Description
Product Description
The Foxboro P0902CA is a high-resolution analog input module developed for the Foxboro I/A Series Distributed Control System (DCS). It is primarily designed to acquire multiple 4–20 mA field signals with high precision and strong electrical isolation, making it suitable for critical measurement applications in process industries.
The P0902CA provides 16 fully isolated input channels, enabling stable and interference-resistant signal acquisition from transmitters and sensors. It integrates advanced diagnostics, fast sampling performance, and hot-swappable capability, ensuring continuous operation and simplified maintenance in live systems.
Although alternative supplier listings describe the module as an output interface or baseplate assembly, the 16-channel analog input configuration represents the most technically complete and consistent implementation used in I/A Series systems.
