Group 29 Linear Valve Actuators
Beck Control Electronics
Group 29 Beck drives offer the benefit of a total control package,
utilizing reliable electronics to match the speed and precision of your
process instrumentation.
Standard Group 29 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.
Electronics Used on Model 29-109

Digital Control Module (DCM-2)
(used on model 29-109) |
Beck’s DCM-2 provides
modulating control 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-4)
(used on model 29-109) |
Beck’s patented CPS-4 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.
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 select Beck Control Electronics
- Pre-Determined Action Upon Loss of Input Signal
- Stall Protection
- Split Signal Operation for Control of Multiple Drives
- Temperature Sensing with alarm
