GROUP 11 MULTI-TURN ROTARY ACTUATOR

Model 11-480: Industrial Multi-Turn Rotary Actuator for Stem Valve Automation

The Harold Beck Model 11-480 is a robust multi-turn actuator specifically designed for rising and non-rising stem applications in diverse process industries. As part of the proven Group 11 family, this actuator provides the precise, reliable positioning required to optimize control loops and enhance system efficiency. Its unique motor design reaches full speed and torque in less than 50 milliseconds and stops within 25 milliseconds, eliminating the dead-time and overshooting common in lower-quality electric actuators.


Equipped with the DCM-3 Digital Control Module and Beck’s patented CPS-5 contactless position sensor, the Model 11-480 offers infinite resolution and consistent feedback without the mechanical wear of potentiometers. The unit's heavy-duty, all-spur gear train is housed in a multi-compartment NEMA 4X aluminum enclosure, ensuring that sensitive electronics stay protected during installation and maintenance. With self-locking mechanics and a no-oil-bath design, the 11-480 provides a versatile and maintenance-free solution for any orientation.


Advanced Engineering Specifications:

  • • Precise modulation with minimum step resolution of 0.1% to 0.25% of span.
  • • Patented contactless position sensing (CPS-5) ensures accurate feedback with zero mechanical wear.
  • • Durable alloy steel spur gear train with integral self-locking for secure position holding.
  • • Multi-compartment NEMA 4X enclosure for superior protection and easy component access.
  • • HART® compatibility and advanced diagnostics via the Digital Control Module (DCM-3).
  • • Built-in stall protection and temperature sensing with configurable alarm functionality.

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.

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

BECK DRIVE MOTOR: PRECISE, RELIABLE CONTROL

Together with Beck’s control electronics and rugged gear train, Beck motors provide the precise, reliable positioning required for modern control loops.

  • Never overheats or burns out, even under demanding modulating control or stalled conditions.
  • Reaches full speed and torque in less than 50 milliseconds and stops within 25 milliseconds, eliminating deadtime.
  • Provides extremely accurate positioning in modulating applications.
  • Will not coast or overshoot the desired position.
  • Low current draw of 0.16 A to 3.0 A, and therefore low power consumption, eliminates the need for relays and permits the use of uninterruptible power supplies.
  • Maintenance-free with double-lipped, grease-sealed bearings.
ELECTRIC HANDSWITCH: TIME-SAVING LOCAL OPERATION

Dampers or valves may be operated at their individual locations with the built-in electric Handswitch. This saves time during installation and troubleshooting, allowing on-line adjustments to be made quickly and easily by bypassing the electronics in the drive and control system.

The Handswitch also serves as an electrical backup in the event of control system failure.

AUXILIARY AND OVER-TRAVEL LIMIT SWITCHES

Two over-travel limit switches and up to four auxiliary switches are provided on Beck drives.

  • SPDT switches rated for a minimum of 6 A at 120 V ac, (three times maximum motor current for most models) to ensure long life.
  • Field-adjustable to operate at any point in the drive’s travel range.
  • May initiate secondary functions or provide remote indication of drive position.
  • Eliminates unreliable and maintenance- intensive proximity switches.

DRIVE TRAIN: DURABLE AND EFFICIENT

Beck’s durable gear train maintains accurate, consistent control element positioning even under the demanding conditions of an active control loop.

  • Gear trains employ a unique, all spur gear construction of heat-treated alloy steels and ductile iron.
  • Efficient, wide-face spur gearing virtually eliminates wear-induced backlash and positioning inaccuracies.
  • Durable design provides up to 4 days of protection against intermittent or extended accidental stalls.
  • Integral self-locking mechanism ensures that drives hold a load with the motor de-energized.
MANUAL HANDWHEEL: CONVENIENT MANUAL CONTROL WITHOUT DECLUTCH

An easy-to-turn, spoke-free Handwheel is incorporated into the Group 11 design to allow manual operation during installation or power outages.

  • Move valves and dampers to any position smoothly and easily without power, even under full load conditions.
  • Mechanical stops in housing prevent manual overtravel.
HOUSING: SUPERIOR PROTECTION WITH CONVENIENT ACCESS TO COMPONENTS

individual compartments

Beck drives feature a cast aluminum body with individual compartments to protect components from moisture and dirt, and allow easy access for installation and calibration.

  • Precision-machined aluminum alloy castings with corrosionresistant poly-urethane paint provide a rugged, dust-tight, weatherproof NEMA 4X enclosure.
  • Individual compartments protect all major components: Motor, DCM, CPS-2, gear train and installation wiring terminal board.
  • Each compartment can be accessed without exposing other components.
MOUNTING VERSATILITY: MOUNT IN ANY ORIENTATION FOR GREATER INSTALLATION FLEXIBILITY

Group 11 Beck drives are designed to be mounted in any convenient position. The no oil bath design eliminates the potential for leaks.

As long as housing compartments remain accessible, there are no mounting orientation limits.

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, 11-430, or 11-480. 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.
