The Hays Cleveland F-09160-A0 Linear Actuator with Analog Input Circuitry are compact, versatile drives that can be used to position final control elements in either open or closed-loop combustion and process control applications. They accept a 4-20 mA dc or 1-5 V dc control signal to position a final control element such as a damper, control valve, louver, stoker lever, variable speed transmission, or similar device, over a six-inch range of travel. These rugged actuators feature a stepper motor for instantaneous stops and starts (without coasting) in response to switched line voltage input. High starting torque overcomes static friction and overload stalling will not damage the impedance-protected motor. Several standard thrust/stroke time ranges are available, as well as convenient options such as weather-resistant housing, hand wheel, adjustable “safe start” position switch, isolated auxiliary end switch, secondary auxiliary switch for retracted arm position and externally or internally generated feedback position signal.
