• Use the same gnd (0V) for equipment and control box. The analog I/O is not galvanically
isolated from the control box.
• Use a shielded cable or twisted pairs. Connect the shield to the "GND" terminal at the
terminal called "Power".
• Use of equipment that works in current mode. Current signals are less sensitive to inter-
ferences.
Input modes can be selected in the GUI, see part II. The electrical specifications are shown below.
