Damp.Linear, 101lbf, SR (2-10V), 24V| Application | For proportional modulation of dampers in HVAC systems. Actuator sizing should be
done in accordance with the damper manufacturer?s specifications.
The actuator operates in response to a 2 to 10 VDC, or with the addition of a
500 � resistor, a 4 to 20 mA control input from an electronic controller or positioner.
A 2 to 10 VDC feedback signal is provided for position indication or master-slave
applications. |

| Operation | The actuator is not provided with and does not require any limit switches, but is
electronically protected against overload. The anti-rotation strap supplied with the
actuator will prevent lateral movement.
The AHB(X)24 series provides 4 or 8 inches of linear stroke. The stroke of the gear
rack can be adjusted on both sides in increments of 0.8 in [20 mm] by means of the
mechanical end stops.
The stroke of the gear rack can be adjusted on both sides in increments of 0.8 in [20
mm] by means of the mechanical end stops.
When reaching the damper or actuator end position, the actuator automatically stops.
The gears can be manually disengaged with a button on the actuator cover.
The AHB(X)24-SR? actuators use a sensorless brushless DC motor, which is
controlled by an Application Specific Integrated Circuit (ASIC). The ASIC monitors and
controls the actuator?s rotation and provides a digital rotation sensing (DRS) function to
prevent damage to the actuator in a stall condition. Power consumption is reduced in
holding mode. |

| Typical Specification | Proportional control damper actuators shall be electronic type, with integrated linear stroking arm. Actuators must provide proportional damper control in response to a 2 to 10 VDC or, with the addition of a 500 � resistor, a 4 to 20 mA control input from an electronic controller or positioner. Actuators shall have brushless DC motor technology and be protected from overload at all angles of rotation. Actuators shall have reversing switch and manual override on the cover. Run time shall be constant and independent of torque. A 2 to 10 VDC feedback signal shall be provided for position indication. Actuators shall be cUL Approved, have a 5-year warranty, and be manufactured under ISO 9001 International Quality Control Standards. Actuators shall be as manufactured by Belimo. |
