GE IS200TRTDH1DCB（TRTD）是Mark VIe控制系统专用RTD热电阻端子板，集成16路三线制RTD采集通道，输出10mA多路复用激励电流，适配Pt100温度传感器，采集轴承、定子、缸体等点位温度信号，经板卡调理后上传至I/O处理器。

GE IS200TRTDH1DCB (TRTD) is a dedicated RTD terminal board for Mark VIe control system. It integrates 16 three-wire RTD channels and supplies 10mA multiplexed excitation current for Pt100 sensors. It collects temperature signals from bearings, stators and cylinder surfaces, then transmits conditioned data to I/O processors.

板卡自带输入浪涌抑制与高频噪声滤波电路，支持RTD断线、短路故障自动识别隔离，全板喷涂三防漆。属于停产存量备件，多用于联合循环机组汽机、燃机温度监测回路维保，是机组超温保护、热平衡计算的关键采集板卡。

This board is equipped with surge suppression and high-frequency noise filtering circuits, and can automatically detect and isolate open or shorted RTD channels. Full-board conformal coating is applied. It is a discontinued legacy spare part widely used for temperature monitoring loop maintenance of gas and steam turbines, critical for over-temperature protection and thermal balance calculation.
