FUNCTIONAL DESCRIPTION:
IS210JPDDG2A is a DC Power Distribution Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Gas Turbine Control Systems. The DC Power Distribution (JPDD) board provides dc power distribution, power isolation, and branch circuit protection for control or I/O functions requiring 125 V dc, 48 V dc, or 24 V dc power. Typical applications include dc relay and solenoid control power, and contact wetting. Each output includes a fuse, a switch, and a lamp to indicate the presence of output voltage. JPDD is not intended for power distribution to the I/O packs. JPDDG1 provides fuses that are coordinated with the rating of the system wiring and connectors. JPDDG2 and G3 are used when fuse ratings coordinated with a specific application are required. Two different fuse sizes are provided to accommodate local fuse preferences.
INSTALLATION:
JPDD is held in a plastic holder, which mounts on a vertical DIN rail. When installing the JPDD, it is important to provide a ground lead from TB1 to the system ground. This creates a ground path for the metal switch bodies. Power input can be 24 V dc, 48 V dc, or 125 V dc, but only one voltage level at any given time. Do not mix voltages. For cable destinations, refer to the circuit diagram. TB1 should be connected to the system ground.
OPERATION:
The following figure shows how the 125 V dc, 48 V dc, or 24 V dc power is distributed in JPDD, and how it reaches the TRLY and TBCI boards. Multiple JPDD boards can receive power from a single Main Power Distribution Module branch circuit. Power input can be either 125 V dc, 48 V dc, or 24 V dc nominal. Two 2-Pin Mate-N-Lok connectors are provided for 125 V dc power. One connector receives input power and the other can be used to distribute 125 V dc power to another JPDD board in daisy chain fashion. Two 4-pin Mate-N-Lok connectors are provided for 24/48 V dc power. These perform functions similar to those of the 2-pin connectors above. The 4-pin connector permits parallel connection of two pin-pairs for increased current capacity. It is expected that neither side of the DC power input is grounded.
CONFIGURATION:
There are no jumpers on JPDD. Check the position of the six output load switches. It is possible to use other fuse ratings with this board to provide specific branch circuit ratings. A typical series of fuses that work with this board is the Bussmann ABC series of fuses with ratings from 1⁄4 A through 15 A. Fuses above 15 A shall not be used with this board. If alternate fuse ratings are used, the configuration of the board requires the insertion of the proper fuse in each branch circuit.

What is a DC Power Distribution Board?
A DC Power Distribution Board is an electrical component used to distribute direct current (DC) power from a single source to multiple devices or circuits. It typically consists of input terminals for the power source and output terminals for connecting the devices or circuits.
What are the common applications of DC Power Distribution Boards?
DC Power Distribution Boards are commonly used in various applications, including automotive, marine, telecommunications, renewable energy systems, and industrial machinery, where multiple devices need to be powered from a single DC power source.
What are the main components of a DC Power Distribution Board?
The main components of a DC Power Distribution Board include input terminals, output terminals, bus bars or distribution blocks, fuses or circuit breakers for overcurrent protection, and sometimes indicators for monitoring the status of individual circuits.
