7.6 Analog input (AI1) or (AI2) – purple terminal block
Fig. 15: Analog In
Analog signal sources connected to terminals 12 and 13 for use with AI1 and connected to terminals 22 and
23 for use with AI2
Note correct polarity for signals 0 – 10 V, 2 – 10 V, 0 – 20 mA and 4 – 20 mA.
Use the pump to supply 24 V DC to an active sensor. For this purpose, pick off the voltage at +24 V (11) and
GND I (12) terminals.
NOTICE
The 24 V DC power supply is only available when the analog input AI1 or AI2 has been con-
figured for a type of use and a signal type.
