Well pleased with these boards. All operated ok. Each relay is 75 ohms and draws 66 milliamperes. Use a separate 5 volt regulator to power them when operating with an arduino. Pulling down the input pin to common turns on the relay. I made a Bluetooth controlled arduino board that controls the relays as shown in my photo. The board has red leds to indicate which relay is turned on. You can replace the pin strip with a Molex connector, but its a tight fit with the pins.

I use these boards in many projects, they have good current handling relays, ttl input with high or low switching option, onboard indicator leds, pin header connections to dupont spacing standard for control and supply, and the relays themselves are quite efficient when energised with 5v version only 30ma each. My only gripe is the tongued screw terminals for switching side need opening up with a tool to get the wire in every time, they do however grip well without damaging strands, so not really a major issue.

ótimo preço e custo benefício, boa qualidade do material para o valor cobrado, mas o valor de tensão está errado, chegou pra mim relés de 12V e não 5V como eu pretendia recerber.

ótimos módulos de relé, usariam apenas para baixa corrente ou para acionar um contator para cargas mais altas, Ativo BAIXO, então você pode precisar usar um transistor para inverter o sinal de ativação proveniente do seu controlador se ele não puder afundar a corrente.

great relay modules, would only use for low current draws or to drive a contactor for higher loads, Active LOW so you might need to use a transistor to invert the enable signal coming from your controller if it can't sink current.
