These models deliver a minimum of 50 inlb. or 5.6 Nm. torque at rated voltage and are designed for applications where a fast response is required, typically when fume hoods are involved in the controlled space. The actuator motor is equipped with auto stroking, zero, and span features. Auto stroking means that the maximum stroke of the actuator may be field limited to anywhere between 45° and 90° while still maintaining a full throttling range of 2 VDC to 10 VDC. The zero and span features may also be field set to adjust the control response of the motor to a portion of the 2 VDC to 10 VDC input signal. These features enable the sequence of several motors off the same input signal. Refer to the actuator specifications for more information.
