Product Function Description

DS200TCTGG1AFF TCTG terminal board is dedicated RTD signal interface for Mark V turbine system. It receives temperature signals from field PT100 RTD sensors, completes signal conditioning and filtering, and sends processed temperature data to main I/O control board. It adopts 3‑wire RTD wiring to minimize measurement error caused by lead resistance. Hardware jumpers support different sensor configurations, LED indicators reflect real‑time channel status. AFF revision improves filter circuit for better noise rejection, delivers accurate temperature data of bearing and cylinder, provides reliable signal basis for unit thermal protection interlock.

Product Details

Rack‑mount multilayer PCB fits inside Mark V cabinet slot, working with matched analog I/O control board. Conformal coating protects circuit against dust, moisture and electromagnetic interference for long‑term plant operation. This original part is end‑of‑life, widely used for unit maintenance and spare‑part replacement. Confirm hardware revision before installation for system compatibility.
