• Input for position set-point value
7)
(4 – 20 mA corresponds to 0 – 100 %
(depending on position of DIP switch 1)).
• Digital input
7)
If a voltage > 10 V is applied, safety position (SAFEPOS) is activated, i.e. the valve is moved to the safety
position (factory setting, can be changed with communications software).
• Analog position feedback (variant)
7)
The position of the valve can be transmitted via an analog 4 – 20 mA output to the PLC
(4 – 20 mA corresponds to 0 – 100 %).
7) Only for variant without eldbus communication.
