The GE IC660TBA105 is a Terminal Base Assembly designed to provide a secure and organized wiring interface for discrete input and output signals in GE Fanuc Genius I/O distributed automation systems. It serves as the physical connection point for field devices — such as sensors, switches, relays, and indicators — allowing straightforward terminations and routing into the associated electronics assemblies.
By separating field connections from the electronics layer, the IC660TBA105 simplifies installation, improves serviceability, and helps maintain signal integrity in industrial environments.

Field Wiring and Functional Role
The IC660TBA105 provides a convenient and robust point for connecting discrete field signals, including:
-
Switches and pushbuttons
-
Proximity and limit sensors
-
Relay contacts
-
Indicator outputs
Field leads are secured to screw-clamp terminals, then routed through the terminal base to the discrete input/output electronics assemblies (such as IC660EBA105 for inputs or IC660EBD025 for outputs).
This separation enables:
-
Simplified field wiring organization
-
Reduced risk of noise and connection faults
-
Fast electronics access without disturbing field terminations
