Compact 50 V field termination with 16 signal connections and a 25-pin D-sub interface.
The ABB TU812V1 is a compact module termination unit for the S800 I/O system. ABB specifies 16 signal connections, a 25-pin D-sub connection and a 50 V rating. The passive MTU connects field wiring, distributes ModuleBus to the I/O module and onward to the next MTU, and provides mechanical keying for compatible module selection. It mounts on a DIN rail in either direction. Before replacement, verify article number 3BSE013232R1, I/O module compatibility, connector arrangement, mechanical keying and mounting orientation. Stockoems condition, availability and warranty statements are commercial terms, separate from ABB product data.
