The GE IC660TBD022 is a Discrete Output Terminal Base Assembly designed to serve as the field wiring interface for discrete output devices within GE Fanuc Genius I/O distributed automation networks. This module provides a secure and clearly organized termination point for field wiring, routing signals from outputs such as relays, contactors, and indicator devices into the associated electronics assembly.
By separating field terminations from sensitive electronics, the IC660TBD022 supports faster troubleshooting, minimizes wiring errors, and enhances overall reliability in industrial control systems.

Field Wiring Function
The IC660TBD022 terminal base provides termination points for field devices that are activated by discrete output channels, including:
-
Solenoids and actuators
-
Relay coils and contactor inputs
-
Alarm lamps and status indicators
-
Motor control feedback
-
General purpose discrete outputs
Each field conductor is secured in place using robust screw-clamp terminals, which then route the signals through the terminal base to the corresponding discrete output electronics assembly (such as IC660EBD022). This configuration creates a clear separation between field wiring and the electronics layer, improving both maintainability and signal quality.
