Honeywell Direct Coupled 30 in-lb. Spring Return - MS4104F1010/U

The Honeywell Direct Coupled 30 in-lb. Spring Return is a high-performing and versatile actuator rated at 120 VAC and 21.6 VA. Benefitting from a two-position, single pole, single throw (SPST) feature, it is designed to operate with utmost consistency in smoke control systems and has garnered Underwriters Laboratories Inc. UL555S ratings at temperatures up to 350 degrees Fahrenheit.

One of its most impressive features is the reversible mounting that smoothly operates in either clockwise or counterclockwise spring rotation. Its housing design promotes flush mounting to the damper, offering convenience during installation.

Models equipped with SPST position-indicating switches are available, providing additional functionality with 7-degree and 85-degree stroke options. Enhanced by an integral spring return system, a level of return torque is guaranteed, matched by a swift, fifteen-second spring return timing. The device performs proficiently without requiring special cycling during long-term holding, and significantly, doesn't produce audible noise during this process.

The ingenuity of its patent-pending design removes the necessity for limit switches, effectively reducing power consumption. With models designed for 24, 120, and 230 VAC, this controller is suitable for a broad range of applications. Offering a ninety-five degree angle of rotation, the actuator maintains its rated torque even at diminished power levels.

Technical specifications include a power consumption of 21.6 VA and a resilient operating condition range from 0 degrees Fahrenheit to 130 degrees Fahrenheit, or -18 degrees Celsius to 55 degrees Celsius. Its electrical connection features color-coded leads for easy identification, while its robust aluminum housing guarantees durability. For rotation, it functions in a clockwise pattern, while the spring return operates in a counterclockwise pattern.
