GE IS200JPDMG1ACC S1AT005-01 Jumper Power Distribution Module (JPDM)
Protected 28V DC Power Distribution for Mark VIe Turbine Control System I/O Packs & Hazardous Area Applications
1. Core Product Overview
The GE IS200JPDMG1ACC S1AT005-01 is a Jumper Power Distribution Module (JPDM) specifically engineered for the Mark VIe Speedtronic turbine control system, a core component for reliable power distribution in gas/steam turbine and industrial automation environments. It converts and distributes 28V DC control power from a 125V DC battery system (or 120/240V AC with converter) to individual I/O packs, offering dedicated protected power channels to ensure stable operation of control circuits. The module integrates 24 varistors and 24 two - position plugs (3 rows × 8) for flexible circuit configuration, and provides short - circuit protection (≤20A) and individual fuse protection for each output to prevent cascading failures. It is compliant with Class I, Div 2 (Groups A - D) and ATEX hazardous area standards, making it suitable for oil & gas, petrochemical, and power generation applications with explosive atmosphere risks.

2. Power Distribution & Protection Features
The IS200JPDMG1ACC S1AT005-01 distributes 28V DC power to up to 24 I/O pack channels, with each channel featuring a two - position plug for easy circuit isolation during maintenance. It uses J1/J1X connectors for daisy - chaining multiple JPDM boards, while limiting input current to the first JPDH J1 plug's rating to ensure system safety. The module includes 24 varistors for surge protection against voltage spikes from grid fluctuations or lightning strikes, and individual fuses (replaceable) for overcurrent isolation to avoid single - channel faults affecting the entire system. It supports redundant power input from dual 125V DC battery systems, enhancing power supply resilience in critical turbine control applications. The 28V DC output is regulated to ±1% tolerance, ensuring stable power for sensitive Mark VIe I/O electronics and communication modules.
