Connection of Electromagnetic Relay REN 33.

Connection of Electromagnetic Relay REN 33.The greatest advantage of electromagnetic relays is that one can manage electronic circuits with elements that consume maximum currents. A relay is controlled by small currents, namely the exclusive source of supply or elements of electronic circuits that produce a certain minimum voltage for current loads. The relay closure occurs when a minor current from the power source is passing through the relay coil. And there is remote control - turning on and off, i.e. the method of contact group switching. This type of relay keeps the operator absolutely safe from contact with high voltage. Each type of an electromagnetic relay is designed for the nominal operating voltage of the coil, its resistance, switching voltage and current of the contact group. These are the main indicators of the electromagnetic relay operating parameters.We will give you a practical example of a simple connection and use circuit of relay REN33 in not complicated surface-mounting ... .... To see this firsthand, we use a power supply with two devices with an arrow - a voltmeter and ammeter ... .. and we take two fans as a load that run on AC 220V ... ... Well, in the centre of our combined circuit is relay REN33, which is designed to work on voltage of 27 V, this is the rating for its reel ... ... .. I get around very well with a voltage of 12V, and it is quite enough for this unique device to operate.Connection of the assembly elements:12 V go from the power source to the outputs of the coil ... .... We connect both fans to one of the four relay contact groups ... ... turn on the power source ... and watch what is happening now, especially on the ammeter, which indicates the current consumption of the operational relay coil, namely, 60-70 mA ... .. and toggle the two fans ... ...
