Ground Fault Board

The ISE Ground Fault Monitoring Board provides continuous monitoring of electrical isolation for subsea and robotic systems, supporting up to eight channels simultaneously. Designed to enhance system safety and reliability, the board detects insulation degradation and provides early warning of potential ground faults.

The system measures channel isolation relative to chassis ground for circuits below 30 VDC and generates an alarm when isolation falls below the configurable 500 kΩ trigger level. Isolation impedance values from 0 MΩ to 10 MΩ are reported at a default rate of 1 Hz through CAN bus or an isolated RS232 communication interface.

Compact and adaptable, the ISE Ground Fault Monitoring Board is designed for integration into complex vehicle and control architectures where reliable electrical system monitoring is critical.
