GE DS4815CHGA1A1A Mark IV Video Driver Card

General Electric DS4815CHGA1A1A is a video driver card from the Mark IV DS3800 board series, built as a variant of the DS3800HVDB printed circuit board. It drives the operator display output of the Mark IV turbine control, so a failure typically presents as a lost or corrupted operator screen while the turbine control itself keeps running -- an urgent problem for the operators, but not usually a trip. The card mates through two connectors: a five-pin right-angle male connector on one side and an AMP multi-pin connector on the other. Mark IV is the oldest of the GE Speedtronic generations still widely in service, and board availability is the usual constraint on keeping one running. Order this one by the full part number including the trailing revision letters, and check them against the board's own nameplate. GE turbine boards carry suffixes that are not cosmetic -- a board with a different revision can differ in firmware, connector or scaling and is not always a drop-in. GE does not publish a public datasheet for this board, so the order desk verifies the exact revision and system compatibility before quoting rather than matching on the base number alone. These are legacy turbine-control systems supported from surplus, refurbished and repaired stock; tell us whether a repaired exchange unit is acceptable, because it often shortens the lead time considerably.
