Overview

The ABB TU842 3BSE020850R1 Redundant Module Termination Unit is engineered for industrial automation systems, supporting up to 16 I/O channels and 2+2 process voltage connections. With a robust design that caters to high performance, this unit offers a maximum rated voltage of 50V and a current capacity of 3A per channel, making it suitable for demanding environments where reliability is crucial.

Functional Highlights

This Redundant Module Termination Unit effectively distributes two ModuleBuses—one to each I/O module and the subsequent MTU—ensuring seamless data flow throughout the system. By shifting outgoing position signals, the TU842 generates the correct addresses for each I/O module, facilitating smooth communication and synchronization across the network.

Additionally, the TU842 is designed for ease of installation. It can be mounted on a standard DIN rail and features a mechanical latch that secures the unit firmly in place. To accommodate various I/O module types, the TU842 includes four mechanical keys, offering up to 36 different configuration possibilities. This setup does not interfere with the functionality of the MTU or connected I/O modules, ensuring optimal operation in a variety of applications.
