Ansonic Radio receiver from EF 433 4 channel group A 230 volts

With a maximum of 4 potential-free, heavy-duty relays in the output, there are many possible uses. The receiver is particularly suitable for switching gate systems, lighting, alarm systems, fountains, etc.
Channel groups and frequency bands can be freely selected.

A frequency-modulated signal can be generated at high frequencies with the aid of an oscillator circuit whose frequency-determining resonant circuit contains a voltage-dependent capacitance, typically a capacitance diode, to which the modulation signal is applied as a signal voltage. This changes the capacitance of the diode and thus also the resonance frequency of the resonant circuit. FM at low frequencies is easier to generate with voltage controlled oscillators. A direct digital synthesis circuit (DDS) or quadrature amplitude modulation (IQ modulation) can advantageously be used for digital generation of a frequency-modulated signal.
