Analog inputs are designed for resistive sensors with resistance in range of 0
to 2,4k
.
To ensure a proper function use shielded cables, especially for length over >3m.
As binary input
Open, close state are detected, threshold level is 750
.
As three state input
Open, close and failure state are detected. Threshold level is 750
, failure is detected when circuit
resistance is <10
or > 2400
.

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

4.2.5 Analog input extension measurement (0 - 70V, 4 - 20mA)
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.
