IS200JPDGH1B GE Mark VI

The IS200JPDGH1B is a Jumper Power Distribution Card (JPDG) and a core component of the PDM (Power Distribution Module) subsystem. Installed within the power distribution module of the engine control cabinet, this card distributes externally supplied control power and wet-contact power to multiple I/O cards, terminal blocks, and processor modules inside the cabinet. It serves as the central hub for power transmission throughout the entire control system.

The IS200JPDGH1B features LED channel status indicators on the board, allowing field inspection personnel to intuitively determine the operational status of each output channel without measuring them individually with a multimeter. This board is part of the JPDG series and shares its core architecture with other models in the series, such as the IS200JPDGH1A and IS200JPDGH1ABD. The main differences lie in the hardware revision level and enhanced diagnostic capabilities.

• Product Type: Jumper Power Distribution Card (JPDG)
• Function Abbreviation: JPDG
• Maximum Current: 40 A
• Input Power: 28 VDC control power supply (dual-channel redundant)
• Dry Contact Power Supply: 24 / 48 VDC
• AC Monitoring: 2 channels (115 V / 230 V AC)
• Output Channels: Multiple independent fused outputs
• Operating Temperature: -30°C to +65°C (standard temperature version)
• PCB Coating: Conformal coating
• Mounting Method: Cabinet backplane / DIN rail

The IS200JPDGH1B must be used in conjunction with the following components in the system:

• IS200JPDMG1A: Main distribution panel with a 40 A busbar, providing a 28 VDC upstream input to the JPDGH1B.
• IS200JPDSG1A: Dual-redundant selection board, providing automatic upstream busbar switching for the JPDGH1B.
• IS200JPDFG1A: EMI filter board, which can be connected in series upstream of the JPDGH1B to reduce conducted interference.
• IS200JPDPG1A: 10 A branch board, used for secondary distribution downstream of the JPDGH1B.
• I/O Pack Series (e.g., IS220PAICH1B, IS220PDIAH1B, etc.): Obtains control power and wet contact power via the JPDGH1B.

A plant upgraded its existing Mark VI control system to the Mark VIe architecture. The newly installed IS200JPDGH1B power distribution panel supplies wet-contact power to seven I/O terminal boards. Due to the presence of mildly corrosive gases in the field environment, the conformal coating version was selected. An inspection conducted two years after operation revealed no signs of corrosion on the board surfaces, and the voltage deviation for all output channels remained within ±2%.

No, it does not. It is purely power distribution hardware and does not contain an onboard CPU. Fault signals are sent via a ribbon cable to the PPDA I/O pack for system-level processing.

The standard version operates from -30°C to +65°C, while the high-temperature variant extends the range to -40°C to +75°C.

Typically, the warranty period for original products is 12 months.
