ABB TU842 Redundant Module Termination Unit (MTU)

General Information
The ABB TU842 (part number 3BSE020850R1) is a Redundant Module Termination Unit (MTU) designed for high-availability industrial automation systems. It is part of ABB's System 800xA series, offering a robust and reliable solution for process control, ensuring continuous operation even during component failures.

Technical Specifications

Key Features and Function

• Redundant Design: The TU842 is engineered with a redundant architecture, ensuring that the electrical connection between process I/O and the control system remains intact, even in the case of a failure. This redundancy ensures high availability for critical industrial processes.

• Hot-Swapping Capability: The module allows for hot-swapping, enabling maintenance or module replacement without having to shut down the entire system. This minimizes downtime and enhances operational continuity.

• Continuous Operation: Ideal for applications where reliability and uptime are critical, such as in manufacturing, power generation, or other industrial automation systems.
