Product Overview

The ABB TU849 is a specialized Module Termination Unit (MTU) designed for the ABB S800 I/O system, specifically engineered to support “1oo1” (1 out of 1) architecture configurations. This unit serves as the critical physical interface between the S800 I/O modules and the field wiring, providing a robust and reliable connection point for process signals. The ABB TU849 is particularly valued in applications where a single-channel configuration is required, ensuring that every signal is transmitted with high integrity and minimal electrical noise.

In the context of industrial automation, the “1oo1” designation implies a non-redundant, single-channel system where the reliability of each individual component is paramount. The ABB TU849 is built to meet these rigorous demands, featuring a durable design that protects against environmental stressors such as vibration, dust, and electromagnetic interference. By providing a secure mounting platform on standard DIN rails, the ABB TU849 simplifies the installation of I/O modules while ensuring that the electrical characteristics of the field signals—whether analog or digital—are preserved throughout the control loop.
