Group 22 Rotary Actuators
Beck Control Electronics
Group 22 Beck rotary actuators offer the benefit of a total control package,
utilizing reliable electronics to match the speed and precision of your
process instrumentation.
Standard Group 22 modulating drives are equipped with Beck’s Digital
Control Module, 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). 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.

Beck’s DCM provides modulating control of the drive in response to
standard control system signals. Notable features include:
- Convenient user interface for calibration and drive status (DCM-L).
- HART® compatibility is an available option (DCM-H).
- Compatible with common asset management systems (DCM-H).
- 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.

Control End complete with CPS-4 |
Contactless Position Sensor
Beck’s patented CPS 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.
- A 4–20 mA position
feedback signal is available
for remote indication.
Factory Calibration
All Beck drives are set-up and calibrated to the customer specification.
No electrical adjustments are required before installation.
