GE DS3800HUMB-U27 General-purpose memory board for the gas turbine control system

Product Description

GE DS3800HUMB-U27 is a universal memory board (EPROM memory board) for the Speedtronic Mark IV gas turbine control system and a classic turbine spare part of the DS3800 series. The board is equipped with multiple EPROM memory chips, configuration jumpers, reset dip switches and status indicator LEDs. It is divided into four functional quadrants: A/B/C/D. It is used to store unit control programs, tuning parameters and logic configuration data. It loads programs and saves parameters for the main controller of Mark IV system to ensure normal operation of gas turbine speed control, fuel regulation and protection interlock logic. It is discontinued by the OEM. It is supplied as used refurbished or surplus stock spare parts for gas turbine retrofitting and replacement in power plants.
