sources and the MIC-3716.
w
The signal cables must be kept away from strong electromagnetic
sources such as power lines, large electric motors, circuit breakers
or welding machines, since they may cause strong electromagnetic
interference. Keep the analog signal cables away from any video
monitor, since it can significantly affect a data acquisition system.
w
If the cable travels through an area with significant
electromagnetic interference, you should adopt individually
shielded, twisted-pair wires as the analog input cable. This type of
cable has its signal wires twisted together and shielded with a
metal mesh. The metal mesh should only be connected to one
point at the signal source ground.
w
Avoid running the signal cables through any conduit that might
have power lines in it.
w
If you have to place your signal cable parallel to a power line that
has a high voltage or high current running through it, try to keep a
safe distance between them. Or, you should place the signal cable
at a right angle to the power line to minimize undesirable effects.
w
The signals transmitted on the cable will be directly affected by
the quality of the cable. In order to ensure better signal quality, we
recommend that you use the PCL-10168 shielded cable available
from Advantech.
