1794-TB3K Functional Description

The 1794-TB3K FLEX I/O Allen-Bradley serves as a fundamental interconnection component within the FLEX I/O system, providing both mechanical mounting and electrical termination for various I/O modules. This terminal base unit features a comprehensive wiring architecture with sixteen dedicated I/O terminals, eighteen common terminals, and eighteen voltage terminals, creating a robust platform for field device integration. The physical design of the module incorporates DIN rail compatibility and measures 94x94x69mm, offering space-efficient installation while maintaining full accessibility for wiring operations and maintenance activities.

Electrical specifications for the 1794-TB3K Base Unit Allen-Bradley demonstrate robust current-carrying capacity, supporting up to 10A at 125V AC/DC across its terminal blocks while maintaining proper isolation between field wiring and the FLEX bus communication system. The terminal configuration includes clearly designated connections for power distribution, with specific terminals allocated for daisy-chaining power to adjacent modules, enhancing system scalability and simplifying cabinet layout. The screw-clamp terminals of the Base Unit 1794-TB3K Allen-Bradley accommodate 24-16 AWG stranded copper wires and require 0.56-0.79 Nm torque for secure connections, ensuring reliable long-term performance in industrial environments.

Installation methodology for the 1794-TB3K AB Flex I/O Terminal Base Unit follows engineered procedures that begin with angling the unit onto the DIN rail before engaging the locking mechanism, creating a secure mechanical foundation for the complete I/O assembly. The integrated design of the Allen-Bradley 1794-TB3K provides essential conformal coating protection while maintaining an open-style enclosure that requires installation within a protective cabinet according to industrial standards. This balance of accessibility and protection makes the unit suitable for various manufacturing and process applications.

The operational reliability of the Allen-Bradley 1794-TB3K In Stock is verified through multiple certifications including c-UL-us, UL, CSA, and CE markings, with demonstrated performance across temperature ranges from -20 to +70°C. The proven durability of the module, evidenced by its 30G shock resistance and 5G vibration tolerance, establishes this terminal base as a trusted interface solution within the Rockwell Automation ecosystem, providing essential wiring infrastructure for discrete, analog, and specialty I/O modules in control systems worldwide.
