Recting sound signal, 24 V

The sound signal power is 95 dB (at a distance of 10 cm). The supply voltage is in a wide range of 3 to 24V. The module contains a built -in generator of interrupted oscillations, which greatly simplifies the task of the developer to generate pulses. The frequency of 3100 Hz ± 500 Hz is optimal for guaranteed perception by the human ear at considerable distances. On the device’s case, the mounting holes are located at a distance along the axes of 40 mm, the power is carried out in two wires (105 mm length). At a 12V supply voltage, the consumption current is 20ma. The module works as an independent device.
