Product Overview
The 1794-TB3GK is an Allen-Bradley FLEX I/O, FLEX Ex, FLEX XT terminal base offering a 3-wire grounded screw-clamp connection with conformal coating. It serves as the physical interface between FLEX I/O modules and the FlexBus communication backplane, supporting module mounting and power distribution in industrial control systems. It is designed for installations exposed to corrosive or humid environments (ISA/ANSI-71.040 Class G3). Typical use cases include hazardous-rated applications, process control racks, and distributed I/O stations requiring reliable field termination.
Best Suited For
- FLEX I/O systems requiring grounded 3-wire screw-clamp termination
- Environments with corrosive gases or humidity (Class G3)
- Distributed I/O architectures using FLEX Ex or FLEX XT platforms
- Replacement or upgrade of conformal-coated terminal bases
- Control panels requiring DIN-rail mounted FLEX backplane integration
