The G
E IC670CHS002 is an I/O terminal block designed for GE Field Control and VersaMax-style distributed I/O systems. It serves as a mechanical and electrical mounting base for up to two I/O modules, providing secure field wiring termination, backplane communication routing, and hot-swap module replacement capability.
In industrial automation systems, this component is not a “signal processor” itself, but a critical infrastructure layer that ensures reliable connection between field devices and control modules while minimizing downtime during maintenance.

System Role & Functional Behavior
The IC670CHS002 functions as the structural and electrical foundation of the I/O station:
- Provides mounting base for two independent I/O modules
- Enables secure screw-terminal field wiring connections
- Routes backplane communication between modules and BIU (Bus Interface Unit)
- Allows hot-swapping of I/O modules without disconnecting field wiring
- Organizes power and signal terminals into isolated groups (A, B, E)
- Reduces downtime during maintenance or module replacement
This makes it a key “physical backbone” component in GE distributed control systems.
