DC 0...10 V control signal (for SSA161E.05HF)
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
feedback signal proportional to the stroke of the
actuator stem.
Y = Control signal Y [V]
H = Percentage of calibrated valve stroke
