SST‑PFB3‑VME PROFIBUS‑DP VME Bus Communication Interface Module

SST‑PFB3‑VME is a VME‑bus based PROFIBUS‑DP communication interface module manufactured by Woodhead SST. It bridges VME‑bus host system and PROFIBUS‑DP field bus, realizing high‑speed cyclic and acyclic data exchange between VME‑based controller and PROFIBUS‑DP slave field devices.

This VME slot‑mount board is equipped with dual DB9 PROFIBUS‑DP interfaces and status LED indicators, supporting maximum 12Mbps baud rate. Widely used as spare replacement parts for power, metallurgy and petrochemical industry VME‑based control cabinet maintenance and retrofit projects.
