Hi,



I am using controlLogix 1756-PB75R powersupply module for a control logix chassis.
At site the power supply is fed from a retfier which is designed to have a positive 12v potential between common and Ground.
Across postive and common i read 24v dc.
Is this potential across common and ground is a problem for PLC and other cards in chassis ?
Thanks in advance.
