Description
Product Overview
The GE IS200TRTDH1DCB is a RTD input terminal board designed for GE Speedtronic Mark VI turbine control systems. It acquires temperature signals from 3-wire RTD sensors mounted on gas and steam turbine bearings, generator windings and exhaust components, transmitting conditioned temperature data to matching PRTD I/O packs. Equipped with barrier-type removable terminal strips and built-in surge & high-frequency noise suppression, this board delivers stable temperature measurement in high EMI power plant environments. It is widely used for simplex temperature monitoring and turbine thermal protection as a critical DCS spare component.
