Description
GE IS230SNRTH2A – RTD Temperature Input Module
GE IS230SNRTH2A is a Resistance Temperature Detector (RTD) input module for GE’s Mark VIe turbine control systems, providing high-accuracy temperature measurement from field sensors in harsh industrial environments. This module supports multiple RTD types including Pt100, Pt1000, Ni120, and Cu10, with 3-wire compensation for lead resistance elimination across 16 channels. It addresses thermal monitoring challenges in turbines by delivering 16-bit resolution, fast scanning rates, and fault detection for open/shorted sensors, ensuring precise control inputs for protection and sequencing logic. The GE IS230SNRTH2A interfaces via Mark VIe Ethernet IONet with terminal boards like STRTDH2A, supporting redundant operation and hot-pluggable diagnostics in power generation cabinets.
