Harold-Beck - Model 11-300 -Rotary Damper Drives and Actuators
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 balance the two 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.
- 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.
CONTROL OPTION
Group 11 Beck drives have a model number such as 11-150, 11-160, 11-200, 11-260, 11-300, 11-360, 11-400, 11-460, or 11-430. Each of these drives has the capability to be equipped with different electronics combinations, which are called control options. The control option number will replace the last zero in the model number when specifying a drive model and control option. For example, a model 11-400 drive that is setup to use the control option 9 electronics would be considered a model 11-409 drive. A basic description for each control option is provided below.
