Mixed connection of ID-Lite analog inputs:
AI1 – binary input
AI2 – three state input
AI3 – analog resistive input
Analog inputs are designed for resistive sensors with resistance in range of 0Ω to 2,4kΩ.
To ensure a proper function use shielded cables, especially for length over >3m.
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 ID-Lite analog inputs because of influencing by ID-Lite analog input.
As binary input
Open, close state are detected, threshold level is 750 Ω.
As three state input
Open, close and failure state are detected. Threshold level is 750 Ω, failure is detected when circuit
resistance is <10 Ω or > 2400 Ω.
