50 Electrical installation
Voltage and current connection for analog inputs
Bipolar voltage (-10…10 V) and current (-20…20 mA) are also possible. If a bipolar
connection is used instead of a unipolar one, see section
on page
for how to set parameters accordingly.
PNP and NPN configuration for digital inputs
You can wire the digital input terminals in either a PNP or NPN configuration.
External power supply for digital inputs
For using an ex24 V supply for the digital inputs, see the figure below.
Frequency input
If DI5 is used as a frequency input, see section
on page
for how
to set parameters accordingly.
