Product Overview
The IS200SRTDH2A is a compact DIN-rail RTD terminal board from General Electric’s Mark VIe series. This board provides eight RTD inputs for precise temperature sensing. It connects to PRTD or VRTD I/O processors via high-density Euro-block terminals. The on-board ID chip enables easy system diagnostics. This board is a reliable choice for turbine control and industrial temperature monitoring.
