Emerson 5X00481G01 OCR1100 DCS main controller, early hardware revision supporting redundant bumpless switchover, executes PID and interlock logic, critical Ovation spare for power plants.

Product Overview

• Part No: 5X00481G01
• Brand: EMERSON / Westinghouse Ovation

• Category: OCR1100 Process Controller 5X00481G01 is the early hardware revision of OCR1100 main process controller for Emerson Ovation distributed control system. It acts as core computing unit executing PID closed-loop regulation, boolean logic, sequential control and safety interlock algorithms. This controller supports 1:1 redundant hot standby configuration with bumpless automatic failover 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 provide connections to operator stations, historians and third-party devices. Fanless low-power design guarantees stable long-term continuous operation. Built-in comprehensive self-diagnostics monitor hardware, memory and communication links. Front panel LED indicators display operation status, network activity and fault alarms. This version can be replaced by upgraded revision 5X00481G04 with matched Ovation firmware. It serves as essential maintenance spare for thermal power plants and combined-cycle facilities.
