The YCV8-02 DC12V modular relay from CNC Electric is designed for precise voltage monitoring and protection in DC12V single-phase systems. It uses True RMS measurement to ensure accurate voltage detection, even under waveform distortion. The relay includes an adjustable time delay (0.1s–10s) and a reset time of 1000ms, allowing flexible control logic.
Equipped with a 1×SPDT output rated at 10A/AC1, it can switch loads up to 250VAC or 24VDC. LED indicators show green for power supply and red for output status. The device mounts on a 1-module DIN rail (EN/IEC 60715) and complies with EN60255-1 and IEC60947-5-1 standards.
With IP40 front protection and IP20 terminal protection, it’s ideal for mobile equipment, emergency power switching, and phase failure protection in residential, commercial, and industrial environments.
