GE DS3800DFXX1B1B Mark‑IV Turbine Control Interface Circuit Board

Product Description

DS3800DFXX1B1B is a dedicated printed‑circuit interface board belonging to GE Speedtronic Mark‑IV (DS3800) turbine control system. It realizes internal signal transmission and data 

interaction between multi‑modules inside the turbine control rack, completes signal conditioning and data communication for gas turbine and steam‑turbine protection, speed regulation and 

sequence‑control loops. Equipped with ribbon‑cable connectors and configurable jumper pins, it requires jumper‑setting consistency during spare‑part replacement. Widely used in thermal‑power 

plants, combined‑cycle power stations and heavy‑duty industrial turbine equipment, it is an essential maintenance spare part for aging Mark‑IV control racks.
