Description
The ABB TU818 3BSE069209R1 is a 32-channel, 50V Compact Module Termination Unit (MTU) designed for the ABB S800 I/O system. This passive unit serves as the critical interface between field wiring and I/O modules, providing reliable signal transmission and power distribution. It features a compact design with 40-pole screw terminals and supports DIN rail mounting in both horizontal and vertical orientations. The MTU incorporates part of the ModuleBus, distributing signals to the I/O module and the next MTU in the chain. It utilizes mechanical keying with 36 possible configurations to prevent incorrect module insertion and ensure system integrity.
