●
SSD161S.05DU (fail-in-place), and SSD161S.25DU (fail-safe): Operating voltage
AC/DC 24 V, modulating control signal DC 0...10 V
●
SSD131.29U (fail-safe): Operating voltage AC 24 V, 3-position (floating) control
signal
●
All actuators are self-calibrating to the valve stroke
●
Modulating variants have position feedback signal
●
Modulating variants are DIP switch configurable for equal percentage/linear flow
characteristic, direct/reverse acting, and the fail-safe variant for fail up/fail down
●
3-position (floating) fail-safe variant is DIP switch configurable for fail up/fail down
●
Direct mounting with coupling nut, no tools required
●
Manual override
●
Position and actuator motion indication (LED)
●
Positioning force 67 lbf (300 N)

Typical application in chilled ceiling, VAV, unit ventilators, fan coil unit and other terminal unit applications ● Max.10 units of SSD161S.05DU, SSD161S.25DU can operate in parallel, provided the controller output suffices. ● For 3-position actuator, SSD131.29U, 24 actuators can run in parallel. -
Page 3: Led Indication
DC 0...10 V control signal (for SSD161S.25DU, SSD161S.05DU) ● The valve opens / closes in proportion to the con- trol signal at Y. The SSD161… actuators can be set to either a linear or equal percentage control signal response, depending on the position of the associated flow characteristic DIP switch. -
