Official Full Name ABB 3BSE013232R1 = TU812V1 Compact Module Termination Unit (MTU), 50V Isolation, 25-Pin D-Sub ConnectorABB Group Official Function Description This compact Module Termination Unit is a base carrier for single-channel S800 I/O signal modules in ABB 800xA DCS systems. It provides physical wiring termination, electrical isolation up to 50V, ModuleBus communication interface, and DIN rail mounting for field I/O modules. It bridges the S800 I/O module’s internal bus to external field wiring via an exposed female 25-pin D-sub port, standardizes signal routing, and supports hot-swap of paired I/O modules without system shutdown. It features mechanical keying to prevent mismatched I/O module installation and integrated grounding latching for EMC compliance in industrial environm
