Sonoff 4CH PRO – the ideal solution for centralized control of a group of electrical appliances. It lets you combine four independent devices into one system and control them via smartphone, voice or a 433 MHz remote. The device is perfect for automating garage doors, irrigation, lighting in several rooms or curtain motors. Thanks to its three operating modes, the 4CH PRO easily adapts to specific tasks: from simple power supply to complex motor switching systems.
Why choose Sonoff 4CH PRO:
Independent control of 4 channels: Four relays in one housing – control lighting or appliances individually or in groups.
Three operating modes:
Self-locking: turn each channel on/off separately.
Inching: automatic shut-off after a set time (ideal for gates or irrigation systems).
Interlock: only one of the four channels can be on at a time (for example, for motor control).
Flexible control: Wi-Fi connection for the eWeLink app, 433 MHz (RF) remote control, voice assistants and physical buttons on the housing.
DIN rail mounting: The device is designed for professional installation in a distribution panel.
Reliability: High-quality components ensuring stable operation of all channels under load.
