Key Features

1. Power Distribution System Interface
   • Acts as a dedicated bridge between JPDB/JPDF/JPDE power boards and the Mark VIe controller.
   • Conditions and processes low-level feedback signals into Ethernet-compatible data for real-time monitoring.
2. Comprehensive Signal Monitoring
   • Captures 115/230 VAC analog feedbacks, ground fault signals, and fused AC circuit status.
   • Enables precise tracking of power distribution health, including voltage, current, and fault conditions.
3. Robust Self-Diagnostics & Fault Detection
   • Performs five automated self-diagnostic tests to validate hardware and communication integrity.
   • Integrates with JPDE boards for ground fault detection, ensuring early warning of electrical faults.
   • On-board LED indicators display real-time status (power, communication, faults).
4. High-Speed Ethernet Communication
   • Utilizes 100 Mbps IONet Ethernet for seamless data exchange with the Mark VIe controller.
   • Supports remote monitoring and control, allowing operators to address issues without physical access.
5. Compact & Rugged Industrial Design
