GE
Overview
The IC660BSM120 is an automation component from GE. The IC660BSM120 Bus Switching Module uses a phase B discrete block in the cluster to control all major operations. The first circuit of this discrete block is a.
Application & Technical Notes
As an automation component, the IC660BSM120 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 90 to 130 Volts AC/95 to 150 Volts DC rating, an operating temperature range of 0 to 60 Degrees Celsius. These values should be confirmed against the current manufacturer datasheet before final selection, as options and suffixes vary by configuration.
Maintenance & Diagnostics
Respect the published operating temperature window (0 to 60 Degrees Celsius); do not exceed it during commissioning or in enclosed panels without airflow. 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 IC660BSM120, 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 IC660BSM120 is a Genius I/O system Bus Switching module used to link I/O devices to two serial buses simultaneously. IC660BSM120 exists in two variations: the 115 VAC/125 VDC BSM catalogued as IC660BSM120 and the 24/48 VDC BSM catalogued as IC660BSM021. IC660BSM120 BSM links up to eight discrete analog blocks to a dual bus. However, when additional BSMs are used, up to 30 I/O blocks can interface with the same dual bus. In case of a bus failure, this dual bus configuration is used to offer a communication backup path to be used. Every bus in the pair is connected to an interface module (Bus Controller or PCIM). CPU idleness can be supported by the system should there be a bus interface module exit in a different CPU. The IC660BSM120 Bus Switching Module uses a phase B discrete block in the cluster to control all major operations. The first circuit of this discrete block is an output devoted to the IC660BSM120 BSM. This output allows the IC660BSM120 BSM to switch buses if communications are lost on the current bus. If one switch of a BSM cannot trace an active bus, the BSM has to wait until the connected bus communication is reestablished. This cuts interchanging by the BSM when no communication is available. The now de-energized IC660BSM120BSM connects the blocks to bus A. IC660BSM120BSM is energized only when a selection of bus B is required. An LED on the BSM only lights up when bus B is active. IC660BSM120 can be commanded to switch buses by either the CPU or a handheld monitor. Note: IC660BSM120 and IC660BSM021 are identical in every aspect apart from the power source. IC660BSM021 is powered by 24/48 VDC, while IC660BSM120 is powered by 115 VAC/l25 VDC. The GE Fanuc IC660BSM120 Genius I/O Bus Switching Module is made for the Genius I/O Bus System. This module has 2 serial connectors and it can accommodate up to 8 I/O blocks on the same dual serial bus. Technical specifications for IC660BSM120 Brand GE Fanuc Series Genius I-O
