Analog Wiring
Consider the following when wiring your analog modules:
• The analog common (COM) is not connected to earth ground inside the
module. All terminals are electrically isolated from the system.
• Channels are not isolated from each other.
• Use Belden 8761, or equivalent, shielded wire.
• Under normal conditions, the drain wire (shield) should be connected to
the metal mounting panel (earth ground). Keep the shield connection to
earth ground as short as possible.
• To ensure optimum accuracy for voltage type inputs, limit overall cable
impedance by keeping all analog cables as short as possible. Locate the
I/O system as close to your voltage type sensors or actuators as
possible.
• The module does not provide loop power for analog inputs. Use a
power supply that matches the input transmitter specifications.
