Honeywell Direct Coupled 175 in-lb. Spring Return - MS4120F1006/U

The Direct Coupled 175 in-lb. Spring Return is a robust Honeywell device with a power rating of 120 VAC and 42 VA. The design supports two positions with Single Pole Single Throw (SPST) switch arrangement. Exceptionally versatile, it accommodates clockwise or counterclockwise spring rotation due to its reversible mounting feature. The housing design encourages flush mounting to a damper for a neat installation.

Built to ensure reliability, it can operate efficiently in a smoke control system that necessitates Underwriters Laboratories Inc. UL555S ratings as high as 350 degrees Fahrenheit. Several models are equipped with SPST position-indicating switches employing 7- or 85-degree stroke. Its integrated spring return guarantees a consistent level of return torque, and a fifteen-second spring return timing feature amplifies performance efficiency.

The Direct Coupled 175 in-lb. Spring Return does not require special cycling during prolonged holding periods, nor does it produce any audible noise. Its patent-pending design forgoes the need for limit switches, reducing power consumption significantly. Additionally, the product comes in models suitable for 24, 120, and 230 VAC power supplies.

The actuator flaunts a ninety-five-degree angle of rotation, holding the rated torque even at minimal power levels. Its durable Teflon-jacketed cable ensures a reliable electrical connection under extreme temperatures. Encased in an aluminum housing, the device comes with a spring return fail-safe mode.

This controller can comfortably operate within an expansive temperature range from -40°F to 140°F, making it resilient under harsh conditions. Adhering to the NEMA 2 standards, the Direct Coupled 175 in-lb. Spring Return is a remarkable addition to Honeywell's automated control system offerings.
