The output CRF Kl. X2A.7 may
be loaded with maximal 6mA!
Depending on the selected interface (An.0/An.10) the analog inputs AN1 and AN2
can process following input signals:
An.0 / An.10= 0

Interface Selection
(An.20)
With An.20 it is determined from where the 3. analog setpoint signal is received.
Following values can be defined:
Value Function
0
Analog value from the optional analog input (default)
1
Analog value via the terminals of AN1
Ri = 55 kOhm
