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.

Technical Specifications

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.
