Information About NM24A-SR
The NM24A-SR belongs to Belimo’s NM series of non-fail-safe damper actuators and is designed for direct mounting on HVAC damper shafts. Its universal shaft clamp accommodates shafts from 8 to 26.7 mm and includes an anti-rotation mechanism for secure installation. The actuator provides adjustable rotation up to 95° and includes a push-button manual override that can be locked. Its IP54 enclosure and operating range of -30°C to 50°C support use in a range of commercial HVAC environments.
Key Features:
- 10 Nm Torque: Provides the required driving force for compatible HVAC damper applications.
- Proportional Control: Uses a DC 2–10 V control signal for adjustable damper positioning.
- 24 V Supply: Operates from 24 VAC or 24 VDC power.
- Non-Spring Return: Maintains the commanded damper position without spring-return operation.
- 150-Second Running Time: Completes a 90° rotation in approximately 150 seconds.
- Universal Shaft Clamp: Fits damper shafts from 8 to 26.7 mm in diameter.
- Manual Override: Push-button mechanism allows manual positioning and can be locked.
- IP54 Protection: Provides protection suitable for standard HVAC actuator installations.
The NM24A-SR delivers the reliability and precision required for proportional air damper control in HVAC and building automation systems.
