The rH-PWM2S2 module is a double PWM controller integrated with a double transmitter. The module sends information to the system about the opening or closing of two contacts and controls two low voltage receivers powered from an external source (12 VDC).

The module has two electrical inputs for the connection of two monostable potential free contacts, as well as two outputs for the connection of 12 VDC receivers. The power regulation is performed by pulse width modulation (PWM). The frequency of the pulses is set in the range 100 Hz to 1 kHz. The communication with the server takes place by radio.

The rH-PWM2S2 module is particularly suitable for controlling LEDs, electromagnetic locks and low voltage actuators.

The symbol of rH-PWM2S2

The rH-PWM2S2 module is represented by object that consists of two channels that read the power and time information from their inputs. The assigned algorithm limits the maximum power for each channel, and controls the connected devices (LEDs or other loads) in compliance with the start/stop times and attributed power levels. The confirmed status of each channel is provided on its output as a feedback. The element also has two inputs and two outputs, separate for each physical input. Shorting or opening a contact changes the logic state at the corresponding output (0/1).

A more advanced scheme for lighting control can be found in the Lighting control project article.

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.
