I suppose I was concerned that the digital output pin on the Arduino can produce up to 40mA which is greater than the Maximum Input Current of 20mA for the relay. Am I right in thinking this?
Hi ArrchThanks for the reply. I apologise for basic electronic knowledge. So what you are saying is that the Maximum Input Current of the relay is really the current that the relay requires to work ie 20mA? The fact that the Arduino can produce up to 40mA is irrelevant as it will supply what the relay requires? It will not damage the relay?In addition, I have read that I can directly connect the Solid State Relay (SSR) to the Arduino digital output pin?Really appreciate your help.RegardsWN
