The Delta Control Products DM24-210 is a non-spring return electric actuator designed for precise control of dampers and valves in HVAC systems. Operating on 24 VAC or 24 VDC power, this actuator provides a torque output of 210 in-lb (24 N·m), making it suitable for medium to large-sized dampers and valves. It accepts modulating control signals of 2-10 VDC or 4-20 mA, allowing for accurate positioning in response to varying input signals. The DM24-210 features a rotation range adjustable from 0 to 90 degrees in 5-degree increments, with a mechanical limit of 93 degrees. The actuator includes a manual gear release for easy manual positioning during installation or maintenance. Its compact design facilitates direct mounting onto round shafts up to 3/4 inch (20 mm) in diameter or square shafts up to 5/8 inch (16 mm), eliminating the need for additional linkages. The DM24-210 is housed in a NEMA 2, IP42-rated enclosure, providing protection against dust and light water spray, making it suitable for indoor applications.
