Radio and electrical constructors, sets.IndicatorsThe radio designer "Start-7216" (musical signaling device) has been producing the Rivne plant named after V.I. 60th anniversary of October. Contains a case, a printed circuit board and parts from which, according to the attached instructions, you can assemble a musical signaling device - a device that emits a signal reminiscent of birdsong. The signaling device is made on nine KT315 transistors. The sound signal is generated by a piezoceramic emitter of the ZP-3 type. The device control unit allows you to either give a signal only when the button is pressed, the contacts of a switch are closed, or within about 5 seconds after a short press on the button. In the description of the RK, various options for using the signaling device are given. It can, for example, be used as a sensor for the presence of moisture, the level of water in the reservoir, the degree of wetness of the fabric, etc. The signaling device is powered from the Krona battery, which is located inside the case. The supply voltage can be in the range from 9 to 15 V. The consumed current does not exceed 80 mA. The dimensions of the structure are 125x94x35 mm, the weight is 200 g. The price is 7 rubles.
