Terminal assignment at connection X480
The external 24 V supply must be sized for the currents of the digital
outputs.
There are the following connections on the terminal strip:
♦ 1 analog input with differential signal which can be used as a current
input and as a voltage input
♦ 2 analog inputs (single-ended), which can also be used as digital
inputs
♦ 2 analog outputs
