Notes on the inputs/outputs:
• Digital outputs (DO): with changeover contacts, freely parameterizable, e.g. for measuring
range identification
Load: 24 V AC/DC/1.7 A, isolated, non-sparking
• Digital inputs (DI): designed for 24 V, isolated, freely parameterizable, e.g. for autoranging
• Analog outputs (AO): 0/4 ... 20 mA, isolated; max. load 750 Ω
• Analog inputs (AI): 0/4 ... 20 mA, non-floating, internal resistance ≤ 100 Ω
Note
Display of connections AO1..3 on the LUI
The connections identified by AO1..3 are displayed on the LUI as AO11..13.
Note
Strain relief of the connecting cables
Make sure that the strain relief of the cable gland is not overloaded. Make sure that the
connecting cables are force-free.
If necessary, install an external strain relief.
Procedure for connecting
1. Open the center cover of the field control unit.
2. Open the cable gland using suitable tools.
3. Guide the connecting cables through the corresponding cable glands.
– Make sure in the enclosure that the cables are routed tidily and force-free.
– Use the clips provided in the enclosure.
