IC660BBS102 GE Fanuc Isolated I/O Block 8 Circuits

IC660BBS102 Isolated I/O Block with Failed Switch Diagnostics from GE Fanuc

The IC660BBS102 belongs to the GE Fanuc Genius I/O series. This block delivers 8 circuits across 4 isolated groups. Each group contains two circuits. Continuous isolation withstands 250 VAC or VDC between any group and ground. The same rating applies between any two groups. Transient rating reaches 2000V peak for 10 seconds. This block reports failed switch diagnostics, which sets it apart from some earlier models.

Input Response and Filter Times

Input response time for AC signals equals 2 milliseconds plus the selected filter delay. For DC signals, response time equals 0.8 milliseconds plus filter delay. Selectable input filter times range from 10 ms to 100 ms. Turn-on delay maximum for AC is 0.5 Hz plus 1 ms. For DC, maximum turn-on delay is 1 ms. Maximum switching frequency is once per second. Zero crossing switching applies for both OFF to ON and ON to OFF transitions.

Failed Switch Diagnostic Feature

The IC660BBS102 reports failed switch diagnostics. It compares the block output command against the internal switch state. When a mismatch occurs, the block generates a diagnostic message. This feature helps you identify output circuit problems quickly. Use it for applications where output verification matters. The older IC660BBS100 also reports this diagnostic. However, the IC660BBS101 does not include this feature.

Configurable Features

You can configure several features on the IC660BBS102. Select AC or DC circuit voltage for each group. Set defaults for output power-up behavior. Choose CPU redundancy to maintain operation during processor faults. Select input filter times from 10 ms to 100 ms. Enable output pulse test capability for verification. Turn on module control for bus switching. These options give you flexibility across different applications.

LED Status Indicators

The IC660BBS102 includes multiple LEDs for status monitoring. A Unit OK LED shows overall block health. An I/O Enabled LED indicates communication status. Circuit LEDs sit on the logic side of each switch. These LEDs help you verify operation without additional tools. Use them during commissioning and troubleshooting.

Environmental and Mechanical Ratings

The IC660BBS102 operates between 0°C and 60°C. Storage temperature ranges from -40°C to 100°C. Dimensions measure 8.83 x 3.50 x 3.94 inches (HxWxD). Weight equals approximately 4 pounds or 1.8 kg. Peak heat dissipation reaches 45.6 Watts when all 8 outputs are on at 2 Amps each. Consider this thermal output when designing your enclosure.

Mounting and Installation Guidelines

This Genius I/O block is considered open equipment. You must install it inside a protective enclosure. The enclosure should stay clean and free from airborne contaminants. Adequate cooling airflow is necessary for proper operation. You can mount the IC660BBS102 right side up or upside down. Leave at least 2 inches of space between adjacent blocks. Do not use mounting screws as the only means of grounding the block. Provide a separate ground connection for safety.

Network Topology and Communication

The IC660BBS102 supports the Genius I/O protocol. You can connect it in a multi-drop or daisy chain topology. A network of Genius I/O capable devices can share the same bus. The block communicates directly with any GE Fanuc bus controller, including PCIM or QBIM models. Redundant processors are also supported. The block can hold the last output state during communication loss.

Wiring and Terminal Information

Each terminal block accepts one AWG #12 wire. It also accepts two AWG #14 wires. Terminals labeled 1 through 4 accommodate ring terminals up to 0.27 inches wide. Recommended torque for all terminals is 6 inches per pound. The IC660BBS102 works as long as terminals 5 and 6 receive power. You can connect multiple power sources as needed.

Compatibility Information

The IC660BBS102 works fully with handheld monitor IC660HHM501. It works with any GE Fanuc bus controller. Backward compatible blocks include IC660CBS100, IC660BBS100, and IC660BBS101. Note that terminal assembly model IC66*TSS100E is not compatible with earlier block versions. The IC660BBS102 replaces the older IC660BBS100 model. Both report failed switch diagnostics.

Application Examples

Use the IC660BBS102 where output verification matters. Failed switch diagnostics help you detect relay or contactor problems. Mixed I/O applications benefit from its flexible configuration. Systems with both AC and DC devices can use its dual voltage support. Applications requiring bus switching or CPU redundancy will find this block suitable.

FAQ

1. What is the difference between IC660BBS102 and IC660BBS101?
   The IC660BBS102 reports failed switch diagnostics. The IC660BBS101 does not. The IC660BBS102 also replaces the older IC660BBS100 model.

2. Does the IC660BBS102 support both AC and DC on the same block?
   Yes, each group supports either AC or DC. You can mix groups with different voltage types on the same block.

3. How fast does the short circuit protection respond?
   Electronic fusing shuts down a shorted output within 5 microseconds. This protects the block from damage.

4. Can I mount the IC660BBS102 upside down?
   Yes, you can mount it right side up or upside down. Leave at least 2 inches of space between blocks for cooling.
