K8055 Analogue output question

Hi,
I have been unable to find any 5V DC relay that can be switched by the DAC voltage on the K8055. Presumably this is because 3mA is the max. I have got around this by using the digital output with an external power supply but I would like to simplify this and use the board’s own voltage. Any suggestions?

Maybe you can use a properly sized [color=#0000BF]Solid State Relay[/color]

Thanks.
For a basic switch it seems that I can just use a NPN transistor. :laughing:
