IS400JPDHG1A - HD 28V DISTRIB switchboard

Part Number IS400JPDHG1A Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockIS400JPDHG1A 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. 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.Module manufactured by General Electric as part of the Mark VI/VIe Series used in gas turbine sppedtronic control systems
