Trust PAC to show a non-conventionally wired relay - ie, suppression diode line/Cathode to 85 (because their 86 is GND).
But yes, the AX supplies 10A or whatever power its supply can source.
Because the others can only supply 1A, you have that drive a relay if more current is required.
But why not simply use a cheap 15A or 30A (micro) relay? If you want the other features, then of course I understand.
