Generic 8-80V Wi-Fi Single-Channel Relay Module

Description

The 8-80V Wi-Fi Relay Module is a compact, industrial-grade switching solution designed for integrating high-power electrical devices into smart home and automation systems. Its core is a reliable 5V single-channel relay capable of handling substantial AC and DC loads, protected by a flyback diode for inductive load safety. The integrated Wi-Fi connectivity, powered by a proven domestic module, enables seamless integration with common IoT platforms for remote management via smartphone from anywhere with internet access.

Engineered for flexibility, the board accepts a remarkably wide DC input voltage range, making it suitable for automotive (12V/24V), solar (48V), and standard DC power supply applications without concern for polarity. Onboard indicators for Wi-Fi status and relay operation provide clear visual feedback, while a physical mode selection jumper allows quick configuration between latching and momentary trigger behaviors without requiring firmware changes.
