Hello I'm looking for a relay that has a switch that can carry 12v at 1 or 2 amps. control pins has pull down circuit, can prevent wrong operation when on the float status. So we created the Plug & Play Arduino Relay. It is possible to control the Relay shield through Arduino/DFRduino using digital IOs with external 7 to 12V supply. Even so, with our wide-ranging selection it’s impossible to have every single variation of 12v actuators, therefore we offer custom orders with no minimum order quantity requirement. When I send the relay a digital write high command the corresponding LED on the relay gets dimmer but the relay itself doesn't switch. Another fantastic application of relays is when you want to use a low-power signal (think Arduino’s 5V, 50mA pins) to control a higher-power (240VAC if you are savvy) circuit. 2 amps of current to the relay coil closes contacts to feed power to an accessory that requires more current to operate, usually over 20 amps. ULN2003 used as Relay coil driver.
