Herculine 10260 Series Actuators

altHoneywell's Herculine 10260A medium-torque industrially rated rotary actuator is engineered for exceptional reliability, accurate positioning and low maintenance.

Honeywell's Herculine 10260S is the latest in a series of additions to the Herculine product line. Herculine 10260S Smart actuators incorporate the features of the traditional Herculine actuators with the added benefits of a microprocessor-based Enhanced Electronics Unit (EEU). These benefits make it easier to set up and maintain the actuator, and allow the customer to monitor the health of the actuator for proactive maintenance planning. 

Herculine 10260S Smart actuators enable operation at maximum process efficiency, minimal downtime and access to all actuator parameters for real-time decisions. Honeywell's 10260S actuators are industrial rated and engineered for very precise positioning of dampers and valves. The Herculine 10260S performs especially well in extremely demanding environments requiring continuous duty, high reliability and low maintenance. Typical applications are furnace pressure dampers, gas/air valves, windbox dampers, coal mill dampers and more.



  • Enclosure: Rugged, industrial grade enclosure
  • Low Maintenance: Simple, proven design means high reliability and low maintenance
  • Output Shaft Hardware: All 10260A series actuators are supplied with an adjustable radius and adjustable position crank arm. Optional 12" crank arm, linkage kits and direct coupling hardware are available.
  • Accurate Positioning: Motor/gear train provides accurate positioning with instantaneous start/stop characteristics
  • Non-Contact Position Sensing: Non-contacting sensing lowers maintenance costs and improves performance
  • Torque: High torque capability in small package (10 to 300 lb-ft of torque)
  • Output Signals: 0/4-20 mA, 0/1-5 Vdc (0-16 Vdc) and slidewire emulation
  • Power Requirements: Low power consumption 120/240Vac, 50/60 Hz, single phase < 1 amp
  • Full Travel Speed: Full stroke travel speeds from 10 to 60 seconds (90 degree travel, 60 Hz supply)
  • Manual Operation: All 10260A series actuators are supplied with a manual handwheel to operate the actuator when power is not available
  • Auto-Manual: Electric hand switch with auxiliary contacts indicating an "Out-of-Auto" position is available for local electric control
  • Non-Contact Position Sensing: Non-contacting sensing lowers maintenance costs and improves performance
  • The Slidewire Emulation Circuit (SEC): Emulates the proportional voltage output of a typical slidewire through a high impedance circuit. The voltage output is proportional to the supply voltage and shaft position. A noncontact position sensor is used to determine shaft position in place of the slidewire.


  • Duty Cycle: 100 percent duty cycle motor
  • Control Signals: 4-20 mA, 1-5 Vdc, position proportional (PAT), open/close (contact closure)
  • Limit Switches: All 10260A series actuators are supplied with two end-of-travel electric limit switches. Up to four additional SPDT auxiliary switches are available. 


  • Duty Cycle: Continuous dutycycle motor - no burnout
  • Limit Switches: Two end-of-travel electric limit switches are supplied as standard equipment with all 10260S series actuators
  • High Accuracy: Typically 0.25 percent of 90° span.
  • High repeatability: Typically 0.2 percent of 90° span
  • Characterization: Linear, square root or user-configured 21-point characterization allows tailoring of control for specific applications
  • Input Filter setting: Four programmable combinations of input filter settings are provided to accommodate customer's needs. The combinations are none, spike, low pass or spike + low pass filter
  • Deadband: Deadband is programmable between the values of 0.2 percent to 5 percent of 90° span
  • Control Signals: 0/4 to 20 mA, 0/1 to 5 Vdc, 0 to 10 Vdc, Digital remote setpoint (RS485 Modbus RTU protocol)
  • RS485/Modbus RTU Communication: Simple and easy to use Modbus RTU communication is standard with all 10260S actuators allowing seamless networking of Honeywell control products
  • HART Communication: Optional HART communications provides access to calibration, configuration and maintenance data. In addition, the HART communications option is structured to work with the HART asset management features.
  • Auxiliary Outputs: Two types of auxiliary outputs can be specified--SPDT switches or electromechanical relay outputs. Relay outputs can be programmed to output alarm conditions, provide control of other equipment or indicate status.
  • Alarm Functions: Alarms may be assigned to relay outputs or may be accessed through Modbus. Alarms can be triggered from stall, temperature limits, motor cycle count, out of automatic mode, digital input, position, input failure, position sensor failure, power up failure and more.
  • Local HMI Configuration: An integral keypad and high intensity display is available for nonintrusive local configuration of the actuator
  • Configuration Security: Password protection is provided, allowing users to lock out some, all or no groups of setup parameters to prevent tampering
  • Factory Calibration: Factory calibration is stored in non-volatile memory and can be restored via the local HMI at any time
  • Direction of Rotation: Direction of rotation on increasing input signal is programmable
  • Split Range Operation: Split range is programmable and infinitely adjustable
  • Digital Input Override: A digital input is provided and is programmable to provide override of all other input signals as an emergency override of control. The digital input can be programmed to drive the actuator open, closed, remain in place or to a user-specified position on contact closure.
  • Failsafe: When input signal exceeds high or low range limits (or input signal failure), the actuator can be programmed to drive open, closed, remain in place or drive to a user-specified position.
