Honeywell Direct Coupled 30 in-lb. Spring Return - MS8104F1210/U

The Direct Coupled 30 in-lb. Spring Return is a versatile controller designed for a variety of industrial operations. Operating on 24 VAC and having a 16 VA rating, it offers two positions and is equipped with a Single Pole Single Throw (SPST) switch. Robust and adaptable, it allows reversible mounting, supporting both clockwise and counterclockwise spring rotations. Its compact housing design also enables flush mounting to the damper.

One of the product's key features is its reliable performance, even in stringent smoke control systems requiring UL555S ratings from Underwriters Laboratories Inc, up to 350 F. It also includes models that have SPST position-indicating switches with a 7° to 85° stroke. An integral spring return ensures a consistent level of return torque, coupled with a fifteen-second spring return timing.

The device is meticulously designed to not require special cycling during prolonged holding; it operates without producing audible noise. Its patent-pending design circumvents the need for limit switches, contributing to a significant reduction in power consumption. The controller is available in models suited for 24, 120, and 230 VAC.

The Direct Coupled 30 in-lb. Spring Return demonstrates operational flexibility, with a considerable ninety-five-degree angle of rotation. Even at a reduced power level, the actuator can hold the rated torque.

The controller is also marked by its low power consumption of 16 VA. It functions optimally under a broad spectrum of operating conditions, from 0 F to 130 F (-18 C to 55 C). The electrical connections are facilitated by color-coded leads, and the sturdy aluminum housing ensures durability. This device is also equipped with two auxiliary switches for added functionality.
