Overview
The ABB TU843 Module Termination Unit (MTU) is engineered to interface between the field wiring and the I/O modules of ABB’s AC 800M control system. It is part of the S800 I/O family, known for its flexibility, modularity, and high availability, making it ideal for redundant analog and digital I/O configurations in process automation.
Designed for vertical DIN rail mounting, the TU843 simplifies installation in compact control cabinets. The unit supports hot-swappable I/O modules, allowing system upgrades and maintenance without the need for system downtime. Its redundancy optimization ensures continuous operation, even in the event of a failure of one I/O module.
This MTU features robust signal integrity, secure terminal connections, and clear labeling, making it ideal for mission-critical applications in industries like oil & gas, power generation, and chemical processing.
