Information About LM24A-MOD
The LM24A-MOD is a Belimo communicative rotary actuator with a universal shaft clamp suitable for damper shafts from 6 to 20 mm. The actuator provides a 95° rotation angle and a nominal running time of 150 seconds per 90°, with an adjustable running time range of 35 to 150 seconds. It includes a lockable push-button manual override and selectable direction of rotation. The unit is designed for stationary HVAC applications and has IP54 protection, NEMA 2 enclosure protection, and maintenance-free operation.
Key Features:
- Rotary Actuator: Provides controlled rotary movement for HVAC air damper applications.
- 5 Nm Torque: Delivers 45 in-lb of torque for positioning compatible dampers.
- 24 VAC/DC Operation: Uses a 24 V AC or DC power supply for building automation installations.
- BACnet MS/TP Communication: Supports direct integration with compatible BACnet building automation networks.
- Modbus RTU Communication: Provides Modbus communication for monitoring and controlling the actuator.
- MP-Bus Compatibility: Supports Belimo MP-Bus communication for actuator networking and system integration.
- Adjustable Running Time: Allows the motor running time to be configured from 35 to 150 seconds.
- Manual Override: Includes a push-button manual override that can be locked during servicing or commissioning.
The LM24A-MOD delivers the reliability and precision required for HVAC damper control, building automation, air-handling equipment, and commercial ventilation systems.
