Features:

Simple direct coupling reduces installation and commissioning time while improving reliability by eliminating damper linkages
Robust 70 lb-in (8 Nm) torque rating
Rotation range 0 to 90° in 5° increments, mechanically limited to 93°
Fits 3/8 to 3/4 (10 to 20 mm) round shaft, 3/8 to 5/8 (10 to 16 mm) square shaft; 1 (25.4 mm) diameter jackshaft with M9000-154 adapter
On-off, floating and proportional control inputs meet the needs of most applications
Output position feedback provides simple closed-loop control with accurate position sensing
Electronic stall detection ensures higher reliability by deactivating the actuator motor when a stall condition is detected
Jumper selectable DC 0(2).10 V or DC 0(4).20 mA, proportional control
Zero and span adjustment (HGx models)allows sequential operation of dampers from a single input signal of DC 0(2).10 V, DC 0(4).20 V or DC 0(4).20 mA
Jumper-selectable rotation direction and manual gear release simplify installation, setup, and field adjustments
2-SPDT optional auxiliary switches
1/2 NPT threaded housing provides easy connection for electrical fittings
Manual gear release simplifies damper / valve setup and commissioning
