Honeywell Direct Coupled 80 in-lb. Spring Return - MS4609F1010/U

The Honeywell Direct-Coupled 80-Inch-Pound Spring Return is a two-position SPST controller with a power rating of 29.9VA and a voltage rating of 230 VAC. Skillfully designed for reversible mounting, it can accommodate both clockwise and counterclockwise spring rotations. The distinctive housing design permits flush mounting to a damper, enhancing its functionality.

This controller is crafted to provide reliable operations even in smoke control systems requiring Underwriters Laboratories Inc. (UL) UL555S ratings up to 350 F. It is equipped with single pole, single throw (SPST) position-indicating switches at 7 and 85-degree strokes. An integral spring return guarantees a consistent level of return torque.

The Honeywell Direct Coupled Spring Return comes with a patented design that eliminates the need for limit switches, thereby reducing power consumption. It's available in models suitable for 24, 120, and 230 VAC, and it can sustain a 95-degree angle of rotation. This device maintains its rated torque even at reduced power levels.

Additional technical specifications include a fifteen-second spring return timing, the absence of audible noise during holding, and no requirement for special cycling during long-term holding. Its operating conditions range from 0 F to 130 F (-18C to 55C), and it's fabricated with an aluminum housing for durability. Its electrical connections are facilitated by color-coded leads, simplifying the installation and maintenance processes.
