A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate the switch and provide electrical isolation between two circuits. - This 8 channel 12v relay has both optical and magnetic isolation, providing a lot of protection to the inputs from electrical faults on the outputs. - Works well with 12v logic (raspberry pi, arduino, teensy..), Requiring little current drive. - Breadboard friendly, using female/male dupont makes it extremely convenient for prototyping. - Led indicates its working status. Red refers to errors. - 3 terminals per spdt relay. All of these features make sainsmart relay a great component for automation projects. Item weight: 0.3 pounds
