Product Introduction
In a Mark VIe cabinet, losing a single distribution card can take out an entire I/O section. The is a JPDC-series power distribution card used in GE Speedtronic Mark VI / Mark VIe turbine control systems. It sits inside the Power Distribution Module and helps distribute 28V DC control power to downstream I/O packs, terminal boards, and control circuits, with system-level health feedback supported through the PPDA distribution feedback unit.
Why this matters: JPDC/JPDG/JPDH cards are often confused during procurement, but they are not interchangeable. The JPDC card is part of the PDM power distribution hierarchy and must match the cabinet’s existing PDM configuration. For plants still running legacy Mark VIe systems, having a verified spare means you can restore a failed distribution path during a planned window instead of hunting for a board after a field alarm. These boards are discontinued and increasingly hard to source in clean condition.

Note: Exact current rating, fuse configuration, connector pinout, and PPDA compatibility depend on the specific PDM build and cabinet wiring. Always verify against your existing card label and the GE Mark VIe hardware manual.
Key Selling Points & Differentiators
- Correct JPDC card, not JPDG or JPDH. IS200JPDCG1ABA is a JPDC distribution card. It is not IS200JPDGH1A (JPDG parent board) or IS200JPDHG1AAA (JPDH downstream card).
- Fits Mark VIe PDM architecture. Designed for GE Speedtronic Mark VI/Mark VIe turbine control cabinets, not generic DIN-rail power supplies.
- PPDA-supported monitoring. Compatible with PPDA distribution feedback units for ground fault detection, bus voltage monitoring, and branch circuit status feedback.
- New surplus availability. Discontinued GE board. We stock verified, unused units — not pulled cards with unknown service history.
- Not recommended for Mark V DS200-series cabinets, non-GE turbine controls, or random 28V DC distribution racks.
- 12-month warranty with pre-shipment visual inspection and connector verification.
Quality Transparency SOP
- Label & revision audit. Verify “IS200JPDCG1ABA” and “JPDC” on the board label. Confirm suffix “ABA” matches the existing card.
- Visual PCB inspection. Check for burnt traces, swollen capacitors, cracked solder joints, or corrosion around fuse holders and power connectors.
- Connector pin check. Verify all backplane and ribbon-cable connectors are straight and undamaged. Bent pins cause intermittent distribution faults.
- Fuse & continuity check. Test fuse continuity and output pin-to-trace continuity with a multimeter. Confirm no open circuits on distribution rails.
- ESD packaging. Sealed in anti-static bag, foam-padded box, shipped with a signed inspection report.
Technical Risk Avoidance
- ❗ Do not substitute JPDC with JPDG or JPDH. JPDG is the upper-level parent board; JPDH feeds individual I/O packs; JPDC is a separate PDM distribution card. Mixing them will not restore power and may damage connectors.
- ❗ Confirm PPDA compatibility. If your PDM uses IS220PPDAH1A / IS200PPDAH1A for distribution feedback, verify the replacement JPDC card supports the same monitoring interface.
- ❗ Check fuses before declaring the card failed. A blown fuse on a JPDC card can look like a board failure. Test continuity before swapping.
- ❗ Verify cabinet wiring before removal. Removing the wrong distribution card can de-energize live I/O channels. Document slot position and connected loads first.
- ❗ Match the full part number. IS200JPDCG1A, IS200JPDCG1ABA, and other suffix variants may differ in revision, connector population, or firmware feedback mapping. Replace like-for-like unless engineering approves otherwise.
Buyer’s FAQ
Q: Is the same as IS200JPDGH1A? A: No. IS200JPDGH1A is the JPDG parent distribution board. IS200JPDCG1ABA is a JPDC distribution card. They serve different roles inside the Mark VIe PDM and are not interchangeable.
Q: What system is this card used in? A: It is used in GE Speedtronic Mark VI / Mark VIe turbine control systems, typically inside a Power Distribution Module that distributes 28V DC control power.
Q: Is this new or refurbished? A: New original surplus — factory sealed, never installed. We do not sell pulled or refurbished boards as “new.”
Q: Can I use IS200JPDCG1A instead of IS200JPDCG1ABA? A: Not without verification. The “ABA” suffix may indicate a specific revision, connector set, or configuration. Always match the full part number on your existing card before ordering.
Q: What’s the lead time and warranty? A: In-stock units ship within 1–2 business days. 12-month warranty from ship date, covering manufacturing defects and DOA failures.
