3.6 Wiring.
In the following pages some wiring examples with different types of parison controls are presented.
For the actuators which are equipped with a position current feedback signal of 4÷20 mA it has been indicated to
use a buffer to convert the current signal into a voltage signal. This is required because the analog input card 4 AI
6200 accepts only voltage signals.
It is possible to use a 500 Ω resistor to convert the current signal into a voltage signal that can be connected to the
analog input card. The following drawings help to clarify this application; note that one side of the resistor is
connected to input A and to the current signal coming from the actuator; the other side of the resistor is connected
to input B and to the signal zero volt.
For those actuators which have the same wiring arrangement but a voltage feedback instead of a
current feedback, it is possible to directly route the signal to the A pin of the relevant analog input
and connect pin B to the signal common as depicted in the following picture.
