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

  • The board seamlessly integrates into the Power Distribution Module (PDM) system, utilizing feedback provided through the Power Plant Distributed Amplifier (PPDA) I/O pack. This integration enhances system monitoring and control capabilities, ensuring optimal performance and reliability.

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.


  • The board is designed for straightforward installation, typically mounted in a metal holder that fits securely on a vertical DIN-rail alongside other power distribution boards.
  • Optionally, JPDS can be supplied with a metal holder specifically engineered for direct mounting, offering additional installation flexibility. Detailed wiring diagrams are provided to guide the routing of power input and output connections, ensuring accurate and efficient installation.

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.
