JOHNSON CONTROLS M9220-BGC-3 Spring Return Damper Actuator.
Features:
Simple direct coupling reduces installation and commissioning time while improving reliability by eliminating damper linkages
Reversible mounting design enables the actuator to spring return in either direction
Robust 177 lb-in (20 Nm) torque rating
30 to 90° adjustable stroke CW or CCW with optional M9220-603 adjustable stop kit, mechanically limited 95°
Fits 1/2 to 3/4 (12 to 19 mm) round or 3/8 to 1/2 (10 to 14mm) square shafts.
Fits 3/4 to 1-1/16 (19 to 27 mm) or 5/8 to 3/4 (16 to 19 mm) square shafts with optional M9220-600 jackshaft adapter
Auto calibration feature adapts the actuator to the damper stroke
On-Off, floating and DC 0(2)
10 V proportional control
DC 0(4) ... 20 mA proportional control w/optional 500 Ohm resistor
HGx proportional models have adjustable start and span
Removable coupler adapts to a shorter damper shaft
Electronic stall detection throughout entire rotation range extends the life of the actuator by deactivating the actuator motor when an overload condition is detected
Integral 48 in. (1.2 m) halogen-free cables with colored and numbered conductors simplify field wiring
Integral auxiliary switches (xxC Models) provide one fixed and one adjustable switch point with line voltage capability
