Part number TF24-S US from Belimo, listed in Electric Actuators. KKM Solutions quotes this part with pricing and availability confirmed per order.

Power supply 24VAC 20%, 50/60Hz, 24VDC 10%. Power consumption running 2 W, holding 1.3 W. Transformer sizing 5 VA (class 2 power source). Electrical connection: (-S models have 2 cables) 3 ft, 18 GA appliance cable, 1/2 conduit connector. Overload protection electronic throughout 0 to 95 rotation. Torque min. 18 in-lb, for control of air dampers - Application - For On/Off, fail-safe control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer s 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 positionindicator 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 TF24-S US versions are provided with 1 built-in auxiliary switch. This SPDT switch is provided for safety interfacing or signaling, for example, for fan startup. The switching function is adjustable between 0 and 95 .. Belimo. Belimo. TF24-S US.
