Information About NFX24-SR

The NFX24-SR is a Belimo fail-safe actuator designed to position HVAC dampers during normal operation and automatically return them to a defined safety position when power is lost. Its spring-return mechanism provides dependable fail-safe functionality, while the modulating interface enables proportional damper positioning. The actuator supports direct mounting to compatible damper shafts and provides position feedback for integration into HVAC control systems.

Key Features:

                                                                                                                      • Spring-Return Design: Automatically moves the damper to its fail-safe position following power loss.
                                                                                                                      • 90 in-lb Torque: Provides 10 Nm of motor and spring torque for compatible HVAC dampers.
                                                                                                                      • 24V Operation: Supports both 24 VAC and 24 VDC power supplies.
                                                                                                                      • Modulating Control: Uses a 2–10 VDC control signal for proportional damper positioning.
                                                                                                                      • Position Feedback: Provides a 2–10 VDC feedback signal for actuator position monitoring.
                                                                                                                      • Reversible Fail-Safe: Fail-safe direction can be configured for clockwise or counterclockwise operation through mounting orientation.
                                                                                                                      • Manual Override: Includes a hex crank for manual actuator positioning.
                                                                                                                      • Electronic Overload Protection: Protects the actuator throughout its operating rotation.

                                                                                                                      The NFX24-SR delivers the modulating damper positioning and fail-safe functionality required for HVAC airflow control applications.
