Product Overview

• Part No: CMP1838, TRVCO62345000, CP00005202
• Brand: ALSTOM

• Category: CMP1838 Precision Control Processor ModuleCMP1838 TRVCO62345000 CP00005202 is ALSTOM Contronic platform Eurocard plug-in dedicated processor board. The three codes belong to the same hardware assembly:CMP1838 = module type；TRVCO62345000 = drawing part number；CP00005202 = internal factory serial reference number.This module undertakes real-time signal processing, closed-loop regulation algorithm operation and logic calculation in turbine control racks. It collects speed, pressure, valve position analogue signals and digital interlock signals via backplane bus, executes turbine speed control, load adjustment, extraction pressure regulation and protection interlock logic, and outputs drive commands to valve actuator modules. Equipped with on-board self-diagnosis, signal filtering, galvanic isolation and surge protection circuits, it ensures continuous stable operation under strong electromagnetic interference in power plant turbine governing cabinets. It is discontinued original critical maintenance spare widely used for overhaul of thermal power and combined-cycle steam turbine control systems.
