Compatibility Issues of DIO
z While it is possible to use a standalone or a summable power supply with a DIO
drop (as long as the DIO input is left unpowered), it is not possible to use a
redundant supply with the DIO drop.
z
The added power supply must not be included in the system I/O map.
z
The added power supply need not be of the same type as the DIO adapter. AC
powered supplies may be used with DC type adapters and vice-versa.
z
DIO module current load with an added power supply is typically 200 mA.
