I have a problem on an Analog Input Card on a PLC5.
The signal on one channel increases the value on other channels.
The inputs have different power supplies. The first three channels have a 4-20mA signal from pressure transducers having same power supply.
I add another 4-20mA from a temperature sensor. Now when I switch on power on the temperature sensor the pressure values on the other channels increase????
Please help!!!
