GROUP 11 QUARTER-TURN ROTARY ACTUATORS

MODEL 11-200

Experience unparalleled precision in process control with the Harold Beck Model 11-200. Engineered for seamless linkage connection to valves and dampers, this industrial quarter-turn rotary actuator is built to thrive in high-cycle environments where pneumatic alternatives fail. By utilizing a unique no-burnout motor design, the 11-200 provides continuous modulation and instant response without the risk of overheating, ensuring your control loops remain stable and efficient under the most demanding duty cycles.

Constructed with a rugged, NEMA 4X cast aluminum enclosure, the Model 11-200 protects its precision-machined alloy steel gear train from harsh industrial elements. The integration of patented contactless position sensing technology offers infinite resolution and eliminates the wear-and-tear associated with traditional potentiometers. Whether you are managing combustion air dampers or large process valves, this actuator delivers the reliable, maintenance-free performance that has defined the Beck legacy for decades.

Performance and Reliability Features:

  • Precision modulation with high-speed response reaching full torque in under 50 milliseconds.
  • Maintenance-free gear train with self-locking mechanisms to hold position upon power loss.
  • Contactless position sensor technology ensures signal accuracy without mechanical wear.
  • Integrated electric handswitch and manual handwheel for effortless local operation and troubleshooting.
  • Advanced digital control module featuring HART protocol compatibility for smart diagnostics.
  • Weatherproof NEMA 4X housing designed for extreme temperatures from -40 to 185 degrees Fahrenheit.

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.

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.

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.
