The YX1 series is a smart relay module developed by VIOX for home automation and industrial control applications. It operates on 2.4GHz WiFi, allowing both local WLAN and remote app control. Users can manage devices via Android or iOS apps, and it is compatible with major voice assistants for hands-free operation. The module supports a 10A rated current, works in temperatures from -10ºC to 60ºC, and offers both built-in and external antenna options for reliable wireless communication . Key features include:
In contrast, protective relays in power systems are devices that detect abnormal electrical conditions (like overcurrent, overvoltage, or short circuits) and trigger circuit breakers to isolate the faulty section, ensuring system safety and continuity . Protective relays can be:
While the YX1 relay provides intelligent switching and remote control for smart devices, it is not a traditional protective relay used for electrical fault protection. If your goal is relay protection in power systems, you would typically use relays designed to sense abnormal currents or voltages and operate circuit breakers to isolate faults. The YX1 relay, however, is ideal for automation, remote equipment management, and smart control systems .
