Can any one give a rough idea of the power requirements for input channels? I am looking to size a power supply for the 200 inputs to an ABB PLC.
Thanks.
Thanks.

Hi
Simply define accuratly(from data sheets) the current consumption of each device supplied from this power supply.
Added all the values to know the total current consumption then take a factor of seftey around 20%.
Now your power supply configured
good luck

Most PLCs have power budget worksheets and power requirement data for each type of I/O card. If you don't find the info in your catalog, contact your distributor or manufacturer's representative.
