Product function

GE IS220PRTDH1A Resistance Temperature Device Input Module, linearizes, and digitizes RTD sensor signals, providing high-accuracy temperature feedback over the IONet Ethernet bus to the Mark VIe CPU. Ensures rapid, reliable temperature data for control loops, safety interlocks, and trending without user-level configuration.
