Overview
Configured for 28 VDC power distribution in the Mark VIe control system, the GE IS200JPDMG1A (IS200JPDMG1A Power Distribution Board) provides direct electrical power routing and output circuit protection. The board receives input power from external AC/DC or DC/DC converters and distributes protected power to connected control boards, controller circuits, auxiliary devices, and the PPDA power diagnostic pack.

Power Distribution and Industrial Control Integration
The IS200JPDMG1A distributes the 28 VDC input across multiple protected output circuits. Each output group uses dedicated protection according to its connected load and circuit function.
J1 through J3 provide protected power connections for JPDP or JPDL boards. Meanwhile, JCR, JCS, and JCT supply controller power through individually fused circuits. The JAR, JAS, and JAT connections support auxiliary devices through filtered outputs and self-resetting fuse protection.
The board also supports the PPDA I/O pack through the P4 connection and provides a dedicated JA1 connection for the PPDA power diagnostic pack. This arrangement allows the Power Distribution Module system to monitor selected power distribution parameters through the associated diagnostic hardware.
Within GE industrial control architectures, hardware integration depends on controlled backplane and I/O system interfaces. Therefore, the IS200JPDMG1A should be installed with compatible Mark VIe power distribution hardware and associated converter circuits. Verify firmware and connected hardware compatibility at the system level before commissioning or replacing related control components.
Frequently Asked Questions
Q: What input power does the IS200JPDMG1A Power Distribution Board use?
A: The supplied specifications identify a 28 VDC input. External AC/DC or DC/DC converters provide this power to the board for distribution to connected circuits.
Q: How are the controller and board output circuits protected?
A: J1-J3 and JCR-JCT circuits use 10 A, 250 V fuse protection. JAR-JAT auxiliary circuits use 3.75 A self-resetting fuse protection.
Q: Can the IS200JPDMG1A supply power to PPDA diagnostic hardware?
A: Yes. The P4 connection supplies PPDA I/O pack power with a maximum current of 0.25 A, while JA1 supports the PPDA power diagnostic pack with up to +/- 5 V.
Field Installation Guidelines
- Disconnect and isolate the external power source before installing or removing the board.
- Mount the IS200JPDMG1A securely on the specified DIN rail and verify mechanical engagement.
- Confirm the external supply matches the specified 28 VDC input requirement before energizing the circuit.
- Route power wiring separately from high-noise switching, motor, and high-current conductors where practical.
- Inspect all J-series connections for correct circuit assignment before applying power.
- Verify fuse ratings and replacement types against the installed circuit requirements. Do not install a higher-rated fuse to bypass an overcurrent condition.
- Check the P4 and JA1 connections carefully when installing PPDA diagnostic hardware.
- Follow applicable hazardous-area installation practices for Class 1 Division 2 environments.
- Inspect terminal connections, wiring insulation, and grounding arrangements during commissioning and scheduled maintenance.
