CAMERON AAP3798102-00131是Cameron Cooper Maestro控制系统配套MU单元I/O板卡，适配TA、MSG系列离心空压机，安装在主控背板上，采集现场温度、压力、振动、开关量传感器信号并隔离上传给主控。

CAMERON AAP3798102-00131 is the MU unit I/O board for Cameron Cooper Maestro control system. It is compatible with TA and MSG centrifugal compressors, mounted on the controller backplane to collect isolated temperature, pressure, vibration and digital signals from field sensors to the main controller.

板卡自带光电隔离、过压过流保护，通道指示灯方便故障定位，背板总线和Maestro主控通讯，是空压机机组大修、信号采集异常故障替换的核心备件。

It features optical isolation and overvoltage/overcurrent protection with channel LED indicators for fast troubleshooting. It communicates with Maestro CPU via backplane bus and serves as critical spare for compressor overhaul and signal acquisition fault replacement.
