Emerson 5X00226G01 OCR1100 DCS process controller, early hardware revision with redundant bumpless failover, executes PID and interlock logic, key spare for power plant Ovation control system.

Product Overview

• Part No: 5X00226G01
• Brand: EMERSON / Westinghouse Ovation

• Category: OCR1100 Process Controller 5X00226G01 is an early hardware revision of the OCR1100 main process controller within Emerson Ovation distributed control system. It serves as the core processing unit to run 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 improve 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 enable 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. 5X00226G01 can be replaced by upgraded revision 5X00226G04 with compatible system software. It serves as essential maintenance spare for thermal power plants, combined-cycle facilities and petrochemical process control platforms.
