed operation.

Key Technical Specifications

The IC660BBS100 operates at 115 VAC or 125 VDC nominal voltage. AC voltage range runs from 93 to 132 Volts. DC voltage range spans 105 to 132 Volts. AC frequency range sits at 47 to 63 Hertz. Each circuit handles 2 Amps of current. Peak output current per block reaches 15 Amps at 35°C. At 60°C, the peak output current drops to 7.5 Amps. Heat dissipation measures 16.8 Watts.

Electronic Protection Features

Electronic fusing exists for every output circuit. A short circuit triggers shutdown after 5 microseconds. AC circuits have a 100-millisecond internal electronic short circuit trip. DC circuits use a 10-millisecond long time trip. You can restart the block easily from the CPU or a handheld monitor. This protection prevents damage to both the block and connected field devices.

LED Status Indicators

Each circuit on the IC660BBS100 has its own LED. For a circuit configured as an input, the LED indicates threshold voltage status. For a circuit configured as an output, the LED shows the mode set by the CPU. These indicators help you verify circuit operation at a glance. Use them during commissioning and troubleshooting to save time.

Environmental and Mechanical Ratings

The IC660BBS100 operates between 0°C and 60°C. Storage temperature spans -40°C to 100°C. Humidity tolerance reaches 5 to 95% non-condensing. Power supply dropout time equals 10 milliseconds per cycle. Power consumption for control circuits maxes at 8 Watts. Module dimensions measure 8.83 x 3.5 x 3.94 inches. Approximate weight is 4 pounds.

Wiring and Field Connections

During field wiring, you need only standard tools. Screws and screwdrivers work for all connections. Each terminal block accepts one AWG #12 wire. It also accepts two AWG #22 wires. Ring terminals with width up to 0.27 inches fit as well. The minimum opening accommodates a #6 screw. This flexibility makes installation straightforward.

Compatibility Information

The IC660BBS100 works with GE Fanuc handheld monitors. Compatible models include IC660HHM501 and IC660HHM500. You can use it with any GE Fanuc bus controller. The block is backward compatible with previous versions. Note that GE Fanuc has replaced this model with the IC660BBS102. However, the IC660BBS100 remains available as new surplus or refurbished stock.

Application Examples

Use the IC660BBS100 where circuit isolation matters. Mixed input and output applications benefit from its flexibility. Industrial environments with potential short circuits need its electronic fusing. Systems requiring diagnostic feedback will use its fault reporting. Applications with both AC and DC devices can leverage its dual power support.

FAQ

1. Can the IC660BBS100 mix inputs and outputs on the same block?
   Yes, configure it as a combination block. This allows some circuits as inputs and others as outputs within the same module.

2. What happens when a short circuit occurs on an output?
   The electronic fuse trips after 5 microseconds. The circuit shuts down to prevent damage. You can restart it from the CPU or handheld monitor.

3. Does the IC660BBS100 work with 230 VAC systems?
   No, its AC voltage range is 93 to 132 VAC. For higher voltages, consider other GE Fanuc blocks.

4. What is a failed switch diagnostic?
   The block compares commanded output state against internal switch state. A mismatch triggers this diagnostic message.
