3.2.5 3 Opto Outputs
The optocoupler outputs have one common potential (GND), separated from the common potential of the
input group.
Connecting method
4-pin plug-in terminal block
Cable
Shielded, max. 50 m
Number of outputs
3
Output signal
External supply required
Output current
Max. 30 mA
Output voltage
Max. switching voltage: 30 V
Potential isolation
Yes, 3 outputs have got 1 common
minus potential
Example: relay control connection
When output 1 is active (true), the relay switches.
For protection of the output circuit, relays with
free-wheel diode must be provided.
Example: voltage output connection
When output 1 is active (true), the output voltage
changes from 24/12 V DC into <3 V DC.
A load resistance of 2.2/1 k¥ must be provided.
