<p>The relay's electronic circuit, in summary, consists of: a) adjustment section, b) programming section, c) control section. The adjustment section consists of the voltage divider R1-R2, a rectifier bridge and the normalisation elements C1-R2. The input of the present section that simultaneously is the relay's input, can accept any voltage AC suitable for the activation of the relay. The programming section is located between levels aa' and bb'. It is the main digital section of the circuit and in the case of a four contact relay, it consists of eight Schmitt-Trigger Inverter gates, four Buffers and eight switches. The third section of the circuit is the relay's control section and comprises of four Optocouplers, certain resistances and condensers and four or eight TRIACs depending on the application. The main advantage of the relay of the current invention is the possibility of controlling any AC and DC loads with any power elements and operating voltage thereof. The capability of simultaneously having both AC and DC loads on the same relay.</p> |
