GE IS400JPDHG1A – High-Density Power Distribution Board | Mark VI Turbine Control Platform
Engineering Background: The IS400JPDHG1A is a high-density power distribution board engineered by GE as a core infrastructure component within the Mark VI turbine control system. Designed to manage and distribute conditioned DC power across multiple I/O and processor modules, this board ensures stable, noise-isolated power delivery in demanding industrial environments including gas turbines, steam turbines, and combined-cycle power plants.
Product Positioning: As a critical backplane-level power component, the IS400JPDHG1A is specified by plant engineers and DCS integrators who require OEM-grade reliability for long-term operational continuity. Konmask.com supplies this module from verified inventory with full traceability documentation available upon request.

System Architecture & Signal Flow
Within the Mark VI architecture, the IS400JPDHG1A sits between the primary power supply module (e.g., IS420PSAH1A or equivalent) and the downstream I/O terminal boards (TBCI, TBAI, TBDO series). It receives regulated DC input and distributes it across multiple isolated rails to processor cards (VCMI, VCRC) and I/O boards, maintaining voltage stability under variable load conditions. The board’s high-density connector layout supports the Mark VI’s triple-redundant (TMR) and simplex (S) configurations.

Technical FAQ
Q: Is IS400JPDHG1A compatible with both TMR and simplex Mark VI configurations?
A: Yes. The board is designed for use across Mark VI simplex and TMR rack configurations. Verify your rack slot assignment with your GE system drawing before installation.
Q: Can this board be used as a direct replacement for a failed unit without reconfiguration?
A: In most cases, yes — the IS400JPDHG1A is a passive power distribution board with no firmware. Replacement requires only physical swap and connector re-seating. Always follow GE’s Mark VI maintenance procedures.
Q: Do you provide a warranty?
A: We offer a 90-day functional warranty on all modules. Extended warranty and exchange programs are available — contact us for details.
Q: Can you supply multiple units for a plant-wide spare parts program?
A: Yes. We support bulk procurement and consignment stocking programs. Contact our team for volume pricing.
