Emerson 5X00226G02 OCR1100 DCS controller, mid-version hardware supporting redundant bumpless failover, executes PID and interlock logic, key Ovation spare for power plants.

Product Overview

• Part No: 5X00226G02
• Brand: EMERSON / Westinghouse Ovation

• Category: OCR1100 Process Controller 5X00226G02 is the mid hardware revision of OCR1100 main controller for Emerson Ovation distributed control system. It acts as core processing unit to run PID closed-loop regulation, boolean logic, sequential control and safety interlock algorithms. The controller supports 1:1 redundant hot standby with bumpless automatic switchover upon primary unit failure. It is compatible with local Ovation I/O branches, Q-Line I/O and remote I/O nodes. Multiple Ethernet ports connect operator stations, historians and third-party systems. Fanless low-power architecture ensures long-term stable operation. Built-in self-diagnostics continuously monitor hardware, memory and communication links. Front panel LEDs display operation status, network activity and fault alarms. This revision can be replaced by upgraded 5X00226G04 with matched system firmware. It serves as essential maintenance spare for thermal power and combined-cycle power plants.
