Control Electronics – 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), 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)).

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 lance the two signals.

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:

  • Pre-Determined Action Upon Loss of Input Signal
  • Stall Protection
  • Split Signal Operation for Control of Multiple Drives
  • Temperature Sensing with Alarm

Digital Control Module
(DCM-3)

Beck’s DCM-3 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-5)

Beck’s patented CPS-5 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-5)

The analog Electronic Signal Receiver (ESR-5), 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-3.
