Honeywell Direct Coupled Actuator, 175 lb-in - MS8120W1205/U

The product being described is a Honeywell Direct Coupled Actuator with a torque capacity of 175 lb-in. This actuator features a spring return mechanism and is designed to operate under a voltage of 24 VAC, with a VA rating of 40. It operates in a two-position manner, controlled by a single-pole, single-throw (SPST) switch.

The device boasts a self-centering shaft adapter, providing a versatile coupling mechanism tailored for a wide range of shaft sizes. Certain models come equipped with the Sylk protocol for enhanced connectivity. Users can simplify connections by utilizing the device's access cover. The robust metal housing, reinforced with built-in mechanical end limits, ensures durability.

The spring return direction is field-selectable, and a shaft position indicator and scale are conveniently featured, giving clear visibility of operation. Manual winding capability with a locking function increases the usability and reliability. The actuator is UL (cUL) listed, establishing its safety and reliability. Further demonstrating its safety considerations, all versions of this model are plenum-rated per UL2043. It can come with a 3 feet 18 AWG color-coded cable for simplified installation.

Regarding its technical specifications, the actuator is designed to consume power in the range of 24 VAC. It is engineered to function efficiently in diverse temperature conditions, ranging from -40 F to 150 F (-40 C to 65 C). Its electrical connections involve field wiring ranging from 14-22 AWG to screw terminals, located beneath the removable access cover. Designed to be more than just an actuator, this model includes two SPDT auxiliary switches. Lastly, the housing mechanism incorporates a self-centering shaft adapter for enhanced stability in operation.
