GE IS200JPDCG1A Power Distribution Board

The GE IS200JPDCG1A, also cataloged as the JPDC Power Distribution Module, is a critical component in the Mark VI / Mark VIe Speedtronic Control Systems, designed to manage and distribute multiple voltage domains across turbine control architectures.

Technical Specifications

Functional Description

The IS200JPDCG1A consolidates input and output functions from prior designs to distribute 125 VDC, 115/230 VAC, and 28 VDC rails to downstream boards and I/O packs. It ensures isolation between power domains and integrates protective elements such as fuses, surge suppression, and isolation networks to safeguard against electrical faults and overloads.

Compatibility

• Hosts PPDA Power Distribution System Feedback pack within Mark VIe systems.

• Receives diagnostic feedback signals from other distribution boards and routes them to the PPDA I/O pack.

• Designed for direct PPDA mounting; no provision for transmitting diagnostics to other distribution boards.

Installation Guidelines

• Mount vertically with the 115/230 VAC input connector (JAC) at the bottom.

• Secure with four screws via mounting holes at the top and bottom of the base.

• Typically installed low in the cabinet to facilitate grounding.

• Optional PPDA I/O pack connects to JA1 and is secured with an angle bracket and threaded studs.

• Diagnostic feedback routed via 50-pin ribbon cable (P2).

Frequently Asked Questions

• What is GE IS200JPDCG1A?  A 28 VDC Power Distribution Board for Mark VI/Mark VIe platforms, managing branch power routing.

• Why the 30-second warning label?  Ensures capacitors discharge fully before re-energization, preventing hardware stress.

• How does it mount inside a control panel?  Using standoffs and screw tracks on a rigid metal sub-panel.

• What connector styles are available?  Screw terminals, stab-on male terminals, and multi-pin plug ports.

• What voltage does it distribute?  Primarily 28 VDC, with additional routing for 125 VDC and 115/230 VAC.
