IS410JPDHG1A Mark VIe Power Distribution Module

The GE IS410JPDHG1A is a Power Distribution Module (PDM) designed for the Mark VIe and Mark VIeS Speedtronic turbine control systems. It serves as a critical power routing and protection component, distributing regulated wetting power to I/O packs, relay coils, solenoid valves, and control circuits throughout the control cabinet. As part of the Mark VIe's distributed architecture, the IS410JPDHG1A provides the electrical interface required for maintaining field-side circuit availability across control nodes. It accepts dual redundant 28 VDC inputs and distributes power through individually fused output channels, ensuring that a fault in any single field circuit does not propagate to the rest of the system. The module is configured specifically for wetting power distribution, supplying the necessary voltage to dry contact input circuits while integrating with the PPDA diagnostic module for real-time current and voltage monitoring.
