P0902BM
Product Name
P0902BMFoxboro (Schneider Electric) 8-Channel Isolated Digital Output Module
Model Interpretation:
- “P0902BM”: Follows Foxboro’s I/A Series part number convention—”P” denotes I/O peripheral module, “0902” specifies the 8-channel isolated output configuration, and “BM” indicates compatibility with the I/A Series DCS backplane ecosystem .
- The designation aligns with Foxboro’s legacy naming for digital I/O modules, where numeric segments encode channel count and isolation type, and suffixes confirm system integration.
2. Product Description
The P0902BM is an industrial-grade isolated digital output module engineered by Foxboro for reliable control signal distribution in I/A Series Distributed Control Systems (DCS) across oil & gas, chemical processing, power generation, and water treatment industries . As a critical link between DCS controllers and field actuators, its core functions include:
- Converting low-voltage logic signals from the DCS controller into 8 independent, galvanically isolated output signals (24V DC typical) to drive valves, relays, and motor starters .
- Preventing cross-channel interference and ground loops via channel-to-channel isolation, ensuring signal integrity in noisy industrial environments with long wiring
