ABB TU830 3BSE008528R1 Extended S800 Module Termination Unit

Description

The TU830 3BSE008528R1 is an extended terminal base designed for applications needing individual signal wire termination. It features three rows of screw terminals, providing 24 termination points for 8-channel modules, with dedicated connections for signals, return paths, and power. This passive component ensures system reliability by avoiding active electronics. It supports hot-swapping for easy module replacement without interrupting the process and includes keying pins to prevent incorrect module insertion. It can be mounted vertically or horizontally on 35mm DIN rails.
