FUNCTIONAL DESCRIPTION:

IS230JPDMG1A is a Power Distribution (JPDM) Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The Power Distribution (JPDM) board receives 28 V dc input power from external ac/dc or dc/dc converters and distributes power to the control system. JPDM provides fuse protection for all outputs. JPDM integrates into the PDM system feedback through the PPDA I/O pack. JDPM is designed to maintain three separate power buses for R, S, and T applications. Jumpers can be used to provide a single bus with redundant supplies. Two adjacent JPDM boards can be wired together.

COMPATIBILITY:

The IS200JPDM 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 JPDM is compatible with the IS220PPDA I/O pack.

INSTALLATION:

The JPDM is base-mounted vertically on a metal bracket in a cabinet used by the PDM. Refer to the wiring diagrams for power input and output. There is a 50-pin diagnostic connector, P1/P2, mounted on the top and bottom of the board.

OPERATION:

• JDPM supplies three power supply inputs on JR, JS, and JT. Each connector uses pins 8 and 9 for positive 28 V dc and pins 1-3 for 28 V dc return providing 24 A steady state capacity. These connectors include low-level signals capable of monitoring status switches on each supply and sending feedback signals to PPDA. Pin 4 provides +10 V dc wetting to the status switch and the return is on pin 5.

• Terminal boards TB1 and TB2 at the bottom and top of the board provide access to the three power buses. Jumpers can be used to parallel the bus between TB1 and TB2 when more than one JPDM board is used. Jumpers can also be used between terminals PR, PS, and PT to tie the positive bus terminals together when a single power bus is fed by redundant power supplies.

• Three fused two-pin Mate-N-Lok connectors, JCR, JCS, JCT power controllers, and other loads. Pin 1 is +28 V dc and pin 2 is the return. A 10 A fuse protects the circuit.

• A DC-62 connector, JA1, is for connecting to a PPDA I/O pack. The pack contains status feedback signals for up to six core power distribution boards.

• Two 50-pin diagnostic ribbon cable connectors, P1 and P2, are supplied on the top and bottom of the board. Connector P1 transmits feedback signals to a board hosting a PPDA I/O pack. Connector P2, when connected, receives feedback from another power distribution board and passes the signals out of P1 towards the PPDA.
