The five-channel relay rH-R5 contains five relays for switching electric circuits from a common power supply. Communication with the server takes place via radio. The load of the relay contacts can be resistive, inductive or capacitive, both in DC and AC circuits. All relays have one output of the NO contact connected to a common wire. The built-in temperature sensor protects the module against the effects of overheating. Pressing the button on the housing for less than 1s will switch on or off all relays simultaneously.
