Johnson Controls M9220-HGC-3

DAMPER ACTUATOR 20 NM SR; 20 NM SR DPR ACT 0 TO 20 VDC ADJ START \& SPAN 24 VAC 50/60 HZ 2 AUX SW

The M9220-xxx-3 Actuators are direct mount, spring return electric actuators that operate on 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 ½ to ¾ in. or 12 to 19 mm round shafts, or ⅜ and ½ in. or 10, 12, and 14 mm square shafts using the standard shaft clamp included with the actuator. An optional M9220-600 Jackshaft Coupler Kit is available for ¾ to 1-1/16 in. or 19 to 27 mm round shafts, or ⅝ and ¾ in. or 16, 18, 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 (354 lb·in [40 N·m] or 531 lb·in [60 N·m]). 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.
