The Arc Fault Detection Sensor is primarily used for real-time detection of arc faults in DC circuits. Upon detecting a fault arc, it immediately issues an alarm signal to notify the inverter or other actuators to disconnect the faulty circuit, effectively preventing fire hazards. Each module can support up to 4 channels simultaneously and allows for integrated current measurement. It supports module cascading, with a maximum of 8 cascaded modules, totaling 32 channels.
