SST SST-PB3M-CPX PROFIBUS DP Master Communication Card – CompactLogix Series
When a PROFIBUS DP network loses its master module, the consequences are immediate and severe: field devices go silent, process data stops flowing, and entire production lines grind to a halt. In industries where every minute of downtime translates directly into lost revenue and compromised safety, the integrity of your PROFIBUS DP master is non-negotiable. The SST-PB3M-CPX communication card is the critical link that keeps your distributed I/O, drives, and intelligent field instruments synchronized with your Allen-Bradley CompactLogix controller — and without it, your automation architecture simply cannot function.
The SST-PB3M-CPX occupies a well-established position within SST’s proven CompactLogix communication card series, purpose-engineered to deliver PROFIBUS DP Class 1 master functionality directly within the CompactLogix backplane. SST (a Woodhead/Molex brand) has long been recognized as a global leader in fieldbus communication solutions, with their PROFIBUS master cards deployed across thousands of industrial sites worldwide — from automotive assembly plants in Germany to petrochemical facilities in the Middle East. This module represents the convergence of Rockwell Automation’s CompactLogix platform reliability with SST’s decades of PROFIBUS protocol expertise.
