The rH-R3S3 module is a combination of three relays and three contact inputs with transmitters. The module sends information about the opening and closing of the contacts to the system and controls the relays, which can switch on any electrical circuits. The communication with the server takes place by means of radio.
The module has three physical inputs for the connection of three monostable potential free contacts as well as three relay switches. The load can be resistive, inductive or capacitive, in both AC and DC circuits.
Symbol in design and configuration software:
The rH-R3S3 module is represented by object that consists of three binary (two-state) inputs and three relay outputs. The inputs control the relays, and the outputs provide information about the state of the relays. Additionally, the object has three digital inputs and outputs. Shorting or opening of the contacts changes the logic states of the corresponding outputs.
  • Switch off the AC line and make sure that there is no voltage.
  • Mount the module on DIN rail (TH 35 mm).
  • Connect the wires according to the diagram above.
  • Switch on the AC line.
  • Register the device in the system.
An example application:
In the diagram above, the temperature and lighting sensor F1810 controls lighting and provides information on the current temperature. The illumination is compared with the comparator settings and depending on the result, the lamp on the first output of the F2233 relay is switched on or off.

F&HOME RADIO integrates electrical installations in such a way that the processes of heating, air conditioning, ventilation, lighting, alarm and access control form one efficient system - all for the safety and comfort of the residents. With wireless two-way communication between the central unit (server) and both sensors and actuators, software solutions, as well as remote control of the system that can performed by the users in many ways, the system allows them to manage home energy resources in a manner appropriate to their needs.
In practice, this means the ability to integrate electrical appliances in such a way that a hand gesture can create a romantic light scene in the living room and bedroom, pull down the shutters or blinds and adjust the interior temperature, for example. The option of remote control via the Internet ensures that even after our return from a long journey we are welcomed by the house as if we have never left.
