4.5.4.7 Connection of Analog DC Inputs
The Unit possesses 2 analog DC inputs, whose input values can be dip-switch selected.
Three range intervals can be selected by the help of the dip-switches S1.1 to S1.4.
Input 1
Interval
S1.2
range:
0 - 10V
Off
0 - 5V
On
0 - 20mA
On
Table 5: Range Interval Selection for the Connection of Analog DC Inputs
The third analog input does not possess this selection opportunity; it has a fixed input voltage
range of 0 – 10V.
Figure 12: Connection Diagram for Analog DC Inputs
Note:
The initial value of the analog inputs can be increased to 4mA (and 1V or 2V, respectively)
by deploying the dip-switch S1.7.
This is necessary if e.g. a range interval of 4- 20mA is desired.
