PROSOFT SST‑PB3‑CLX PROFIBUS DP Communication Module

The SST‑PB3‑CLX is a PROFIBUS DP slave/master communication interface module designed for Allen‑Bradley ControlLogix PLC racks. It connects the ControlLogix backplane to PROFIBUS DP field devices and realizes high‑speed cyclic data exchange between the PLC and distributed field peripherals.

This rack‑mounted module supports standard PROFIBUS DP protocol and comes with configuration software for data mapping and diagnostics. Original production has been discontinued. It is widely stocked as aftermarket spare parts for factory automation, packaging and process production line control cabinet maintenance and network upgrading.
