Emerson 5X00481G04 OCR1100 controller for Ovation DCS, high-performance main processor supporting redundant bumpless failover, executes continuous control, sequence logic and interlock algorithms, compatible with local and remote I/O, critical spare for power plant and process automation systems.

Product Overview

• Part No: 5X00481G04
• Brand: EMERSON / Westinghouse Ovation

• Category: OCR1100 Process Controller Module 5X00481G04 is the OCR1100 high-performance process controller within Emerson Ovation distributed control system, serving as the core processing unit for executing PID regulation, sequential control, safety interlock and advanced control strategies. It supports 1:1 redundant configuration to realize seamless bumpless switchover upon primary controller failure, maximizing system operational availability. The controller supports local Ovation I/O branches, Q-Line I/O and remote I/O nodes, offering flexible expansion architecture for medium and large-scale control applications. Multiple Ethernet communication ports enable connection to operator stations, historians and third-party systems. Comprehensive onboard diagnostics monitor hardware status, communication links and memory performance continuously. Front panel LED indicators display running state, network activity and fault alarms for convenient on-site inspection. It serves as essential maintenance spare for thermal power, combined-cycle and petrochemical process control platforms and provides backward compatibility for legacy OCR400 controller migration projects.
