GE IS200JPDDG1AAA Power Distribution Board

GE IS200JPDDG1AAA Power Distribution Board

Configured for controlled DC branch routing in Mark VI power modules, the GE IS200JPDDG1AAA (IS200JPDDG1AAA DC PDM module) provides isolated branch‑circuit distribution, fuse‑protected outputs, and manual switching for relay, solenoid, and contact‑wetting loads. The board executes non‑jumpered configuration, localized overcurrent protection, and lamp‑indicated output status across six independent DC circuits.

Hardware Specifications

Backplane Bus Communication Velocity Licenses

As a Mark VI power‑distribution module, JPDD aligns with deterministic cabinet‑level routing and controller timing constraints:

• Profinet deterministic networks — stable cycle timing when upstream controllers enforce scheduled exchanges.
• EtherNet/IP deterministic behavior — predictable negotiation windows for CIP‑based traffic.
• I/O density scaling — consistent propagation delay across expanded turbine‑control node counts.
• Firmware flash compatibility — supervisory processor behavior remains fixed; no board‑specific firmware logic is user‑configurable.

Frequently Asked Questions (FAQ)

Q: Can JPDD be used to power I/O packs? A: No. JPDD supplies branch‑level DC power for relays, solenoids, and wetting circuits, not for I/O pack primary power.

Q: How many output circuits are available? A: Six isolated circuits, each with its own fuse, manual switch, and status lamp.

Q: Can alternate fuse ratings be used? A: Yes. Bussmann ABC fuses from 0.25 A to 15 A are supported. Ratings above 15 A must not be used.

Field Installation Guidelines

• Verify each of the six load switches is set according to the required branch‑power configuration.
• Maintain correct polarity and shielding on DC wiring to minimize noise coupling into relay and solenoid circuits.
• Insert only supported Bussmann ABC fuses; never exceed 15 A.
• Inspect status lamps after energizing to confirm branch voltage presence.
• Keep wiring separated from high‑current conductors to reduce induced transients.
• Ensure mechanical retention of connectors to avoid intermittent branch‑power delivery.
