3.1.4 Optocoupler Inputs
The 3 optocoupler inputs have one common potential (GND) for the input group that is separated from the
common potential of the output group.
Connection method
4-pin plug-in terminal block
Cable
Shielded, max. 50 m
Number of outputs
3
Input signal
External supply required
10…28 V DC for 'high' level
0…5 V DC for 'low' level
Input voltage
Max. 28 V DC
Input current
<11 mA @ 24 V DC
<5 mA @ 12 V DC
Electrical isolation
Yes; a common minus potential for the group
of 3 inputs
Example: contact input connection
When a voltage ≥10 V DC is applied to the terminals (in the
example:1-GND), input 1 is active (true).
