Voltage-Free WiFi Relay - Impulse Control, eWeLink Compatible
A WiFi relay, compatible with the Sonoff eWeLink app, that allows for remote control of electrical devices such as furnaces, gates, actuators, or lighting. Thanks to its voltage-free control function, the relay only closes or opens a circuit (acting like a switch) without supplying voltage to its output. This allows for safe control of devices operating over a wide voltage range (0-240V). The module can operate in normally open (NO) or normally closed (NC) mode, which increases its versatility.
Key Features:
- Full compatibility with the Sonoff eWeLink app
- Voltage-free control – NO (normally open) and NC (normally closed) contacts
- Versatile power supply: 7-32V DC or via Micro USB 5V port
- Impulse (Inching) control function – ideal for gate control
- Advanced app functions: timers, schedules, scenes
- Maximum contact load up to 10A
- WiFi 2.4GHz wireless communication
Impulse Control and Versatile Applications
The relay features an impulse control function that can be activated in the eWeLink app. When enabled, the relay will automatically turn off after a set time (e.g., 1 second). This is an ideal solution for controlling entrance gates, actuators, or other devices that require a short pulse. The module is perfect for heating systems, home automation, and anywhere remote circuit switching is needed.
Relay Pinout Description
The module is equipped with ARK screw terminals, which makes it easy to connect power wires and the controlled device.
