GE IS220PRTDH1B is an RTD (Resistance Temperature Detector) Input Module for the GE Mark VIe turbine control system. It interfaces with RTD sensors to measure the temperature of turbine components, bearings, and auxiliary equipment. The module digitizes RTD signals and transmits them via Ethernet to the Mark VIe controller for real-time monitoring and protection. Designed for high-density, mission-critical industrial applications, it ensures accurate, reliable, and safe temperature measurement in power generation, oil & gas, marine propulsion, and heavy industrial systems.
