The rH-R5 LR module 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 module has a much greater transmission range (up to 300m) compared to the equivalent rH-R5 F2250.
