Avoid Power Related Damage Using Overcurrent Protection with a Multiple Output Power Supply
When multiple voltages power a device, it is often desirable to turn off all the power supply outputs when a fault occurs. If using more than one power supply, daisy chain the digital IO ports such that all outputs, even across mainframes, will be shut down on an overcurrent event. Provide additional protection for a device by using these three functions together - OCP, fault-out and the inhibit function - to shut down all the outputs.
