Hello,
I want to ask about the power consumption of the 1769-Pb4: It is written that the input power consumption at maximum load is equal to 100W. However, as I can see from its datasheet http://literature.rockwellautomation.com/idc/groups/literature/documents/in/1769-in028_-en-p.pdf (page 29), the pb4 can supply at 5Vdc 4amps and at 24vdc 2A. Doing a basic calculus, the output power of the pb4 is equal to 68W however its input consumes 100W. why there is a difference between the input power and output(32W)?
Thanks for your help
