IC660BSM021
GE
Overview
The IC660BSM021 is an automation component from GE. The IC660BSM021 is a Genius I/O Bus Switching Module (BSM) used to connect input/output devices to two serial buses simultaneously. IC660BSM021 exists in two ve.
Application & Technical Notes
As an automation component, the IC660BSM021 is intended for deployment in panel-based control cabinets and machine enclosures where the GE product portfolio equipment is installed. It performs a defined automation function within the control system and is selected to match the installed GE platform.
Key published characteristics include a 18 to 56 Volts DC rating. These values should be confirmed against the current manufacturer datasheet before final selection, as options and suffixes vary by configuration.
Maintenance & Diagnostics
Inspect terminals and connectors for corrosion or looseness, and confirm the module seats correctly in its carrier. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.
Sourcing & Procurement
When sourcing the IC660BSM021, distinguish three supply tiers: (1) genuine GE stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.
Confirm mechanical and electrical compatibility with your GE product portfolio installation and the intended function. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.

Specifications
The IC660BSM021 is a Genius I/O Bus Switching Module (BSM) used to connect input/output devices to two serial buses simultaneously. IC660BSM021 exists in two versions, the 115 VAC/125 VDC BSM catalogued as IC660BSM120 and the 24/48 VDC BSM catalogued as IC660BSM021. Version IC660BSM021 BSM is capable of connecting a maximum of eight discrete and analog blocks to a dual bus. Version IC660BSM021 is also capable of permitting up to 30 I/O blocks to interface to the same dual bus if additional BSMs are used. This type of dual bus configuration provides a backup communications path that can be used in case of bus failure. Each bus from the dual bus pair is coupled with a bus controller or PCIM. The system may also support CPU redundancy if each bus interface module is residing in a different CPU. The phase B discrete block in the cluster controls all operations of IC660BSM021. The first circuit an output dedicated to the IC660BSM021 BSM. This particular output makes it possible to switch buses every time communication is lost on the current bus. If an operational bus cannot be found with one switch of the IC660BSM021, the BSM must then wait for communication to be restored on the connected bus, or until power can be cycled to the BSM controller block. This prevents unnecessary switching. De-energized, the IC660BSM021 connects the blocks to bus A. IC660BSM021 BSM becomes energized only when selection of bus B is required. The LED on the IC660BSM021 is lit when bus B is active. IC660BSM021 BSM can also be commanded to switch buses using the CPU or handheld monitor. IC660BSM021 and IC660BSM120 are identical except for power source. IC660BSM021 is powered by 24/48VDC, while IC660BSM120 is powered by 115 VAC/l25 VDC. The GE Fanuc IC660BSM021 Genius I/O Bus Switching Module (BSM) is for the Genius I/O Bus System. This module has 2 serial connectors and 24/48 Volts DC operating voltage, and it can accommodate up to 8 I/O blocks on the same dual serial bus.
