Description
Product Introduction
GE IS200JPDGH1A is the JPDG high-density power distribution board in GE’s Mark VI and Mark VIe turbine control systems, serving as the central hub in the Power Distribution Module (PDM) chassis for dual-path DC power delivery to controllers, I/O packs, and terminal racks.xm-dcs+1
This card accepts redundant 28 V DC control power and 24/48 V DC wetting power, distributes them via fused and self-resetting outputs, and provides 115/230 V AC monitoring for diagnostic reporting in gas and steam turbine applications.xm-dcs+1
Frequently Asked Questions
Q: Can I hot-swap the IS200JPDGH1A?
A: No. The JPDG is a passive distribution card in the PDM chassis; it is not designed for hot-swap insertion. You must de-energize the PDM rack or isolate the affected power section before removal to avoid tripping the entire control system and to protect personnel from high-current DC bus connections.xyddcs+1
Q: Is the IS200JPDGH1A obsolete? Are there direct replacements?
A: Yes, the JPDG board is effectively obsolete in new GE production. Direct replacements are other JPDG variants (e.g., IS200JPDGH1ABD) or upgraded PDM boards in the same Mark VI/VIe family, but verify mechanical envelope, connector pinout, and current rating before swapping.dcsplcsystem+1
Q: Will I lose my turbine control program when replacing this board?
A: No. The IS200JPDGH1A is a passive power distribution module; it does not store control logic or parameters. Turbine control programs reside in the primary and secondary controllers (e.g., VCMI, VCMIH). However, always back up the Mark VIe project before any hardware intervention.axcontrol+1
Q: Are these units factory-new or refurbished?
A: Most available stock is New Surplus (original GE packaging, never installed) or tested used units with 12–36 month warranty. Genuine GE factory-new IS200JPDGH1A boards are rare. Request photos of packaging, revision labels, and serial numbers for audit.dcsplcsystem+1
Q: What warranty and lead time should I expect?
A: Surplus suppliers typically offer 12–36 months warranty on tested units; New Surplus may have 12–24 months. Lead times: in-stock units ship in 1–3 days, but export paperwork and customs can add 5–8 working days.
