TECHNICAL SPECIFICATIONS FOR GE - IS200JPDLG1A

IS200JPDLG1A is a Local Pack DC Power Distribution Board manufactured and designed by General Electric as part of the Mark VIe Series used in the GE Distributed Control System. The Local Pack dc Power Distribution (JPDL) board enables daisy-chain connections for numerous downstream JPDL boards as well as dc power distribution between the source of control power (potentially JPDP or JPDS) and numerous I/O packs. Each I/O pack connection has branch circuit protection supplied by positive temperature coefficient fuse devices. In addition to controlling hardware redundancy, the board is made to make it simple to maintain up to three independent control power distribution circuits. It is typical to have separate control power for R, S, and T hardware in a TMR system. JPDL enables structured separation of the control power by including three independent power circuits on a single board.

INSTALLATION:

A metal bracket next to the I/O packets is where JDPL is mounted vertically. The cords for the power source enter from the back, while the cables for the output emerge out the front. The connectors are all Mate-N-Lok. Consult the circuit diagram for cable destinations.

OPERATION:

INPUTS:

Typically, up to three redundant feeds from JPDP or JPDS provide 28 V dc in input power. The three distinct power feeds are received by the 5-pin Mate-N-Lok input connector on three different pins for triple redundancy. The feeds are categorized as Red, Blue, and Black. This connection is made possible by the JP1, JP2, and JP3 connectors on JPDP. The remaining two pins of the 5-pin Mate-N-Lok connector are used to transmit the return current, which is shared by the three TMR feeds.

OUTPUTS:

Individual I/O packs are powered by six identical output circuits. Each of the R, S, and T feeds provides two (red, blue, and black). A resetting positive temperature coefficient fuse device with the designation CL (current limit) is included in each of the six I/O pack feeds to offer branch circuit protection that is coordinated with the wire between JPDL and the I/O pack.
