Product Overview

The 1794-TBNF is an Allen-Bradley Flex™ I/O fused terminal base unit used within the Flex I/O 1794 modular platform. It serves as both the mechanical and electrical interface between Flex I/O modules and field wiring, incorporating internal fusing for overload protection. Typical installations include distributed I/O architectures in manufacturing, process control, and machine automation where fused isolation at the terminal level is required. 1794-TBNF supports screw-clamp wiring and integrates into standard DIN-rail mounted Flex I/O assemblies.
