DC 0...10 V control signal (for SSA161.05HF)
● The valve opens / closes in proportion to the con-
trol signal at Y.
● At DC 0 V, actuator stem extended, the valve is
fully closed.
● When no power is supplied, the actuator maintains
its current position.
● This actuator provides a DC 0…10 V position feed-
back signal proportional to the stroke of the actua-
tor stem.
Y = Control signal Y [V]
H = Percentage of calibrated valve stroke
DC 0...10 V control signal (for SSA161E.05HF)
Combi valves VPI46../VPP46.. in combination with SSA161E.05HF have equal-percentage
characteristics.
● The valve opens / closes in equal percentage ratio
to the control signal at Y.
● At DC 0 V, actuator stem extended, the valve is
fully closed.
● When no power is supplied, the actuator maintains
its current position.
● This actuator provides a DC 0…10V position feed-
back signal proportional to the stroke of the actua-
tor stem.
Y = Control signal Y [V]
H = Percentage of calibrated valve stroke
LED indication
Color Pattern Flashing interval Description
Green Flashing 0.1 s Self-calibration
0.5 s Actuator stem is moving.
Constant - Actuator stem reaches a set position. The
LED turns off after it is constantly on for five
seconds.
Green/red Flashing 0.5 s Manual operation
Red Constant - Error*
* Hint: calibration or power reset required.
