Product Details:

FOXBORO CP100 is a rack-mounted field control processor for FOXBORO I/A Series DCS platform, a high-performance DCS CPU module built for process automation. This processor module adopts conformal coated PCB assembly and reinforced shielding frame, protecting internal microprocessor, memory and bus circuits from vibration, dust and electromagnetic interference inside industrial control cabinets. It can be plugged directly onto the DCS rack backplane and matched with dedicated terminal base for fast installation and convenient maintenance. It serves as the core control unit to execute PID closed-loop control, safety interlock and user sequence control programs.

This FOXBORO CP100 DCS CPU module collects analog and discrete process signals from FBM I/O modules. It calculates process deviations and generates control commands to drive valve positioners and field switching equipment, stabilizing temperature, pressure, flow and liquid level parameters. It supports bidirectional high-speed bus communication with operator workstations and other system modules, for real-time process monitoring, historical data recording and alarm management. Built-in continuous self-diagnosis function monitors memory, bus connection and hardware health. It triggers alarm output once detecting hardware failure or communication interruption, helping maintenance engineers quickly locate faults and reduce unplanned plant downtime. It supports hot swap operation, technicians can replace the module without shutting down the whole DCS system, which is critical for continuous production plants.
