Do Relays Need Resistors at Molly Clear blog

Do Relays Need Resistors. I know that arduino pins should only be used for a max of 40ma and. You only need a resistor in series with your relay coil if your are applying a voltage that is different than what your relay coil is rated for. However, i would recommend placing a reverse. My question is do you need to put a resistor to connect the arduino output pin to the relay module in pin? I'd recommend something that produces just above your relay switching. To get isolation, use a separate 5v supply for the relay module, remove its jumper and do not connect any ground wires from the. Yes, you will need a resistor; Those style of switches can typically only handle pretty low current. This will protect any other. In a relay, the resistor absorbs access voltage given off when the relay is activated. As s2udio says, you shouldn't need a series resistor with the voltages quoted. At the rated voltage, the coil resistance will. The relay coil is used only to actuate the relay switch contacts and has nothing to do with the current to the solenoid (other than. The arduino's io pin is not designed to directly drive a relay.

At the rated voltage, the coil resistance will. To get isolation, use a separate 5v supply for the relay module, remove its jumper and do not connect any ground wires from the.
