DC 0...10 V control signal
● The valve opens / closes in proportion to the
control signal at Y.
● At DC 0 V, actuator stem is retracted, the normally
closed valve is fully closed and the normally open
valve is fully open.
● When no power is supplied, the SSC161.05U
actuator maintains its current position and the
SSC161.35U actuator fails with the stem fully
retracted.
● This actuator provides a DC 0…10 V position
feedback signal proportional to the stroke of the
actuator stem.
Y = Control signal Y [V]
H = Percentage of calibrated valve stroke
