ABB CP800 Symphony Plus DCS Control Processor Module

CP800 is a mid‑range control processor module for ABB Symphony Plus SD‑series DCS system. It executes process control logic, PID regulation and function‑block computation, serving as the main processing unit for medium‑scale distributed control applications in process industries.

This hot‑swappable DIN‑rail module supports controller redundancy for bumpless master‑standby switchover. It cooperates with SD‑series I/O modules and communication cards such as PDP800, widely deployed in power auxiliary systems, water‑treatment and chemical‑process automation cabinets.
