Product Details

For fail-safe modulating control of dampers in HVAC systems, this BELIMO spring return damper actuator, 24VAC/DC is mounted directly to a damper shaft up to 1.05” dia. using its universal clamp. Model operates in response to a 2 to 10VDC, or with the addition of a 500 Ω resistor (not included), a 4 to 20mA control input from an electronic controller or positioner. A 2 to 10VDC feedback signal is provided for position indication. The actuator can provide up to 95° of rotation and is provided with a graduated position indicator showing 0° to 95°. Model uses a brushless DC motor that’s controlled by an Application Specific Integrated Circuit (ASIC) and a microprocessor. The ASIC can monitor and control the motor’s rotation and it provides a digital rotation sensing (DRS) function to prevent damage to the actuator in a stall condition.
