Product Description

The P0928EB is a CP280 Control Processor for Foxboro I/A Series / Evo systems. It serves as the primary computational engine, executing advanced control logic, managing high-density I/O, and maintaining deterministic communication across the plant network.

Built on a rugged PowerPC architecture with enhanced memory and dual Ethernet ports, the P0928EB handles up to 256 Fieldbus Modules (FBMs) and 8,000 control blocks, supporting complex PID loops, sequencing, and interlocking logic. It is ideal for mission-critical, high-availability applications in large-scale process plants.
