Reliable Rotary Electric Actuator

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.

Beck’s patented CPS-5 technology has been providing reliable control feedback with infinite resolution in our products for many years.

Notable features include:

• 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.

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.
