Product Function Description

DS200TCEAG1BNE TCEA terminal board is dedicated thermocouple signal interface for Mark V turbine system. It receives millivolt signals from thermocouple sensors on cylinder, exhaust and bearing positions, performs cold‑junction compensation and noise filtering, then sends processed temperature data to main I/O control board. On‑board jumpers select thermocouple types for different site conditions. Channel isolation reduces measurement error caused by ground loop. BNE revision improves compensation circuit precision, delivers reliable data for unit temperature monitoring and overtemperature protection interlock.

Product Details

Rack‑mount multilayer PCB fits inside Mark V cabinet slot and works cooperatively with matched analog I/O control board. Conformal coated circuit board resists dust, moisture and heavy electromagnetic interference for continuous power‑plant operation. Original manufacturer end‑of‑life product, widely used for unit maintenance and spare‑part replacement. Verify hardware revision and jumper setting before installation for full system compatibility.
