Does anyone know if the PWM outputs (7&
are isolated from the MB system voltage?
I have a 24 VDC supply for the processor and motherboard, but my pump is 12VDC. I'd like to drive the 20W pump directly from the PWM output (well within the rating) without the need for some intermediate device. I thought I could feed 24 V to the power terminals and then use a separate 13.6 VDC supply (+ to the motor, return from the motor to Output 7 and then HIGH GND back to the separate supply.
Will this work or will I have a melt down?
