The YCV8-02 AD240V modular relay from CNC Electric is a compact and reliable voltage monitoring device designed for AC240V single-phase systems. It uses True RMS measurement to ensure accurate voltage detection even under waveform distortion. The relay supports adjustable delay (0.1s–10s) and a reset time of 1000ms, allowing flexible control logic.
It includes a 1×SPDT output rated at 10A/AC1, suitable for switching 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 residential, industrial, and mobile equipment applications, including emergency switching and phase failure protection.
