Description
The General Electric IC660BSM021 is a 24/48 VDC Genius I/O Bus Switching Module (BSM) designed to enhance communication reliability in industrial automation systems. It allows Genius I/O blocks to interface with two independent serial buses simultaneously, providing a redundant communication path in the event of a primary bus failure.
Features
- Connects Genius I/O blocks to dual communications cables.
- Supports up to 8 discrete or analog I/O blocks per BSM.
- Scalable system design allows up to 30 I/O blocks on a single dual-bus configuration using multiple BSMs.
- Controlled by a Genius I/O block; can be forced or unforced via CPU or Hand-held Monitor.
- Integrated LED indicator for active bus status.
- Automatic default to Bus A when de-energized.
Applications
- Automotive assembly and painting lines.
- Power generation control systems requiring high availability.
- Water treatment and chemical processing plants.
- Steel and aluminum smelting environments.
- Oil and gas exploration and high-integrity shutdown systems.

Installation Guidelines
- Ensure the system is powered down before installing or removing the BSM.
- Mount the module in a location that allows for adequate ventilation and access to the status LED.
- Use shielded cabling for serial bus connections to minimize EMI interference.
- Verify that the BSM is properly configured via the CPU or Hand-held Monitor before commissioning.
- Ensure proper grounding of the I/O system to maintain signal integrity.
FAQ
What is the primary function of the IC660BSM021?
The IC660BSM021 is used to connect Genius I/O blocks to a dual bus configuration. If one communication bus fails, the BSM allows the system to switch to the backup bus to maintain operational continuity.
How many I/O blocks can one BSM handle?
A single IC660BSM021 module can connect up to eight (8) discrete or analog Genius I/O blocks to a dual bus.
What happens if the module is de-energized?
In its default state, when de-energized, the module automatically connects the I/O blocks to Bus A.
