PSQ-AMS
The smart quarter-turn actuator up to 1000 Nm
PSQ-AMS is the patented smart actuator solution up to 1000 Nm torque for modulating control valve
applications. PSQ-AMS includes enhanced electronics with an embedded micro-controller with flash
memory that controls and monitors the entire actuator function. Summarizing all functions on a single circuit board makes the actuator extremely compact and safe in operation. The value for money
is outstanding.
The PSQ-AMS is based on a robust and efficient
Wolfrom gear. This gear allows manual operation
at any time, without clutch or switch.
A PSQ-AMS is installed fast due to the automated one-key commissioning.

The diagonistic and monitoring function gives
information about the state of the operating valve.
Due to the softstart function, a PSQ-AMS is valve
friendly and therefore supports a high process
demand. A starting torque of up to 30% above
nominal torque may also be set.

The PSQ-AMS is programmable via
the optional local control or via USB
interface. The control offers a series of
standard features:
•tAll common interfaces are
t integrated, fieldbus is optional
•tIntegrated position indicators and
t valve positioner functionalities
•tValve control curve is adjustable
•tSplitrange control is possible too

Optional accessories
PSQ-AMS actuators from PS Automation have a modular concept. The functions can be extended
with accessories.
Additional status signal
Possible by using potential-free additional limit
switches/ intermediate position switches.
Integrated process controller
Enables the independant control of a process,
without the need for an external controller. The
specification of the process setpoint is made via
fieldbus or an analogue signal (mA or V). 24 V DC
sensor power supply is integrated.
Terminal box
Connection of power supply and signals via Harting plug-in an IP68 box.

Power failure backup
Integrated emergency supply on basis of supercapacitors. Enables the actuator to have an emergency operation in case of power failure in a freely
adjustable safety position.
Local control
Enables manual operation and the access to
parameters and diagnosis on site without needing
a PC. Moreover, the valve position is shown in an
illumiated display.
