ABB DSBC 173 Repeater Slave

Core Performance & Industrial Application

The ABB DSBC 173 (57310001-KH) is a bus repeater slave module for the Advant OCS / S100 I/O bus network.

It extends and regenerates bus signal segments to maintain reliable data transmission across remote I/O subracks.

It mounts as a plug-in PCB in the control rack and links bus master to distributed slave stations.

It supports segment extension, signal reshaping and bus redundancy where required.

It is used as spare replacement in legacy ABB Advant OCS process control systems.
