IS210JPDDG3A 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 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.
Operation
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 a 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.
