The GE IC660TBA101 is a Terminal Base Assembly engineered to provide a reliable field wiring interface for discrete input signals within GE Fanuc Genius I/O distributed automation systems. Designed to organize and secure connections from field sensors and switches, it serves as the physical link between field cabling and the corresponding discrete input electronics assembly.
By separating field terminations from electronics, the IC660TBA101 enhances wiring integrity, simplifies installation, and supports efficient maintenance practices in industrial environments.

Field Wiring and Function
The IC660TBA101 provides a central point for terminating field-level discrete input wiring — including sensors, switches, and contact closures — using rugged screw-clamp terminals. From there, the signals are routed via the terminal base into the corresponding discrete input electronics assembly (such as IC660EBA101), streamlining wiring and reducing potential noise or connection errors.
This modular design allows field technicians to:
-
Perform rapid field terminations
-
Organize wiring clearly and logically
-
Replace electronics assemblies independently of field wiring
