Technical Parameters
Core Advantages
1. Critical Power Distribution for Turbine Control
The IS410JPDHG1A is the central power distribution hub within the Mark VIe control cabinet. It supplies wetting power to dry contact input circuits (YDIAS, PDIO modules), relay coils, solenoid valves, and terminal boards throughout the system. Without stable power distribution, the entire I/O network loses its wetting supply, causing loss of contact input detection and control output actuation.
2. Redundant Input Architecture
The module accepts dual 28 VDC inputs with reverse polarity protection. If one power source fails, the module continues operating from the remaining source without interruption. This redundancy is essential for maintaining turbine control availability during power supply maintenance or fault conditions.
3. Per-Channel Fault Isolation
The 24 output channels are individually protected by 0.8 A PolyFuse devices. If a field wiring short occurs on any single channel, only that channel is affected; the remaining channels continue supplying power to their respective loads. The self-resetting PolyFuse automatically restores power once the fault condition is removed, eliminating the need for manual fuse replacement.
4. Comprehensive System Diagnostics
The module integrates with the PPDA diagnostic module for real-time monitoring of input and output current and voltage conditions. This diagnostic capability enables operators to detect power supply degradation, ground faults, and fuse failures before they escalate into system-level issues.
5. Proven Reliability in Harsh Environments
With an operating temperature range of -40°C to +70°C and conformal coating protection, the IS410JPDHG1A is designed for deployment in demanding industrial environments. Hazardous location certifications (Class I, Div 2 / ATEX Zone 2) make it suitable for installation in classified areas.

Frequently Asked Questions (FAQ)
Q1: What is the GE IS410JPDHG1A?
It is a Power Distribution Module (PDM) for the GE Mark VIe/Mark VIeS turbine control system. It distributes 28 VDC wetting power to I/O packs, relay coils, solenoid valves, and control circuits while providing per-channel fault protection.
Q2: Does the IS410JPDHG1A support redundant power inputs?
Yes. The module accepts dual 28 VDC input sources with reverse polarity protection and supports continued operation when one power source is lost.
Q3: How many output channels does this module have?
It provides 24 fused output channels, grouped as JR1-8, JS1-8, and JT1-8 (3 groups × 8 channels).
Q4: What type of protection is used on the output channels?
Each output channel uses a 0.8 A PolyFuse for self-resetting short-circuit protection. If a fault occurs, only the affected channel is limited; power automatically restores when the fault is removed.
Q5: What diagnostic capabilities does the module provide?
The IS410JPDHG1A interfaces with the PPDA diagnostic module for monitoring input and output current and voltage conditions. LED indicators provide visual status for input, output, and fault conditions.
Q6: What is the input voltage range?
The module operates on a nominal 28 VDC supply with a wide input range of 18–32 VDC.
Q7: What is the operating temperature range?
The module operates from -40°C to +70°C (-40°F to +158°F) and can be stored from -40°C to +85°C.
Q8: Is this module certified for hazardous locations?
Yes. It carries Class I, Div 2 / Class I, Zone 2 / ATEX certifications for use in classified areas.
Q9: What is the country of origin?
United States (USA).
Q10: What should I verify before ordering?
Always verify the exact part number (IS410JPDHG1A vs. other JPD variants), confirm your system configuration (Mark VIe vs. VIeS), and check the existing module part number for compatibility.
