The rH-R1S1 LR module is a combination of a relay and a contact input. The module sends information about the opening and closing of contacts to the system and controls the relay, which can switch on any electrical circuits. Communication with the server takes place via radio. The module has a physical input for connecting one monostable potential-free contact and one relay input. The load of the relay contacts can be resistive, inductive or capacitive, both in DC and AC circuits. The rH-R1S1 module is particularly suitable for controlling the fan, lighting or for switching off the electrical socket. The module has a much greater transmission range (up to 300 m) compared to the rH-R1S1 equivalent
