Functional Description
IS400JPDSG1AFD is a power distribution board developed by GE. It is a part of Mark VIe control system. The 28 V Power Distribution (JPDS) board receive 28 V DC input power supply from external sources such as AC/DC or DC/DC converters, effectively channeling this power to various components within the system. This integration into the broader Power Distribution Module (PDM) system is facilitated by the feedback mechanism provided through the PPDA I/O pack.
Compatibility
- The compatibility of the board is a critical aspect of its functionality within the broader control system environment. It seamlessly integrates with various components, ensuring smooth operation and effective power distribution.
- The board interfaces effortlessly with the feedback signal connectors, denoted as P1/P2, found on JPDB, JPDF, and JPDE modules. These connectors serve as conduits for transmitting crucial feedback signals within the system, facilitating communication between different components. The feedback signals relay important information about the status and performance of the system, enabling efficient monitoring and control. Ultimately, this integration ensures that the board can effectively manage power distribution based on real-time feedback, enhancing overall system reliability and performance.
- Additionally, the compatibility extends to the DC-62 connector located on the JPDS board. This connector is specifically designed to interface with the I/O pack, enabling seamless communication and interaction between the two components. The I/O pack plays a vital role in processing input and output signals within the control system, contributing to its overall functionality and versatility. By establishing compatibility with the DC-62 connector, the IS200JPDS board facilitates the integration of the IS220PPDA I/O pack, ensuring smooth operation and interoperability.
Installation
- Mounting Configuration: The board is ingeniously crafted to fit seamlessly within a metal holder, specifically engineered to align with a vertical DIN-rail. This design choice optimizes space utilization and facilitates organized placement alongside other power distribution boards, enhancing the overall layout efficiency of the control system environment. Additionally, for added convenience, there is an option for JPDS to be equipped with a metal holder tailored for direct mounting, streamlining the installation process even further.
- Wiring Guidance: To ensure accurate and efficient power input and output routing, detailed wiring diagrams are provided as part of the installation documentation by GE. These diagrams serve as invaluable guides, illustrating the precise connections required for optimal functionality. By referencing these diagrams, installers can confidently navigate the wiring process, minimizing errors and ensuring that the board is seamlessly integrated into the broader power distribution network.
- Diagnostic Connector: A pivotal feature of the board is the inclusion of a 50-pin diagnostic connector, strategically positioned on both the top and bottom surfaces of the board. This diagnostic connector serves as a crucial interface for diagnostic procedures, enabling comprehensive testing, troubleshooting, and maintenance tasks. By accessing this connector, technicians can efficiently diagnose issues, identify potential faults, and perform necessary repairs or adjustments, thereby maximizing system uptime and reliability.
Grounding
- Grounding Mechanism: The board is grounded through a robust sheet metal bracket, which serves as a conduit for grounding the board to the underlying back base. This grounding mechanism establishes a secure electrical connection between the board and the system's functional earth (FE), a fundamental reference point for electrical potential within the system. By grounding the board in this manner, potential differences in electrical potential are mitigated, minimizing the risk of electrical hazards such as short circuits or electrical shocks.
- Sheet Metal Bracket: The sheet metal bracket plays a pivotal role in the grounding process, serving as both a structural support for the board and a pathway for electrical grounding. Constructed from durable materials, the bracket provides a stable mounting platform for the IS200JPDS board while facilitating the efficient transmission of electrical current to the back base. This ensures that the grounding connection is robust and reliable, contributing to the overall safety and stability of the electrical system.
- System FE: In most cases, the underlying back base serves as the system's functional earth (FE). The FE is a designated reference point within the system's electrical infrastructure, typically connected to the earth ground for safety and stability. By grounding the IS200JPDS board to the system FE, any stray currents or electrical disturbances are effectively dissipated, ensuring that the board operates within safe electrical parameters. This grounding configuration aligns with standard electrical practices and ensures compliance with safety regulations and guidelines.

Frequently Asked Questions
What is IS400JPDSG1AFD?
It is a power distribution board developed by GE under the Mark VIe series.
What are the analog P28 voltage readings for R, S, and T bus?
The analog P28 voltage readings for R, S, and T bus provide real-time information about the voltage levels on each bus within the system. These readings are invaluable for monitoring the electrical integrity and performance of the system.
What is the purpose of the dry contact provisions on the power supply connectors (JR1, JS1, JT1)?
The dry contact provisions on the power supply connectors serve to indicate the status of each power supply. These dry contacts are conditioned by the JPDS board, and their signals are incorporated into the feedback signal set. This allows for seamless monitoring of power supply status within the system.
How does JPDS provide feedback signals for the power supply status?
JPDS conditions the signals from the dry contacts on the power supply connectors (JR1, JS1, JT1) and includes them in the feedback signal set. This feedback mechanism enables real-time monitoring of power supply status, facilitating prompt detection of any issues or failures.
What is the purpose of the Auxiliary Supply status feedback provided?
The Auxiliary Supply status feedback from downstream of the fuses offers three feedback signals to the PPDA. These signals provide crucial information about the status of the auxiliary power supply, allowing for effective monitoring and ensuring uninterrupted operation of auxiliary components within the system.
