Emerson 5X00226G04 OCR1100 process controller for Ovation DCS, fanless industrial processor supporting redundant bumpless failover, executes PID regulation, sequence control and interlock logic, compatible with local and remote I/O, critical spare for power generation automation systems.

Product Overview

• Part No: 5X00226G04
• Brand: EMERSON / Westinghouse Ovation

• Category: OCR1100 Process Controller 5X00226G04 is the OCR1100 series main process controller within Emerson Ovation distributed control system. It acts as core computing unit responsible for running continuous PID control, boolean logic, sequential control, safety interlock and advanced control algorithms. This controller supports 1:1 redundant hot standby configuration to achieve bumpless automatic switchover upon primary unit failure and enhance system availability. It supports Ovation local I/O branches, Q-Line I/O and remote I/O nodes to deliver flexible I/O expansion schemes for medium and large-scale control applications. Multiple Ethernet communication ports provide connections to operator workstations, historians and third-party peripheral systems. The unit adopts fanless low-power architecture to extend service life and reduce maintenance frequency. Built-in comprehensive self-diagnosis continuously monitors hardware health, memory status and communication links. Front panel LED indicators display operation status, network activity and fault alarms for convenient field inspection. It serves as essential maintenance spare for thermal power plants, combined-cycle facilities and petrochemical process control platforms, supporting migration projects replacing legacy OCR400 controllers.
