4-gang Wi-Fi Smart Switch with RF Control 40A | Sonoff 4CHPROR3

The SONOFF 4CHPROR3 is a 4-channel Wi-Fi smart switch for DIN-rail mounting that controls four separate circuits from the eWeLink app, by voice, or with a 433 MHz RF remote. Each channel handles up to 10A, with a total of 40A for the whole unit, and it runs on 100–240V AC or 9–23V DC.

Four independent channels: Each of the four relays can be switched on and off on its own, so one unit can control four lights or appliances. Each channel is rated up to 10A, and the total load of all four channels together must stay within 40A.

Three working modes: In self-locking mode each channel is a normal on/off switch. In interlock mode only one channel can be on at a time, which is used for things like motors or curtains that must not run in two directions together. In inching mode a channel switches off automatically after a set time, like a push-button.

App, voice and RF control: Control the channels from the eWeLink app over 2.4 GHz Wi-Fi, by voice with Amazon Alexa or Google Home, or locally with a 433 MHz RF remote.

DIN rail mounting: The switch is designed to be installed on a DIN rail, for example inside an electrical panel.
