Product Description
The ABB TU812V1 (3BSE013232R1) is a compact Module Termination Unit (MTU) engineered for the ABB S800 I/O system, part of the System 800xA automation platform. It functions as a passive interface for connecting field wiring to I/O modules and distributing ModuleBus signals within the system.
The TU812V1 supports 16 signal connections through a 25-pin D-sub connector, allowing efficient and organized wiring in industrial environments. It includes mechanical keying to prevent incorrect module insertion, and it automatically shifts position signals to the next MTU, ensuring proper addressing of connected I/O modules.
Built with industrial reliability, the TU812V1 offers a rated insulation voltage of 50 V, 2 A per channel, and 5 A total process connection current. It is DIN-rail mountable, compact, and certified for use in hazardous areas, including ATEX Zone 2 and Class I, Division 2 environments, making it a trusted choice for process automation, power generation, and manufacturing systems.
