The RLH series actuators provide true spring return operation for reliable fail-safe application and positive close off on air tight dampers. The spring return system provides consistent torque to the damper with, and without, power applied to the actuator. The RLH series provides 95o of rotation and is provided with a graduated position indicator showing 0o to 90o. The RLH (-S) versions are provided with 2 built-in auxiliary switches. The SPDT switches provide for safety interfacing (fan start-up) or signaling.
