Group 11 Rotary Damper Drives and Actuators
Beck Control Electronics
Group 11 rotary damper drives and actuators offer the benefit of a total control package, utilizing reliable electronics to match the speed and precision of your process instrumentation.
Standard Group 11 modulating drives (control option 9) are equipped
with Beck’s Digital Control Module (DCM-2), which controls the position of
the drive according to the input signal it receives. A position feedback
signal is delivered to the DCM from the position sensing device (Beck’s
Contactless Position Sensor (CPS-4). This signal is continuously compared
to the demand input signal. A change in the input signal results in an
immediate repositioning of the drive to balance the two signals.
Digital Control Module(DCM-2)
Beck’s DCM-2 provides modulating
control of the drive in response to
standard control system signals.
Notable features include:
- Convenient user interface
for calibration and drive
status.
- HART® compatibility.
- Compatible with common
asset management systems.
- Receives control signals
directly, eliminating the
need for contact protection
devices, relays, switches and reversing starters.
- Designed to operate continuously at temperatures from -40º F to
185º F (-40° to 85° C).
- Initiates shaft movement in steps ranging from 0.10% to 0.25%
of span, depending on the timing of the gear train.

Contactless Position Sensor (CPS-2)
Beck’s patented CPS-2 technology
has been providing reliable control
feedback with infinite resolution in
our products for many years.
- Utilizes a unique ferrite
magnetic design with no
contacting or wiping
surfaces to wear or
intermittently lose contact.
- The ferrite rotor is driven
directly by the output shaft
through anti-backlash
gearing.
- A 4–20 mA position
feedback signal is available
for remote indication.
Electronic Signal Receiver (ESR-4)
The analog Electronic Signal
Receiver (ESR-4), which is standard
in control option 7 and control option 8 drives, is
an alternative to the intelligent,
digital control module. The timeproven
ESR provides the same
excellent drive control but lacks
many added setup, operating, and
diagnostic features afforded by
the DCM-2.
Factory Calibration
All Beck drives are set-up and calibrated to the customer specification. No electrical adjustments are required before installation.
Additional Features available on Beck Control Electronics
