Overview
The General Electric IS2020JPDBG01, also cataloged as the IS2020JPDBG01 Power Distribution Board, distributes AC power through separate input circuits and fused branch outputs within a GE Mark VIe control system. The board provides circuit-status feedback and passive AC monitoring interfaces for power diagnostics. It also supports signal pass-through from other power distribution system cards.

AC Power Distribution and Diagnostic Interfaces
The IS2020JPDBG01 contains two line filters and a power distribution circuit board. Each AC distribution circuit has a stated rating of 20 A at either 115 VAC or 230 VAC.
Each circuit provides one fused output and three fused, switched branch-circuit outputs. The board also offers a connection for an optional JPDF 125 VDC distribution module.
For systems designed to operate from a single available AC source without generating power diagnostic alerts, the supplied functional description specifies parallel wiring of the AC inputs. Confirm the approved system configuration and wiring diagram before applying this arrangement.
The board provides status feedback for fused circuits and passive monitoring of both AC input magnitudes. Connector P1 interfaces with a compatible PPDA power diagnostic I/O pack, while connector P2 passes monitoring signals from other power distribution system cards.
Frequently Asked Questions
Q: What AC input ratings does the IS2020JPDBG01 support?
A: The supplied specifications identify two separate AC distribution circuits, each rated at 20 A for 115 VAC or 230 VAC. Verify the applicable system wiring diagram before connecting the supply.
Q: How does the board report power distribution faults or circuit status?
A: It provides status feedback for fused circuits and passive monitoring of AC input magnitudes. Connector P1 supports monitoring connections to a compatible PPDA I/O pack.
Q: Can the board supply 125 VDC to trip solenoids directly?
A: The supplied data lists a 125 VDC trip solenoid rating and a connection for an optional JPDF 125 VDC distribution module. Direct load compatibility and the required external distribution hardware must be confirmed from the manufacturer’s documentation.
Field Installation Guidelines
- Verify the complete part number and hardware revision against the applicable Mark VIe system drawings.
- Confirm the permitted AC input voltage and current ratings before connecting either distribution circuit.
- Follow the manufacturer’s wiring diagram when configuring parallel AC inputs. Do not assume that parallel connection is appropriate for every redundant supply arrangement.
- Verify branch-circuit fuse ratings and switching arrangements before connecting field loads.
- Route AC power wiring separately from low-level monitoring and diagnostic signal wiring to reduce electrical interference.
- Connect P1 and P2 only to their designated compatible interfaces. Confirm connector pin assignments from the applicable manual.
- Check protective grounding, enclosure bonding, and terminal security in accordance with the system installation requirements.
- Isolate all relevant power sources before installation or maintenance. Verify the absence of hazardous voltage before handling the board.
- Confirm the operating temperature limits and DIN rail mounting requirements against the manufacturer’s documentation, as the supplied specifications require verification.
