Honeywell Direct Coupled 30 in-lb. Spring Return - MS4604F1210/U

The Honeywell Direct Coupled 30 in-lb. Spring Return is a robust and energy-efficient control system designed for dependable operation in a variety of industrial settings. Powered by 230 VAC, this device boasts a low power consumption rating of just 29.9 VA. It utilizes an SPST, two-position control system that works seamlessly in smoke control environments requiring UL555S ratings up to 350°F.

This controller offers the convenience of reversible mounting, accommodating either clockwise (CW) or counterclockwise (CCW) spring rotation, and the minimalistic housing design allows for flush mounting to the damper. Its integral spring return mechanism ensures consistent return torque, with a swift spring return timing of 15 seconds.

Standout features of this controller include models with SPST position-indicating switches that can perform at 7-degree and 85-degree strokes, and a patent-pending design that eradicates the need for limit switches, thereby reducing power consumption. This model is versatile, produced for varying voltage requirements- 24, 120, and 230 VAC.

With an impressive 95-degree angle of rotation, the actuator maintains its rated torque even at reduced power levels. Long-lasting holding performance is facilitated without requiring any specific cycling procedure and minus any audible disturbance.

In terms of technical specifications, this device operates effectively in conditions ranging from 0°F to 130°F (-18°C to 55°C). It employs color-coded leads for easy electrical connection, and its housing is composed of durable aluminum. Additionally, it includes a pair of auxiliary switches.
