The GE IC660BSM120 Bus Switching Module is a key component in the Genius I/O system, designed to enhance flexibility and reliability in distributed control systems. This module enables two independent I/O bus segments to be switched under user control or automatically based on bus failure conditions. Primarily utilized in redundant systems, the IC660BSM120 allows for automatic transfer to a backup bus without disrupting the system’s operation.

Engineered for industrial environments, it supports harsh conditions while maintaining optimal performance. The module ensures maximum uptime and continuous operation in critical control systems such as process automation, manufacturing, and infrastructure control.

Frequently Asked Questions (FAQ)

1. What does the IC660BSM120 module do?

   It provides automatic or manual switching between two Genius I/O buses in case of failure, enabling system redundancy.

2. Can it be used in hazardous or high-vibration environments?

   Yes, it is designed to operate reliably in industrial-grade conditions including vibration, temperature extremes, and EMI.

3. Is the module hot-swappable?

   No, the IC660BSM120 should be de-energized before replacement to avoid communication faults.

4. How does it detect a bus failure?

   The module monitors bus signal integrity and status and automatically switches to the backup line if necessary.

5. Does it support DIN rail mounting?

   Yes, it supports both DIN rail and panel mounting options.

6. What communication protocol does it support?

   It uses the Genius I/O protocol over a shielded twisted-pair bus.

7. Can it be configured through a handheld programmer?

   Yes, configuration and diagnostics can be accessed via GE Genius handheld or host tools.

8. What is the main benefit of using this module in a control system?

   Improved system reliability through automatic communication path redundancy.

9. What happens if both buses fail?

   The module will indicate the failure via LEDs, and the system may experience communication loss until restored.

10. Is firmware update required?

    No regular firmware updates are required; the unit functions with factory firmware.
