Edit Reason: Adding note about schematic not being useful for me, at my level of electronics knowledge
)
I've just tried attaching a load to the circuit (a small 24V light), connecting `-` (negative), `DC` (positive) and the light OUTPUT01.
The light goes correctly on/off in my case, but I noticed:
* when any of OUTPUT01~OUTPUT08 are enabled, all other non-enabled OUTPUT01~OUTPUT08 pins jump to 2.5V between `-` (negative) and the pin.
* same applies to OUTPUT09~OUTPUT16
* any pins attached to the load stay at around 0.5V between `-` (negative) and the pin
* the other pins stay at ~3.65V between `-` (negative) an the pin, when the pin with an attached load is disabled
In my case, this is mostly OK: I'm just worried about the amount of power that gets consumed passively this way, for a device that will sit in a rack, on 24/7...
EDIT: I'd love to help with the circuit schematic above, but I don't have the experience/knowledge for that, sorry :-\
