Description
The SONOFF 4CHPROR3 is a 4-gang Wi-Fi smart switch with 433 MHz RF control, designed for DIN rail installation. It switches four independent channels at up to 10A / 2200W each (40A / 8800W in total), so you can control lights, pumps, motors, water heaters and HVAC equipment from the eWeLink app, by voice or with an RF remote.
It connects directly to your 2.4 GHz Wi-Fi network with no hub required and accepts 100–240V AC or 9–23V DC input. Self-locking, interlock and inching modes plus dry contact operation make it a fit for garage doors, motorized curtains, gates and other automation projects inside electrical panels.
Note: requires a 2.4 GHz Wi-Fi network and the eWeLink app.
