Product Details

The IS200SRTDH2ACB is RTD input terminal board for GE Mark VI Speedtronic turbine control system.

This board is installed inside turbine control cabinet, connected with field RTD temperature sensors through terminal blocks. It supports multiple wiring modes such as 2‑wire,3‑wire and 4‑wire, and can collect temperature signals of turbine bearing, casing, inlet and exhaust parts. It transfers resistance signals to the rear‑stage I/O processing board for conversion and calculation, providing accurate temperature process data for turbine thermal monitoring, protection and control logic.

It supports open‑circuit and short‑circuit diagnosis of each channel, and can upload fault alarm information to the turbine controller. The board adopts conformal coating process, which has good anti‑interference performance and adapts to harsh electromagnetic environment of power‑plant turbine site.

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

It is important spare hardware for temperature signal acquisition loop debugging and defective IS200SRTDH2ACB board replacement.
