5.1.4 Current output transducers
ID-Lite analog inputs are mainly designed for resistor sensors
In special case transducers to 4-20 mA output can be used for oil measuring (10.0 Bar or 6.0 Bar). Use
predefined 4-20 mA / 100 or 4-20 mA / 60 sensors.
This method reduces the input resolution by less than 50%
Some types of transducers are not suitable for connection to ID-Lite analog inputs because of influencing by ID-
Lite analog input.
Default current sensor characteristic
Use with external resistor 120 Ω.

5.1.5 Analog input extension measurement
On each analog input there is a possibility to connect voltage or current output sensor instead of resistive one.
Recommended wiring connection for these measurements are bellow.
