Belimo AM24 US Damper Actuator, On-Off Floating Point Control, Non-Spring Return, Direct Coupled, 24V - APPLICATIONS: For on-off and floating point control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturerÂ's specifications. The actuator is mounted directly to a damper shaft up to 3/4Â" in diameter by means of its universal clamp, or up to a 1.05Â" jackshaft with the optional K4-1 clamp. A crankarm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft. OPERATIONS: The actuator is not provided with and does not require any limit switches, but is electronically protected against overload. The angle of rotation is mechanically limited to 95°. When reaching the damper or actuator end position, the actuator automatically stops. The gears can be manually disengaged with a button on the actuator cover. The position of the actuator is indicated by a visual pointer. The anti-rotation strap supplied with the actuator will prevent lateral movement. The AM24-S US version is provided with two built-in auxiliary switches. These SPDT switches are provided for safety interfacing or signaling. The switching function is adjustable between 0 and 95°.
