FUNCTIONAL DESCRIPTION:

IS210JPDDG2A is a DC Power Distribution Assembly DIN Rail Module manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Gas Turbine Control Systems. The JPDD board provides DC power distribution, isolation, and branch circuit protection for control or I/O functions requiring 125 V DC or 24 V DC, commonly used for DC relay and solenoid control as well as contact wetting. Each output includes a fuse, a switch, and an indicator lamp to show the presence of output voltage, though JPDD is not intended to power I/O packs. JPDAG1 offers fuses matched to system wiring and connector ratings, while JPDAG2 and JPDAG3 are used for application-specific fuse requirements, with two fuse sizes provided to accommodate local preferences.

INSTALLATION:

The JPDD board is secured in a plastic holder that mounts onto a vertical DIN rail for easy and stable installation. When installing the JPDD, it is essential to connect a ground lead from TB1 to the system ground, which establishes a safe ground path for the metal switch bodies and ensures proper system safety. The board accepts either 24 V DC or 125 V DC as a power input, but both voltages must never be applied simultaneously. For accurate wiring to cable destinations, installers should refer to the corresponding circuit diagram. Proper connection of TB1 to the system ground is critical for maintaining system integrity and reliable operation of the board.

OPERATIONS:

Multiple JPDD boards can be powered from a single branch circuit of the Main Power Distribution Module, with nominal input voltages of either 125 V DC or 24 V DC. For 125 V DC power, two 2-pin Mate-N-Lok connectors are provided one for receiving input power and the other for daisy-chaining power to additional JPDD boards. Similarly, two 4-pin Mate-N-Lok connectors handle 24 V DC power, offering the same input and distribution functionality, with the added capability of paralleling the two pin pairs to increase current capacity. Neither side of the DC power input is expected to be grounded, ensuring proper system isolation and safe operation when multiple boards are connected in parallel or series configurations.

The JPDD board includes six identical output circuits, each designed to provide reliable control and protection for connected devices. Every output circuit features two fuses, a switch with a pair of isolation contacts on each side of the output, and a green indicator lamp that signals the presence of voltage across the output terminals. By including both a fuse and a switch contact on each side of the DC path, the board can operate with floating power sources, offering flexibility and enhanced safety in various system configurations while ensuring each output is properly protected and monitored.

CONFIGURATION:

The JPDD board does not use any jumpers, so it is important to verify the position of all six output load switches before operation. While the board comes with standard fuse ratings, it is possible to use alternate fuses to meet specific branch circuit requirements, provided they are compatible with the board�s design. A commonly used option is the Bussmann ABC series of fuses, available in ratings from 1 A to 15 A. Fuses exceeding 15 A must not be used, as they could compromise the board�s safety and performance. When installing alternate fuse ratings, it is essential to ensure that the correct fuse is inserted in each branch circuit to maintain proper protection and reliable operation of all outputs.

FREQUENTLY ASKED QUESTIONS

What is a DC Power Distribution Assembly DIN Rail Module?

It is a compact module designed to distribute DC power to multiple control or I/O circuits. It provides branch circuit protection, electrical isolation, and voltage indication for each output. The module can be easily mounted on a standard DIN rail for industrial and automation systems.

What voltages does the module support?

The module supports nominal input voltages of 24 V DC or 125 V DC. Both voltages must never be applied at the same time to ensure safe operation and prevent damage.

How many output circuits does it have?

The module typically includes six identical output circuits. Each output has a fuse, a switch with isolation contacts on both sides, and a green indicator lamp. This design allows safe operation with floating power sources.

Can multiple modules be powered from a single source?

Yes. Multiple modules can share a single branch circuit from the main power distribution module. The 125 V DC and 24 V DC connectors allow daisy-chaining or parallel connections for increased current capacity, enabling flexible system expansion.
