Product Overview

IS400TCASH1ADC is field‑wiring terminal board for legacy GE Mark IV / Mark V turbine‑control systems. It accepts multi‑type thermocouple inputs, performs cold‑junction compensation and noise filtering before feeding conditioned temperature signals to main control boards. This end‑of‑production turbine‑spare hardware is available as rebuilt and new‑old‑stock units for existing gas‑turbine power‑station maintenance.

Application Notes

‑ Mount inside GE Speedtronic turbine‑control rack. ‑ Match thermocouple type in system configuration software. ‑ Mandatory ESD protection before PCB handling. ‑ Typical deployment: legacy gas‑turbine power‑station temperature‑acquisition spare‑part stocking.
