Honeywell Direct Coupled 80 in-lb. Spring Return - MS8109F1210/U

The Honeywell Direct Coupled 80 in-lb. Spring Return controller is a robust piece of equipment best suited for industrial automation tasks. This controller utilizes 24 VAC with a 23 VA power consumption rating, and adheres to a standard single pole, single throw (SPST) two-position model. A key feature of this controller is its reversible mounting ability, simplifying the installation process by accommodating both clockwise and counterclockwise spring rotations. The design further allows for flush mounting to dampers and it operates reliably within smoke control systems requiring UL555S ratings up to 350°F.

This controller is available with a SPST position-indicating switch, allowing for 7 degree and 85 degree stroke operation. An integrated spring return ensures a steady level of return torque and a quick, fifteen-second spring return timing makes it a reliable choice for swift applications.

Notably, there's no need for frequent cycling during extensive hold periods, and the controller guarantees silent operation during holding times. Its revolutionary patent-pending design eliminates the need for limit switches, thus reducing overall power consumption. Models can function reliably with 24, 120, and 230 VAC, offering a 95-degree angle of rotation, and the actuator maintains rated torque at reduced power levels.

In terms of technical specifications, it showcases resilience with operating conditions ranging from 0°F to 130°F (-18°C to 55°C). Electrical connections are easily manageable thanks to color-coded leads, while the aluminum housing contributes to robustness. The device also comes equipped with two auxiliary switches, adding to the convenience and functionality of this superior Honeywell product.
