Description

Specifications
User Manual
The analog I/O interface is the green terminal. It is used to set or measure voltage (0-
10V) or current (4-20mA) to and from other equipment.
The following directions is recommended to achieve the highest accuracy.
•
Use the AG terminal closest to the I/O. The pair share a common mode filter.
•
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 equipment that works in current mode. Current signals are less sensitive to
interferences.
In the GUI you can select input modes. The electrical specifications are shown below.
