The positioner Type 024.16.720 is a 3-wire device, i.e. the power (24 V DC) is supplied separately from
the set-point value signal.

(depending on position of DIP switch 1)).
•Binaryinput
If a voltage > 10 V is applied, SAFE POSITION is activated, i.e. the valve is moved to the safety position
(factory setting, can be changed with communications software).
