Product Overview

DS3800HCVA1J1H is a plug‑in signal‑conditioning circuit board for legacy GE Speedtronic Mark IV turbine control racks. It amplifies and filters analog feedback and drive signals for servo‑valve and actuator control loops, forming a critical signal‑path between main processor hardware and turbine field devices. This obsolete OEM board is available as refurbished and new‑old‑stock spare parts for existing combined‑cycle power‑plant turbine‑control cabinet maintenance.

Application Notes

‑ Install in GE Mark IV turbine control rack slots. ‑ Strictly follow terminal wiring documentation for signal polarity. ‑ Mandatory ESD anti‑static handling before PCB insertion or removal. ‑ Typical deployment: gas‑turbine power station control‑rack spare‑part stocking.
