FUNCTIONAL DESCRIPTION:

IS200JPDPG1AAA is a Local Power Distribution Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The JPDP board provides intermediate 28 V DC power distribution from the JPDM board to multiple JPDL boards for further distribution to the I/O packs. These JPDL boards are responsible for further distributing power to the I/O packs, which are essential components for processing and controlling field inputs and outputs in the system. This ensures that power is efficiently routed through the control system while maintaining system integrity and performance. Ethernet switches are used for communication between various system components, and providing power to them directly from the JPDP board ensures stable network communication within the control system.

INSTALLATION:

The JPDP (Junction Power Distribution Panel) is designed to be mounted in a plastic holder that fits securely on a vertical DIN rail. Ensure that the DIN rail is properly installed and fixed to the wall or rack, ensuring it is level and can support the weight of the JPDP and any other power distribution boards that may be mounted alongside it. The power input and output cables of the JPDP are equipped with Mate-N-Lock connectors. These connectors ensure secure, reliable, and easy connections. Connect the incoming power supply cable to the designated input terminal on the JPDP, ensuring that the polarity and voltage ratings match the specifications.

OPERATION:

The distribution of the 28 V DC power in JPDP and how it reaches the I/O packs and Ethernet switches are depicted in the accompanying diagram. The LPDB receives electrical power from the main power source, such as a utility supply, generator, or transformer. The incoming power is routed through the main circuit breaker, which controls the entire board. The incoming power is divided into smaller circuits using busbars. Each circuit is assigned to a specific area or device, ensuring organized power distribution.

INPUTS: Input power is typically 28 V dc, received from the JPDM (referred to as Pbus). The 6-pin Mate-N-Lock input connector receives three separate Pbus feeds from JPDS for triple redundancy. The feeds are designated Red, Blue, and Black.

OUTPUTS: Three identical output circuits provide power feeds to JPDL boards. Each JPDL output uses a 5-pin Mate-N-Lock connector. Three of the five pins are for Red, Blue, and Black. The other two pins are for Pbus return. Six identical outputs are provided for Ethernet switches. Two connectors are dedicated to each of the three feeds (red, blue, and black).

FREQUENTLY ASKED QUESTIONS:

What is the purpose of a Local Power Distribution Board?

The primary purpose of an LPDB is to distribute power from a central distribution unit to multiple components or systems, such as I/O packs, Ethernet switches, or other critical control elements. It ensures each part of the system receives the necessary power to function properly.

How does the LPDB connect to other system components?

The LPDB connects to the central power source through input connectors, and it provides power to downstream components through output connectors. These connectors are often designed for secure and reliable connections, such as Mate-N-Lock connectors, to ensure minimal risk of disconnections or faults.

What type of power does the Local Power Distribution Board supply?

The LPDB typically supplies DC or AC power, depending on the system’s requirements. The most common voltage for control systems is 28 V DC, but the exact voltage and type of power depend on the specific model and application.
