Description
1. Product Description
The GE IS220PRTDH1BC, associated with part number 336A5026ADP13, is a Resistance Temperature Detector (RTD) input module for GE Speedtronic Mark VIe turbine control systems. It acquires temperature signals from compatible RTD sensors and passes the processed measurements to the control system for equipment monitoring, alarms, and control functions. Typical applications include gas and steam turbines, generators, bearings, and lubrication systems. The module is designed to work with a compatible RTD terminal board. Confirm the complete model suffix, terminal board pairing, and system revision before replacement.
