WebOct 17, 2024 · Higher current-carrying capacity of the main contacts of the contactor. Auxiliary contacts (with the same function as the relay contacts) usually have a lower load capacity. Lower current carrying capacity of relay contacts. The operating current of relay contacts usually ranges from 0.5 to 10A. Relatively lower switching life. WebIn this tutorial, we will test out the four relays on board the Arduino 4 Relays Shield. This shield is a great addon for the Arduino UNO board, as it has four relays capable of handling loads up to 48V. To control the relays, we need to use the following pins: Relay 1 - pin 4. Relay 2 - pin 7. Relay 3 - pin 8. Relay 4 - pin 12. the meaning behind the name maria
