Product Overview

The IS220PRTDH1B (Model: IS220PRTDH1B) is a high-performance Resistance Temperature Detector (RTD) input module engineered for the GE Mark VIe turbine control system. This specialized PRTD pack serves as the primary interface for precision temperature monitoring across mission-critical turbine components, bearing assemblies, and auxiliary process equipment.

By digitizing low-level resistance signals directly at the source, the IS220PRTDH1B (Part Number: IS220PRTDH1B) eliminates the signal degradation common in long-distance analog wiring. The module features 10 independent channels supporting a wide variety of RTD types (Platinum, Nickel, Copper) and transmits high-resolution data via the IONet Ethernet backbone to the Mark VIe controller. Its 1500 VDC galvanic isolation and superior common-mode rejection make it indispensable for reliable operation in high-interference power generation and oil & gas environments.
