New-Surplus DS200SDCIG1AEB, Open Box

This listing is a new-surplus, open-box DS200SDCIG1AEB – a G1-group SDCI, the DC Power Supply and Instrumentation board GE builds for its DC2000 static drive line. It's cataloged in the Mark V DS200 series because DC2000 drives like this one are commonly used as auxiliary or starting equipment on turbines controlled by a Speedtronic Mark V panel. Onboard you'll find several power supplies, motor field power circuits, driver circuits for armature SCR gating, and instrumentation circuits covering AC line and DC motor signals: armature current and voltage, field current and voltage, voltage magnitude, and phase sequence.

As a G1-group board, this unit includes an internal field exciter circuit rated at 10 amps or less – a functional distinction from G2-group SDCI boards, which are built for an external exciter instead. The SDCI, regardless of group, interfaces directly with drive-side field wiring, CTs, and shunts rather than the Mark V's <R>/<S>/<T>/<C> control cores.

About the Open-Box Condition

Open-box, in our listings, means new-surplus factory stock that has been removed from its original retail packaging – typically during inspection or inventory handling – but never installed or field-used. It carries the same 1-year warranty as our other new-surplus boards. Ask for label photos when requesting your quote if cosmetic condition matters for your records.

Know How to Diagnose This Board Before You Need It

Whether this unit goes straight onto a spares shelf or into service, it's worth understanding how to troubleshoot an SDCI properly rather than reaching for a spare at the first blown fuse. Every protective fuse – FU1 (115 VAC supply), FU2/FU3 (signal-level power), FU5/FU6 (internal NRX/MOV assembly) – has a dedicated LED that lights when it blows. When that happens:

• Fully de-energize the drive and let the board discharge before handling it – dangerous voltage can persist after shutdown.
• Check the field wiring on that circuit for a short or insulation fault before replacing the fuse. A fuse that blows once can be incidental; one that keeps blowing is telling you about a wiring or field-device problem, not a bad board.
• Fix the wiring fault first, then replace the fuse or board.

When you do install a replacement, match the outgoing card's jumper and switch settings – JP1 (MD control source jumper), JP2 (AC contactor drop-out time jumper), SW1 (AC line CT burden selection based on nominal DC output current) – and confirm your drive's exciter wiring before assuming a G1 board is correct.

Reading DS200SDCIG1AEB

DS200 is the board series prefix, SDCI is the DC Power Supply and Instrumentation acronym, G1 is the product group (internal field exciter, ≤10 A), and EB is the specific revision combination of this unit. GE's manual for this board family is referenced as GEI-100173. G1 and G2 reflect different exciter configurations, not simple revision levels, so match the group to your drive.

Related Boards and Broader Context

Because the SDCI sits on the drive/exciter side of the system, it isn't part of the Mark V turbine control core's card-to-card troubleshooting group (TCDA, TCEA, and similar). For how the SDCI's DS200 numbering fits within the wider Mark V board family, see our GE Mark V DS200 Boards Explained guide and the GE Speedtronic Part Number Decoder. For a longer-term platform view, see our Mark V vs Mark VI: DS200 to IS200 guide.
