The Foxboro P0926HT is a Time Strobe/GPS Master Module designed for the Foxboro I/A Series Distributed Control System (DCS). This module plays a critical role in maintaining system-wide time synchronization, which is essential for accurate event sequencing, data logging, and process control. It receives precise time signals from either an Inter-Range Instrumentation Group (IRIG-B) time source or a Global Positioning System (GPS) receiver. The P0926HT then distributes this synchronized time signal to the control processors on the baseplate, ensuring that all components within the control network operate on a unified and accurate timeline. Its robust design makes it a reliable solution for demanding industrial environments where precise timing is paramount.
