  • Building a four channel SolidState Relay

    Hello,Thanks for a quick reply.Correct me if im wrong, but according to AQH3223 max INPUT is 6v. so i should be able to drive it straight from lets say arduino output without LED in the middle, without even using any resistor ? 3223 should take as much current as it needs, right ?

  • Building a four channel SolidState Relay

    Well actually im thinking how much current do i need to drive it .Im using PCF8574 Expander and it can deliver up to 20mA per channel with total 100mA for all of them at the same time.Let say like regular relay takes 80mA to drive coil - then i would need transistor for ich output to drive relayI would really like to avoid transistors and use expanders only, but the question is how much current does 39MF22 take to operate

    Hello Again,Do you know what is the current draw of 39MF22 ?
