Relay User Manual

Updated January 27, 2021

Relay is a wireless, low-voltage relay featuring potential-free (dry) contacts. Use
Relay to remotely switch on/off appliances powered by a 7–24 V DC source. Relay
can operate both in pulse and bistable mode. The device communicates with a hub
via 

 radio protocol. In the line of sight, the communication distance is up to

1,000 m.

Regardless of the type of electrical circuit, only a qualified electrician should install Relay!

The Relay contacts are not galvanically connected to the device itself, so they can
be connected to the input control circuits of various equipment to imitate a button,
toggle switch, etc.
