FUNCTIONAL DESCRIPTION:

IS200JPDLG1AAB is a Local Pack DC Power Distribution Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The Local Pack DC Power Distribution (JPDL) board provides DC power distribution between the source of control power (possibly JPDP or JPDS) and multiple I/O packs, as well as provides daisy chain-style connections for multiple downstream JPDL boards. Branch circuit protection is provided for each I/O pack connection with positive temperature coefficient fuse devices. The board is designed to make it easy to maintain up to three isolated control power distribution circuits to complement control hardware redundancy. In a TMR system, it will be common to have separate control power for R, S, and T hardware. By providing for three separate power circuits on one board, JPDL allows organized separation of the control power.

INSTALLATION:

The JPDL board is designed for vertical mounting on a metal bracket positioned adjacent to the I/O packs, ensuring compact and organized placement within the control system rack. DC power input cables are connected at the rear of the board, while output cables to the I/O packs and downstream JPDL boards are routed from the front, facilitating easy access for wiring, inspection, and maintenance. This configuration supports efficient power distribution and reduces cable congestion, while maintaining clear separation of control power circuits for redundancy and system reliability. Proper grounding and secure mounting are recommended to ensure optimal performance and minimize electrical noise or interference.
Mounting the Board: Secure the JPDL board vertically on a metal mounting bracket located adjacent to the I/O packs. Ensure the bracket is properly grounded to prevent electrical interference.

• Connecting Power Inputs: Route the DC power input cables from the power source (JPDP or JPDS) to the rear terminals of the JPDL board. Verify polarity and tighten all connections to manufacturer-specified torque values.

• Connecting Output Cables: Connect the output cables from the front terminals of the JPDL board to the I/O packs and any downstream JPDL boards. Maintain clear labeling for each circuit to support easy identification and maintenance.

• Verifying Circuit Protection: Ensure that all branch circuits are equipped with positive temperature coefficient (PTC) fuses. Check that fuse ratings align with connected I/O pack requirements to prevent overloads.

• Final Inspection & Testing: Confirm all connections are secure, mounting is stable, and cables are properly routed to avoid interference. Power up the system and verify correct voltage distribution across all circuits before putting the board into full operation.

OPERATION:

Input power is typically 28 V dc, received from JPDP or JPDS as up to three redundant feeds. The 5-pin Mate-N-Lok input connector receives the three separate power feeds on three different pins for triple redundancy. The feeds are designated Red, Blue, and Black. The JP1, 2, and 3 connectors on JPDP provide this connection. Return current is common among the three TMR feeds and is passed on the remaining two pins of the 5-pin Mate-N-Lok connector. Six identical output circuits provide power feeds to individual I/O packs. Two are sourced from each of the R, S, and T feeds (red, blue, and black). Each of the six I/O pack feeds includes a resetting positive temperature coefficient fuse device, labeled CL (current limit), to provide branch circuit protection that is coordinated with the wire between JPDL and the I/O pack.

FREQUENTLY ASKED QUESTIONS:

What type of connector is used for the input power connection?

A 5-pin Mate-N-Lok connector is used for the DC power input. Three pins are allocated for the R, S, and T feeds, while the remaining two are used for the common return current path.

How many isolated control power circuits are supported on the board?

The board supports three isolated control power circuits, one for each redundant feed (R, S, and T). This separation allows independent control power for each channel, enhancing fault isolation and system reliability.

How many output circuits are provided, and how are they distributed across R, S, and T feeds?

The JPDL board provides six identical output circuits, with two outputs sourced from each R, S, and T input feed. This allows balanced distribution of power across multiple I/O packs.
