ALSTOM VP32502X是ALSPA控制系统单板处理器主板，替代标识PIB102A，采用VME总线架构，为阿尔斯通汽轮发电机组控制系统提供核心运算能力。板卡为插箱式背板安装，工业加固PCB设计，适配电站控制柜多粉尘、振动工况。

ALSTOM VP32502X is single board processor motherboard of ALSPA control system, also known as PIB102A. It is built on VME bus architecture and acts as the core computing unit for Alstom turbine and generator control systems. It is designed as plug-in board for backplane rack, with rugged industrial PCB construction to withstand dusty and vibrating environment in power control cabinets.

负责实时逻辑运算、模拟量采集、顺控联锁以及背板总线调度管理，完成转速调节、阀位控制、保护跳闸等关键控制算法。该型号早已停产，存量机组维修资源稀缺，是火电、水电汽轮机控制柜维修替换的重要备件。

It executes real-time logic, analog acquisition, sequence interlock and backplane bus management, running critical algorithms for speed regulation, valve position control and trip protection. This model has been discontinued for years and hard to source, serving as essential spare for maintenance of legacy thermal and hydro turbine control cabinets.
