The IS200JPDCG1A is a Power Distribution Module designed and manufactured by General Electric for the distributed Mark VIe control systems. The Power Distribution Module (JPDC) combines input and output functions from several previous designs to provide distribution of 125 V dc, 115/230 V ac, and 28 V dc to other boards within a turbine control system. The module supports distributing 125 V DC, 115/230 V AC, and 28 V DC power rails to downstream boards and I/O packs, maintaining proper isolation between power domains. It incorporates internal protection elements such as fusing, surge suppression, and isolation networks to safeguard connected equipment from electrical faults, transients, and overload conditions.
COMPATIBILITY:
JPDCG1A can host a Power Distribution System Feedback (PPDA) pack used in the Mark VIe Power Distribution System. JPDC can also receive diagnostic feedback signals from other distribution boards and route these signals to the PPDA I/O pack as well. The intent is that the PPDA I/O pack should be mounted on the JPDC module. Therefore, no provision is made to transmit diagnostic signals from JPDC to another distribution board.
INSTALLATION:
The JPDCG1A module is typically mounted vertically with the 115/230 V AC input connector (JAC) at the bottom. It is attached with four screws using the mounting holes located at the top and bottom of the module base. Location within the control cabinet is not critical; however, distribution boards are usually mounted low in the cabinet to facilitate grounding. Refer to the section, Grounding. The optional PPDA I/O pack is plugged into connector JA1. It is secured to the JPDC base using an angle bracket, held in place with nuts threaded onto studs that are permanently attached to the base for that purpose. Diagnostic feedback inputs from other distribution boards are routed to JPDC through a 50-pin ribbon cable attached to connector P2. Input power connections include:

What is GE IS200JPDCG1A?
It is a 28 V DC Power Distribution Board designed by General Electric for the Speedtronic Mark VI and Mark VIe control platforms to manage branch power routing.
Why does the board feature a 30-second warning label?
The label warns operators to wait 30 seconds after turning off power before re-energizing the module, ensuring internal capacitors drain completely to prevent processing errors or hardware stress.
How does the module physically mount inside a control panel?
The card relies on robust standoffs and dedicated screw tracks that attach directly to a rigid metal sub-panel, preventing physical deflection and board-level trace damage.
What connector styles are available on the board face?
The card incorporates screw terminal blocks for primary power links, stab-on male terminals for fast hookup, and dedicated multi-pin plug ports for internal core links.
What is the nominal voltage distributed by this card?
It is engineered primarily to split, filter, and distribute localized industrial 28 V DC control system excitation power across the cabinet.
