Product Function Description

DS200CTBAG1ADD CTBA terminal board acts as signal interface hub for Mark V turbine system. It connects field sensors and actuators to main I/O control pack, provides signal termination and noise filtering for incoming field signals, and transfers control commands from controller to local devices. Hardware jumpers support different signal mode setup. LED indicators display real‑time channel status. ADD revision optimizes signal circuit for better surge and noise immunity, ensuring reliable signal transmission for turbine regulation and protection interlock loops.

Product Details

Rack‑mount multilayer PCB fits inside Mark V cabinet slot and requires matched I/O control board for operation. Conformal coated circuit board resists dust, moisture and heavy electromagnetic interference for long‑term power‑plant operation. This part is end‑of‑life from original manufacturer, widely used for unit maintenance and spare‑part replacement. Please verify hardware revision before installation for full system compatibility.
