You have two options for the Control Unit power supply:
Supply from the Power Module
•
External supply via terminals 31 and 32 with 20.4 ... 28.8 VDC.
•
Use a power supply with protective extra low voltage (PELV according to EN 61800-5-1),
Class 2.
The 0 V of the power supply must be connected to the PE of the plant/system through a
low-ohmic connection.
The power supply is electrically isolated from the control terminals.

AI 0 and AI 1 can be switched over:
– 0 V ... 10 V or -10 V ... +10 V (voltage < 35 V)
– 0 mA ... 20 mA (120 Ω input resistance, voltage < 10 V, cur-
rent < 80 mA)
