Product Details:

FOXBORO CP73 is a rack-mounted upgraded high-performance control processor for FOXBORO I/A Series DCS system, a high-performance DCS CPU module built for process automation. This processor module adopts conformal coated PCB assembly and reinforced shielding frame, protecting internal high-speed 32-bit RISC microprocessor, larger expanded memory and multi-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 supporting terminal base for fast installation and convenient maintenance. It supports 1:1 fault-tolerant redundant pairing to achieve seamless failover for heavy-load and critical production control loops.

This FOXBORO CP73 DCS CPU module collects analog and discrete field signals from connected FBM I/O modules. It executes PID regulatory control, safety interlock and sequential control algorithms, outputs high-speed control commands to valve positioners and switching actuators to regulate temperature, pressure, flow and liquid level of process fluid. It is equipped with dual redundant Nodebus, Fieldbus and dual 10/100Mbps Ethernet ports to exchange real-time control data with operator workstations and other system modules, supporting graphic display, large-capacity historical data recording and alarm management. Built-in continuous self-diagnosis function monitors memory, bus link and hardware health status. 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 under redundant configuration, technicians can replace the module without shutting down the whole DCS system, which is critical for continuous production plants.
