Just got a good tid bit of info from Ruida.

The STATUS, and most likely most of the outputs, are rated for 500mA max, but the working current should be at or below 200mA for long life.

We were discussing the 6445, but I would probably apply this to most of the controller(s) isolated outputs.

Thank you for that info. I’ll make sure to wire everything to relays and not directly.
