The GE Fanuc IC660BSM021 Bus Switching Module (BSM) is a dual bus switching module designed to connect the Genius I/O block devices to dual serial busses simultaneously. This module belongs to the GE Fanuc Genius I/O family, and it offers a reliable serial bus connection and it can provide a backup communication path if there is a bus failure. The IC660BSM021 Bus Switching Module can support connection to a maximum of 8 discrete and analog I/O blocks on a single serial bus, and if the application requires more blocks to be connected, additional BSM modules can the installed to expand the maximum number of blocks to 30 Genius I/O blocks. The IC660BSM021 Bus Switching Module's functions are controlled by a Genius I/O block in the cluster configuration, and it is configured with a handheld monitor or CPU programming.
The GE Fanuc IC660BSM021 Bus Switching Module can be configured to switch between the 2 busses (Bus A or B) by using the handheld monitor or the CPU. When Bus A is activated, the IC660BSM021 Bus Switching Module operates with a voltage rating that is less than 4 Volts DC and a maximum current draw of 10.0 milliamps at 24.0 Volts DC and 30.0 milliamps at 48 Volts DC. It operates at 18 Volts DC to 50 Volts DC when the Bus B is activated. The IC660BSM021 Bus Switching Module has a minimum reliability rating of 500,000 operations and a switch activation time of fewer than 20 milliseconds. The IC660BSM120 Bus Switching Module is supplied as a factory assembly comprising a 24/48 Volts DC bus switching module, three 15-inch prefabricated cables, and a Genius I/O system user manual.
