Foxboro FCP270 P0917YZ Field Control Processor

The Foxboro FCP270 P0917YZ is a field control processor for I/A Series DCS systems. It executes continuous control logic, sequence programs and interlock functions, collecting field I/O data and communicating with operator workstations and other control nodes to realize distributed process control.

This rack-mounted processor supports redundant configuration for high system availability. It adopts industrial anti-interference design and conformal coating, widely used as spare parts for maintenance and upgrading of DCS cabinets in petrochemical, power and pharmaceutical industries.
