Description
The Belimo NM24A-MOD is a non-spring return damper actuator engineered for demanding commercial HVAC and building automation applications. Operating on 24V AC/DC power, it delivers a robust 90 in-lb (10 Nm) torque output with a 150-second nominal runtime, providing reliable and precise damper control across a wide range of air handling and ventilation systems.
Equipped with both BACnet MS/TP and Modbus RTU communication protocols, the NM24A-MOD integrates seamlessly into modern building automation systems (BAS), enabling remote monitoring, commissioning, and diagnostics without additional hardware. This dual-protocol capability makes it an ideal choice for new construction and retrofit projects where open-protocol interoperability is required.
Key Features
- 24V AC/DC power supply for broad compatibility
- 90 in-lb (10 Nm) torque output for reliable damper actuation
- 150-second nominal runtime for smooth, controlled operation
- BACnet MS/TP and Modbus RTU dual communication protocols
- Non-spring return design for energy-efficient positioning
- Suitable for commercial HVAC air handling and ventilation dampers
- Supports open-protocol building automation system integration
- Compact, robust housing for easy installation and long service life
Communications & Integration
The NM24A-MOD supports BACnet MS/TP and Modbus RTU, two of the most widely adopted open communication standards in the building automation industry. This enables direct integration with a broad range of BAS controllers, simplifying commissioning and enabling real-time feedback on actuator position, fault status, and operating parameters.
Applications
- Commercial air handling units (AHUs)
- VAV and constant-volume ventilation systems
- Outdoor air and exhaust damper control
- Building automation and energy management systems
- Retrofit and new construction HVAC projects
