IS230JPDSG1A is a 28 V Power Distribution Board Manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Turbine Control Systems. The 28 V Power Distribution (JPDS) board receives 28 V dc input power from external ac/dc or dc/dc converters and distributes power to the control system. JPDS integrates into the PDM system feedback offered through the PPDA I/O pack. The IS200JPDS board is compatible with the feedback signal P1/P2 connectors on JPDB, JPDF, and JPDE leading to a PPDA I/O pack. The DC-62 connector on JPDS is compatible with the IS220PPDA I/O pack.


JPDS mounts in a metal holder, which fits on a vertical DIN rail next to other power distribution boards. Optionally, JPDS is also available with a metal holder designed for direct mounting. Refer to the wiring diagrams for power input and output routing. There is a 50-pin diagnostic connector mounted on the top and bottom of the board.


The JPDS is the power distribution board that receives 28 V DC power from the selected supplies and distributes it to the JPDP boards (for power to the I/O packs) and to the control racks. The normal 28 V power input to JPDS is through JR, JS, and JT connectors.

Three 28 V power input connectors, JR, JS, JT. The connectors on the power supplies have two connections for positive and three connections for negative power. In addition, there are three power supply health inputs each with two dry contact inputs per power source, which become diagnostic signals.

  • Three DC outputs, JCR, JCS, and JCT, to control rack CPCI power supplies
  • Six outputs to JPDP cards through six-pin connectors J1, J2, J3, J4, J5, J6 (3x2 Mate-N-Lok). This is the same connector with the same pin assignments used on JPDP. It is possible to directly connect up to six JPDL boards to JPDS to supply the I/O packs.
  • Three outputs JAR, JAS, and JAT, to auxiliary power connectors, each with a positive temperature coefficient fuse for current limiting and containing a common-mode choke for noise suppression.
  • Access to the internal 28 V bus at the board top and bottom using individual screw terminals on TB1 and TB2. Screw terminals for R, S, and T are sized to handle a maximum of 35 A continuous current. These terminals can be used to jumper boards together The screw terminal for ground is sized for 75 A.
  • DC-62 connector for PPDA power diagnostic I/O pack. The PPDA monitors JPDS and up to five additional power distribution boards connected to JPDS with a 50-pin diagnostic ribbon cable.

What is a 28V Power Distribution Board (PDB)?

A 28V PDB is a device used to distribute power from a 28-volt power source to multiple electrical loads or devices. It typically consists of input terminals, output terminals, and various protection mechanisms to ensure safe and efficient power distribution.

What are the common applications of a 28V Power Distribution Board?

These boards are commonly used in aerospace, automotive, marine, and industrial applications where a 28-volt power source needs to be distributed to various subsystems, equipment, or components.

What types of protection features are typically found in a 28V PDB?

Protection features may include overcurrent protection, overvoltage protection, undervoltage protection, reverse polarity protection, and short circuit protection. These mechanisms help safeguard the connected devices and prevent damage in case of electrical faults or anomalies.
