signals. In this case, only ground the cable at one end. Do not route signal lines
parallel to power cables.
Connect inductive loads to be switched via Pico outputs to a separate power feed,
or use a suppressor circuit for motors and valves. If loads such as motors, solenoid
valves or contactors are operated via the same power feed, switching may result in
interference on the analog input signals.
The following four circuits contain application examples for analog value
processing.
Ensure that the reference potential is connected. Connect the 0V of the power
supply unit for the different setpoint potentiometers and sensors to the 0V of the
power feed.
