The Allen-Bradley 1794-TB3TS is a high-performance 3-wire spring terminal base designed specifically for Flex I/O architectures. This module provides a reliable, vibration-resistant connection for field wiring, utilizing spring clamp technology to eliminate the need for screwdrivers and reduce maintenance. As a key component in the 1794 series, the 1794-TB3TS ensures secure termination for three-wire devices such as proximity sensors, limit switches, and transmitters. Its compact design and easy snap-on mounting make it an ideal choice for distributed control systems in harsh industrial settings. The terminal base supports up to 16 points of I/O, offering flexibility for both digital and analog signals.
