In this case, sensors with current loop output (4-20mA) can be connected to the
device as shown in the following figure.
The input impedance value of each track is 62Ω.
Do not exceed the signal limit for each case (10 V or 20 mA respectively).
Excessive signal level may cause abnormal operation or permanent damage to the device.
