SST-PB3-CLX PROFIBUS DP Communication Module

SST-PB3-CLX is a PROFIBUS DP scanner module developed by Molex SST for Rockwell ControlLogix PLC chassis. It enables ControlLogix controllers to communicate with PROFIBUS DP slave devices in industrial process automation systems.

This module plugs directly into the ControlLogix backplane, with on-board co-processor handling PROFIBUS protocol independently. It supports high-speed cyclic data exchange and comprehensive bus diagnostics. It is widely used as spare replacement part for factory automation control cabinet maintenance and retrofit projects.
