Overview

The ABB TU841 Termination Unit (Part No. 3BSE020848R1) is a passive module designed to connect TB840/TB840A Optical ModuleBus Modems to ABB’s S800 I/O system. Unlike active PLC modules, the TU841 does not perform logic or processing; instead, it ensures secure electrical termination, power supply connections, and cluster address configuration.

It is specifically intended for non‑redundant I/O setups, while the TU840 is used for redundant I/O. The TU841 is widely deployed in ABB 800xA and AC 800M automation platforms, where reliability and ease of installation are critical.
