rH-PWM2S2

Two-channel low-voltage PWM controller with two inputs of the F&Home RADIO system.
The rH-PWM2S2 module is a combination of two power regulators and two contact inputs. The module sends information about opening or closing of the contacts to the system and controls two low voltage receivers powered from an external power supply (12V DC). The module has two electrical inputs for connecting two momentary potential-free contacts and two inputs for connecting receivers. Power control is performed by pulse width modulation (PWM) that switches the receiver. The pulse frequency is set in the range of 100 Hz to 1 kHz. Communication with the server is done by radio. The rH-PWM2S2 module is particularly suitable for controlling LEDs, switching electromagnetic locks and other low-voltage electromagnetic actuators.

AUTONOMOUS MODE: If the module is disconnected from the server, it goes into autonomous mode and starts to operate as a classic dimmer. Short press of the button connected to contact 1 or 2 switches on or off the first or the second output of the PWM respectively. Long press of the button increases/decreases power, in steps of 10% in the range of 10%-100%. Conditions for autonomous mode to activate: Correct connection of S1 and S2 contact with the button and Option Offline: autonomous mode enabled in the Installer settings.

The rH-PWM2S2 module is represented by an object, which consist of two LIGHT-type channels that read information about power and activation time from four identical inputs. The algorithm determines the maximum power read from all inputs and, along with the switch-on time, controls the connected lamp or other receiver. Feedback about the actual level of load control is applied on the “Confirmed PWM status” output. The element has also two binary (bistate) inputs and two binary outputs, separate for each physical input. Closing or opening the contact causes the logical state to change at the corresponding output.
