5X00241G02 High-Performance Processor Module (OCR400) for Emerson Ovation DCS

The 5X00241G02 is the upgraded high-performance rack-mounted CPU processor module of Emerson (ex-Westinghouse) Ovation DCS, serving as the direct successor and enhanced revision of the 5X00241G01 controller module (OCR400 series). It acts as the core computing brain of the control rack, executing closed-loop PID regulation, sequential control logic, safety interlock algorithms, high-precision SOE sequence-of-events recording, I/O bus scheduling and system network data interaction. It supports dual redundant hot backup with bumpless switchover, delivers larger memory capacity, faster computing speed and improved fault diagnosis capability, and can be pin-to-pin directly substituted for G01 version without cabinet modification or wiring rework.
