A Label With More Than One Name

This unit's listing carries several identifiers at once: DS3815PDPA1G1A, DS3800HFPG1D1B, and the description "Display Driver." In GE's Speedtronic Mark IV lineup, "Drive Control Board" is the function most commonly associated with the DS3800HFPG part number, built around a microprocessor and EPROM modules that hold the firmware for the drive function it controls. GE's Mark IV family also includes boards documented elsewhere specifically as display driver cards, which are a different function entirely. Because this listing's naming isn't fully consistent, the safest path is to send us a photo of the actual label on your board before ordering — we'll confirm which function and revision you actually have and whether it matches what your panel needs.

What we can confirm about the DS3800HFPG hardware itself: it's a double-width card that seats in a dedicated two-slot rack position through modular connectors at the rear, held by retention levers, with a 34-pin connector and test points on the front and a 40-pin connector on the board surface feeding a ribbon cable to neighboring cards.

Before You Buy, Check These

• Confirm the function on the label, not just the listing title. With two part-number families and a function description in play, verify the exact markings on your existing board before assuming this is a straight match.
• Ribbon cable routing. If the cable from the 40-pin connector crosses the microprocessor, it can block cooling airflow and cause heat-related faults that clear once the board cools — easy to mistake for a failed processor.
• Full seating on both rear connectors. A double-width card resting on only one connector can misbehave in ways that mimic a bad board.
• EPROM modules. These typically move from your old board to the replacement, which ships with empty sockets; a loose module can look like total board failure.

Reading the Suffix

Where a DS3800HFPG part number applies, "1D1B" following the HFPG function code is GE's revision/variant marker. We stock this Drive Control Board across several such suffixes — 1B1B, 1D1B, 1D1C, 1D1D, and 1D1G — and treat each as a distinct revision that should be matched to your existing label rather than assumed interchangeable. Our GE Speedtronic Part Number Decoder explains the general structure of these GE part numbers.

Part of a Larger DS3800 Family

Whatever the exact function of this specific card, it belongs to the broader DS3800 series used throughout Mark IV panels — alongside processor boards like the DS3800HMPK, memory boards, and analog I/O cards. Browse the family in our GE Mark IV DS3800 Boards collection. If your plant runs Mark V (DS200-series) or Mark VI/VIe (IS200-series) instead, that's a different hardware generation — see our Mark V vs Mark VI: DS200 to IS200 guide.

Send Us the Label Photo

Because this listing spans more than one naming convention, please include a clear photo of your existing board's label with your quote request, along with the part number(s) you see printed (DS3815PDPA1G1A and/or DS3800HFPG1D1B), your turbine model, confirmation it's a Mark IV system, quantity, and urgency. This unit is used, cleaned and tested, with a 1-year warranty. We ship worldwide DDP (Delivered Duty Paid), accept purchase orders, and respond within 24 hours.
