IS400JPDHG1A FUNCTIONAL DESCRIPTION

IS400JPDHG1A is a High-Density Power Distribution Board manufactured and designed by General Electric as part of the Mark VIe series used in distributed control management systems. The High-Density Power Distribution (JPDH) board provides 28 V dc power to 24 Mark VIe I/O packs and 3 Ethernet switches from a 28 V dc supply. Additional JPDHs can be connected in a daisy-chain arrangement to provide power to more I/O packs as required. The circuit for each I/O pack connector is protected with a positive temperature coefficient fuse device.

The JPDH is a 28 V dc power distribution board. This board receives 28 V dc power from the R, S, and T power sources. It provides up to 24 output connectors at 28 V dc for I/O packs, eight each for R, S, and T. These outputs are protected with a positive temperature coefficient fuse.

The JPDH board also provides three unprotected 28 V dc outputs to be connected to R, S, and T Ethernet switches. The JPDH may also be used in daisy-chain mode to distribute 28 V dc power to more than 24 I/O packs.

IS400JPDHG1A OPERATIONS

The JPDH is designed to provide TMR I/O packs with adequate 28 V dc power distribution while taking up as little space as possible. Additional JPDHs can be connected in a daisy-chain arrangement through the unfused J1X connector. The 6-pin J1 connector brings in three separate 28 V dc feeds on three different pins for triple redundancy.

The return current is common among the TMR and daisy-chain feeds and is brought in on the remaining three pins. JPDH has 24 identical output circuits to provide power to the individual I/O packs. The R, S, and T feed each provide power to eight circuits. Each I/O pack circuit includes a positive temperature coefficient fuse device for branch circuit protection. The board also has three identical unfused output circuits to provide power to each Ethernet switch.
