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 Programmable analog
inputs on page 107 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 external +24 V supply for the digital inputs, see the figure below.
