ABB TU813 3BSE036714R1 S800 I/O Compact Module Termination Unit

Description

The TU813 3BSE036714R1 is a passive baseplate for 8-channel modules, featuring a 25-pin D-sub connector for efficient, pre-fabricated cabling. Its passive design eliminates active failure points, ensuring a high Mean Time Between Failures (MTBF). The TU813 supports hot-swapping of S800 I/O modules for maintenance without disrupting the process or disconnecting field cables. Integrated mechanical keying prevents incorrect module installation, protecting the ModuleBus and connected equipment from electrical mismatch.
