The Delta Control Products DMS24-180-Z is a non-spring return electric actuator designed for precise modulation of dampers and valves in HVAC systems. Operating on 24 VAC or 24 VDC power, it delivers a torque output of 180 in-lb (20 N·m), making it suitable for medium to large-sized applications. The actuator accepts modulating control signals of 2-10 VDC or 4-20 mA, allowing for accurate positioning in response to varying input signals. The “Z” designation indicates the inclusion of a Z-Span feature, enabling field adjustment of the control signal span to match specific system requirements. It is designed for direct mounting on round shafts up to 3/4 inch (20 mm) or square shafts up to 5/8 inch (16 mm), facilitating straightforward installation. The DMS24-180-Z is housed in a NEMA 2, IP42-rated enclosure, providing protection against dust and light water spray, suitable for indoor applications.
