Description: Belimo Actuator TFB120-S 120V NEW Application For on/off, fail-safe control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturers specifications. Control is on/off from an auxiliary contact, or a manual switch. The actuator is mounted directly to a damper shaft from 1/4 up to 1/2 in diameter by means of its universal clamp, 1/2 shaft centered at delivery. A crank arm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft. Operation The TF series actuators provide true spring return operation for reliable fail-safe application and positive close off on air tight dampers. The spring return system provides consistent torque to the damper with, and without, power applied to the actuator. The TF series provides 95 of rotation and is provided with a graduated position indicator showing 0 to 90. The actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches. Power consumption is reduced in holding mode. The actuator is double insulated so an electrical ground connection is not necessary. The TF-S versions are provided with one built-in auxiliary switch. This SPDT switch is provided for safety interfacing or signaling, for example, for fan start-up. The switching function is adjustable between 0 and 95.
