Functional Description

IS200JPDSG1ABB is a power distribution board developed by GE. It is a part of the Mark VIe control system. The 28 V Power Distribution (JPDS) board serves as a pivotal component in the power management infrastructure of the control system. It receives 28 V DC input power from external AC/DC or DC/DC converters and efficiently distributes power to various components of the control system, ensuring reliable operation.

Integration with Feedback Systems

  • Seamless Integration with PDM System: Integrates into the broader Power Distribution Module (PDM) system within the control framework. This integration involves the incorporation of the JPDS as a critical component responsible for efficient power distribution. By seamlessly integrating with the PDM system, the JPDS contributes to the overall functionality and reliability of the control system.
  • Utilization of Feedback from PPDA I/O Pack: The feedback provided through PPDA I/O pack is instrumental in system monitoring and control. The JPDS leverages this feedback to gather critical information about power distribution and performance. This feedback includes data related to voltage levels, current flows, and other key parameters essential for monitoring system health and diagnosing potential issues.
  • Enhanced Monitoring and Control Capabilities: Integration with the PPDA I/O pack enhances the monitoring and control capabilities of the JPDS and the broader control system. By utilizing feedback from the PPDA I/O pack, the JPDS can accurately assess the status of power distribution and identify any anomalies or irregularities. This proactive monitoring capability enables timely intervention and corrective actions to maintain system integrity and prevent potential failures.
  • Optimal Performance and Reliability: The seamless integration of the JPDS with feedback systems such as the PPDA I/O pack contributes to optimal system performance and reliability. By leveraging feedback data, the JPDS can effectively manage power distribution, identify potential issues early on, and ensure uninterrupted operation of critical components within the control system. This proactive approach to system monitoring and control enhances overall reliability and reduces the risk of downtime or disruptions.

Compatibility with Connector Systems

  • The board is designed to be compatible with the feedback signal P1/P2 connectors found on JPDB, JPDF, and JPDE boards, which lead to the PPDA I/O pack.
  • Additionally, the DC-62 connector on the JPDS board is compatible with the I/O pack, facilitating streamlined connectivity and interoperability within the system.


  • Mounting Options: Mounted using a metal holder designed to fit securely on a vertical DIN-rail. This standardized mounting configuration allows for easy integration alongside other power distribution boards within the control panel. Additionally, for enhanced installation flexibility, JPDS can be supplied with a metal holder specifically engineered for direct mounting. This option accommodates various installation configurations and requirements, providing versatility to suit different application scenarios.
  • Wiring Guidance: Detailed wiring diagrams are provided by the manufacturer to guide the routing of power input and output connections during installation. These diagrams offer clear instructions and visual representations, ensuring accurate and efficient installation. By following the provided wiring diagrams, installers can easily identify the appropriate connection points and routes, facilitating seamless integration into the control system setup.
  • Secure Mounting: Once the mounting location is determined and the JPDS is positioned accordingly, it is essential to ensure that the unit is securely fastened to prevent movement or displacement during operation. Proper mounting not only ensures stability but also helps maintain reliable electrical connections and system integrity over time.
  • Compliance with Safety Standards: During installation, installers should adhere to all relevant safety guidelines and regulations to ensure the safety and integrity of the installation process. This includes using appropriate tools and equipment, following manufacturer instructions, and complying with electrical codes and standards applicable to the installation location.
  • Testing and Verification: After installation is complete, it is recommended to perform testing and verification procedures to ensure proper functionality and performance  within the control system. Testing may involve verifying power distribution, checking for proper wiring connections, and conducting functionality tests to ensure operation.

Diagnostic Capabilities

  • It features a 50-pin diagnostic connector mounted on both the top and bottom of the board, facilitating diagnostic testing and troubleshooting procedures.
  • This dual connector configuration enhances accessibility and ease of use during diagnostic tasks, enabling swift identification and resolution of potential issues.

Grounding Arrangements

  • To ensure proper grounding and electrical safety, the board is grounded through the sheet metal bracket to the underlying back base. In most cases, the system Functional Earth (FE) serves as the grounding reference, ensuring compliance with safety standards and regulations.
  • The 28 V Power Distribution board plays a critical role in the efficient and reliable operation of the control system, offering seamless integration, compatibility with feedback systems, and straightforward installation procedures, backed by robust diagnostic capabilities and stringent grounding arrangements.


  • Six 6-Pin Connections for JPDP or JPDL Boards: Each of these six connections supports JPDP or JPDL boards, offering a maximum current of 13 A per pin. These connections are crucial for interfacing with peripheral boards and modules within the control system, facilitating seamless communication and operation.
  • Three 2-Pin Connections for CPCI Control Rack Power: These three 2-pin connections are dedicated to providing power to the CPCI control rack, with each connection offering a maximum current of 12.5 A per pin. This ensures reliable power delivery to the control rack, enabling optimal performance of control modules and components.
  • Three 2-Pin Connections for Auxiliary Devices: These connections are equipped with filtering and fusing mechanisms to ensure the stability and safety of connected auxiliary devices. Each connection features a 1.6 A positive temperature coefficient fuse, providing protection against overcurrent and ensuring uninterrupted operation of auxiliary equipment.
  • One 50-Pin Ribbon Cable for Diagnostic Data Transmission: A 50-pin ribbon cable is utilized to transmit diagnostic data to downstream boards, facilitating comprehensive monitoring and analysis of system performance. This connection enables real-time diagnostic feedback, aiding in the identification and resolution of potential issues.
  • One 5-Screw Terminal Block for Daisy Chaining Power Distribution Boards: The 5-screw terminal block allows for daisy chaining of power distribution boards, streamlining the power distribution process within the control system. Each screw terminal supports a maximum current of 35 A, ensuring robust and reliable power transfer between interconnected boards.
  • One 2-Pin Connection for 28 V DC Power to the PPDA Pack: This connection provides 28 V DC power to the Power Plant Distributed Amplifier (PPDA) pack, supporting a maximum current of 0.25 A. The PPDA pack plays a crucial role in amplifying and distributing power within the control system, enhancing operational efficiency and reliability.
  • One 62-Pin D-Shell Connection for PPDA Power Diagnostic Pack: 62-pin D-Shell connection is dedicated to the PPDA power diagnostic pack, facilitating power monitoring and diagnostics. This connection supports ±5 V power transmission, enabling comprehensive analysis of power-related parameters and ensuring optimal system performance.
