Product Function Description

DS200TBQCG1AAA TBQC termination board is dedicated analog interface for Mark V RST system. It transfers 4‑20mA transmitter and valve position signals from field devices to main I/O pack with filtering and surge protection, and sends analog control outputs to local actuators. Multiple on‑board jumpers adjust hardware mode for different site conditions. Built‑in voltage‑limiting components absorb electrical surge to protect main controller. AAA revision delivers stable analog signal for turbine regulation and process monitoring loops, serving as vital wiring component for turbine redundant control system.

Product Details

Rack‑mount multilayer PCB fits inside Mark V cabinet slot and must work with matched RST I/O control board. Conformal coating provides protection against dust, moisture and heavy electromagnetic interference for continuous power‑plant operation. This original part is end‑of‑life, widely used for unit maintenance and spare‑part replacement. Check jumper setting and hardware revision before installation for system compatibility.
