Arduino 4 Relays Shield

/9/2018So if I want to turn a light ON, the Arduino closes the relay (on the relay board) during 150 milliseconds which creates an impulse and turns the impulse relay ON (the Arduino acts as push button). I guess I'd need a relay / contactor with these characteristics: Input = 5V DC Output = 220V AC relay type = optocoupler (the Arduino wouldn't
