GE IS230JPDGH1B

Product Overview

The IS230JPDGH1B is a 28V DC power distribution module engineered by GE for the Mark VIe and Mark VIeS Speedtronic turbine control systems, designed to reliably distribute power to critical control components while ensuring system integrity and redundancy. It supports dual 28V DC power inputs for redundant operation, distributes power to multiple downstream loads, and integrates with the PPDAH1B power monitoring module for real-time voltage and current tracking. The module features a DIN rail mounting design for easy installation in standard control cabinets, includes overcurrent protection via individual fuses for each output channel, and offers front-panel LED indicators for power status and fault detection.

Function Features

  • Dual Power Inputs: Supports two 28 VDC power sources for redundant operation, ensuring continuous power even if one input fails.
  • 8 Independent Output Channels: Distributes 28 VDC power to up to 8 downstream components, each protected by a 5 A fuse to prevent overcurrent damage.
  • PPDAH1B Integration: Interfaces with the PPDAH1B power monitoring module for real-time tracking of voltage and current levels across all channels.
  • DIN Rail Mounting: EN 50022-compliant DIN rail design enables quick installation and easy integration into standard control cabinets.
  • Front-Panel Diagnostics: 11 LEDs provide real-time status of power inputs, output channels, and fault conditions for rapid troubleshooting.
  • Hot-Swappable Fuses: Individual fuses can be replaced without system shutdown, minimizing maintenance downtime.
  • Conformal-Coated PCB: Protects against moisture, dust, and chemical contaminants, ensuring reliable operation in harsh industrial environments.
  • Hazardous Location Compliance: Certified for NFPA Class I Division II and ATEX Zone 2, enabling use in explosive atmospheres.
  • Reverse Polarity Protection: Guards against incorrect wiring of power inputs to prevent module damage.
  • Overcurrent & Short-Circuit Protection: Individual fuses for each output channel isolate faults and protect sensitive control components.
  • Redundant Power Switchover: Automatically switches to the secondary power input if the primary source fails, maintaining uninterrupted system operation.
  • ToolboxST Integration: Works with ToolboxST software for remote monitoring of power status and fault alerts.

Application Scenarios
