Description
The GE IS220PRTDH1A is a Resistance Temperature Device (RTD) Input Module designed for the GE Mark VIe Speedtronic turbine control system. It is an I/O Pack module used to acquire temperature signals from RTD sensors and transmit processed temperature data to the Mark VIe controller through the industrial Ethernet I/O network.
The IS220PRTDH1A works with compatible RTD terminal boards such as IS200TRTDH2D, IS200SRTDH1A, and IS200SRTDH2A. It provides accurate temperature monitoring for turbine bearings, windings, exhaust systems, and auxiliary equipment in gas turbine, steam turbine, and power generation applications.
This module integrates an acquisition circuit and shared Mark VIe processor architecture, supporting reliable field temperature measurement, diagnostics, and communication within distributed control systems.
