Honeywell Direct Coupled 175 in-lb. Spring Return - MS4120F1204/U

The Direct Coupled 175 in-lb. Spring Return from Honeywell presents a robust and reliable control module suited for demanding industrial applications. This unit operates at a power rating of 120 VAC and 42 VA with a two-position single pole single throw (SPST) setup. Its reversible mounting design enables operation in either clockwise or counterclockwise spring rotation.

The sleek housing construction facilitates flush mounting to a damper, ensuring seamless integration into your existing setup. It is purposely designed to offer reliable operation in smoke control systems demanding Underwriters Laboratories Inc. UL555S ratings of up to 350 F.

This model benefits from an integral spring return that guarantees a constant level of return torque. It showcases a streamlined 15-second spring return timing and does not require special cycling during long-term holding. Further, it operates silently during the holding process.

Honeywell's unique and patent-pending design removes the need for limit switches, thus significantly reducing power consumption. It offers the flexibility of being compatible with 24, 120, and 230 VAC power sources. The actuator guarantees a sweeping ninety-five-degree angle of rotation and maintains its rated torque even at reduced power levels.

The durable and lightweight aluminum housing shelters sophisticated technical specifications. This includes a power consumption of 42 VA, and operating conditions ranging from -40 F to 130 F (-40 C to 55 C). The unit comes with a Teflon-jacketed cable for ease of electrical connection and harbors two internal auxiliary switches. The module is rated NEMA 2, indicating it is built for indoor usage with moderate protection against dust, as well as drops of water. Offering an operating temperature range of -40 F to 140 F, the Direct Coupled 175 in-lb. Spring Return pairs adaptability and strength in one advanced piece of automation technology.
