SONOFF 4CHPROR3: Versatile Power and Professional Control in Automation

At the heart of professional automation projects, the SONOFF 4CHPROR3 is a top-of-the-line smart relay designed to manage four different devices in your home and workplace from a single central point. Presented with Reqasmart's vision, this device is more than just an on/off switch; it's a true engineering marvel with dry contact, RF support, and three different operating modes.

Three Smart Modes for Every Scenario

4CHPROR3 distinguishes itself from its competitors with its operating principles that can be adapted to your intended use:

  • Self-locking: Allows you to turn up and down up to 4 devices completely independently of each other.

  • Interlocking: When you open one channel, it automatically closes the other three channels. This is a vital safety measure, especially for motors that change direction (forward-reverse).

  • Incing (Instant Trigger): Automatically shuts off after a set time between 0.5 seconds and 1 hour after the device is switched on. Ideal for garage doors and valves.

Dry Contact and RF Remote Control Flexibility

The most strategic feature of this device is its dry contact output. Independent of the device's own power supply, you can trigger lines at different voltages (AC or DC). Furthermore, thanks to 433MHz RF remote control support, you can continue to control your devices locally even if the internet connection is interrupted.

High Capacity and Easy Assembly

With a load capacity of 10A (2200W) per channel and a total of 40A (8800W) , it can handle even the heaviest loads. Its DIN rail support design allows for professional-standard mounting in industrial electrical panels in seconds.
