Product Details

The IS230SRTDH2A is SMX series DIN‑rail type RTD terminal board for GE Mark VIe Speedtronic turbine control system.

This module adopts compact DIN‑rail installation structure, equipped with high‑density euro‑style terminal blocks for field RTD sensor wiring. It supports multiple wiring modes for various thermal resistance sensors, collects temperature signals of turbine bearings, casings, pipelines and other key positions. After isolation and filtering processing, valid temperature data is sent to rear‑stage PRTD or VRTD I/O processor for conversion and calculation, providing accurate temperature data for turbine monitoring and protection logic.

Built‑in channel diagnosis function, capable of detecting sensor open‑circuit, short‑circuit and signal abnormality, and upload fault alarm information to turbine controller. Conformal coated circuit board improves anti‑interference capability, adapts to harsh electromagnetic environment of power‑plant turbine site.

It belongs to key spare‑part for Mark VIe turbine control system maintenance, widely used in overhaul and renovation projects of gas‑steam turbine generating units.

It is important spare hardware for turbine temperature measuring loop debugging and defective IS230SRTDH2A module replacement.
