DUALR3 is a flush-mounted Wi-Fi smart dual relay switch module that is installed behind any standard switch to transfer it into a smart switch for wireless remote control with mobile devices or voice command.

Two-channel intelligent switch, which can be used to selectively control two different loads at the same time, or to manage a two-way electric motor for electric shutters (or similar).

The power supply (as well as the output) is the classic 100-240v alternating, while the maximum deliverable power is 10 Ampere per channel and 15 as a maximum sum.

If used to control roller shutter motors, the maximum load per channel is 1A (inductive load).

It has a terminal block with two contacts for the external connection of buttons and / or mechanical switches and three status LEDs, one blue relating to the status of the connectivity and two red ones relating to the status of the two channels. A small button on the back

• configuration of use (single or interlocked channels for use with motors for electric shutters or similar);
• timings (automatic on / off or automatic shutter adjustment).

NB: does not include the power and energy monitoring functions, nor the automatic overload protection nor the self-tuning function for electric motors.
