Belimo TFX120 : Fail-Safe Damper Actuator, 22 in-lb Torque, 100-240VAC, On/Off Control Signal, 5-Year Warranty (Configurable)

Belimo TFX120 : Fail-Safe Damper Actuator, 22 in-lb Torque, 100-240VAC, On/Off Control Signal, 5-Year Warranty (Configurable)

The Belimo TFX120 Damper Actuator is a reliable solution designed for precise control of HVAC dampers. Operating on AC voltage between 100V and 240V, this actuator features a torque motor with 22 in-lb torque, reversible motion, and an adjustable auxiliary switch. The TFX120 is double-insulated and IP42-rated enclosure provides safety and protection against environmental elements. It complies with UL 2043 standards, making it suitable for use in air plenums under NEC Section 300.22(C) and IMC Section 602 regulations.

The TFX120 specifications include AC voltage ranging from 100 to 240V, a running power consumption of 2.5W, holding power consumption of 1.3W, and a torque of 22 in-lb. It operates on an On/Off control signal, with reversible motion selectable by ccw/cw mounting. The fail-safe mode has a rotation time of less than 25 seconds. The actuator is rated IP42 for protection, NEMA 2 for NEMA degree of protection, and UL Enclosure Type 2 for enclosure type. It operates in an ambient temperature range of -22 to 122°F (-30 to 50°C).

Designed for On/Off fail-safe control of dampers in HVAC systems, the actuator is mounted directly to a damper shaft with a diameter ranging from 1/4” to 1/2”.
