Description
The GE IS200JPDGH1A (and its revision variant IS200JPDGH1ABD) is a Power Distribution Board specifically designed for the Speedtronic Mark VIe control system. This board functions as the central node for distributing 24V DC and 125V DC power to various I/O packs, terminal boards, and processor cores. It is engineered with high-current busbars and integrated protection to ensure stable power delivery in high-density control cabinets.
- System Series: Speedtronic Mark VIe
- Input Voltage: 125V DC (Nominal) or 24V DC (Redundant)
- Output Distribution: Multiple power branches for I/O and Control Cores
- Circuit Protection: Onboard fuses with diagnostic status monitoring
- Connectivity: High-amperage terminal blocks and D-type connectors
- Redundancy: Supports dual-feed power input configurations for high availability
- Feedback: Provides logic-level feedback of fuse status to the system controller

Application Fields
This power distribution board is a critical infrastructure component for heavy industrial control, including:
- Gas and Steam Turbine Control: Powering the Mark VIe processor and I/O modules that manage fuel, speed, and safety loops.
- Power Generation Plants: Distributing DC power to critical protection relays and thermal monitoring boards.
- Combined Cycle Plants (HRSG): Providing stable power for distributed I/O racks in heat recovery steam generator control.
- Industrial Automation: Supporting large-scale GE DCS installations requiring redundant power architectures.
Product Instructions
- Preparation: Verify the input power source matches the board’s rating (125V DC or 24V DC). Ensure the cabinet main breaker is locked out.
- Mounting: Secure the board to the internal cabinet panel using the specified screws. Ensure the board is electrically grounded via the mounting points.
- Wiring: Connect the primary and secondary power feeds to the large gauge terminal blocks. Connect the output cables to the I/O terminal boards and processor packs using the designated headers.
- Fuse Check: Before powering up, verify that all onboard fuses are correctly seated and have the correct amperage rating for the connected loads.
- Status Monitoring: Once energized, check the onboard status LEDs. Verify through the GE ToolboxST software that the power distribution status is reported as “Normal.”
Q&A – Common Questions
Q1: What is the significance of the “ABD” suffix on the part number? A1: The suffix denotes the revision history. “A” is the base version, and “BD” indicates minor hardware improvements, component changes, or manufacturing updates. Revision “ABD” is typically backward compatible with any IS200JPDGH1A model.
Q2: How do I know if an onboard fuse has failed? A2: The board includes diagnostic circuits that monitor each fuse. A failed fuse will usually trigger a local LED indicator and generate a “Power Distribution Fault” alarm within the Mark VIe diagnostic HMI.
Q3: Can this board be used for AC power distribution? A3: No, the IS200JPDGH1A is strictly designed for DC power distribution within the GE control ecosystem. Attempting to use AC power will cause immediate hardware failure and safety hazards.
