The M9220-xxx-3 actuators are direct-mount, spring-return electric actuators that operate with these available power options:
- AC 24 V at 50/60 Hz or DC 24 V(AGx, BGx, GGx, HGx)
- AC 120 V at 60 Hz (BAx)
- AC 230 V at 50/60 Hz (BDx)
These bidirectional actuators do not require a damper linkage, and are easily installed on dampers with 1/2 in. to 3/4 in. or 12 mm to 19 mm round shafts, or 3/8 in. and 1/2 in. or 10 mm, 12 mm, and 14 mm square shafts using the standard shaft clamp included with the actuator. An optional M9220-600 Jackshaft Coupler Kit is available for 3/4 in. to 1-1/16 in. or 19 mm to 27 mm round shafts, or 5/8 in. and 3/4 in. or 16 mm, 18 mm, and 19 mm square shafts.
A single M9220-xxx-3 Electric Spring-Return Actuator provides a running and spring-return torque of 177 lb·in (20 N·m). Two or three models mounted in tandem deliver twice or triple the torque. Integral line voltage auxiliary switches are available on the -xxC models to indicate end-stop position or to perform switching functions within the selected rotation range.
