Product Description

Allen-Bradley 1794-TB3 FLEX I/O Terminal Base for 16-Point Modules

The Allen-Bradley 1794-TB3 is a FLEX I/O terminal base unit designed to terminate field wiring and support FLEX I/O modules within a DIN-rail mounted distributed I/O system. It provides mechanical retention, electrical connectivity, and FLEXBUS backplane continuity between the adapter and installed modules.

Screw-Clamp Terminal Architecture for FLEX I/O

  • Sixteen dedicated I/O terminals for signal wiring
  • Eighteen common terminals and eighteen voltage terminals
  • Screw-clamp connections for secure conductor retention
  • Daisy-chain capable voltage and common terminals

Integrated FLEXBUS and Power Distribution Design

The 1794-TB3 forms part of the FLEX I/O backplane, delivering 5V DC FLEXBUS power while isolating field wiring from the internal bus. Its terminal layout supports three-wire input devices and output modules while maintaining organized power distribution.

Industrial FLEX I/O Applications

  • Distributed I/O panels using Allen-Bradley FLEX I/O
  • Machine control systems with DIN-rail mounted I/O
  • Industrial automation requiring modular field wiring
