Product Overview

DS3800HMHA is analog signal‑interface circuit board for GE Mark IV turbine racks. It receives and conditions multiple field analog measurements from plant transmitters and sensors, converting them into logic‑level signals for the main microprocessor board. Designed for high‑EMI power‑station cabinet environments. Obsolete hardware available as refurbished and new‑old‑stock spare parts for legacy turbine‑system repair.

Application Notes

‑ Mount inside Mark IV turbine‑control rack. ‑ Match input signal range according to site transducer specifications. ‑ Apply ESD protection when handling bare PCB assembly. ‑ Typical deployment: thermal‑power‑plant gas‑turbine control‑cabinet spare‑part stocking.
