Honeywell electric zone damper with a 12" diameter, a 24 volt ML6161A1000 motor, and a ML6161A2009 direct coupled actuator. This zone damper features 90-second timing and a SPDT floating input signal. DM7600 zone dampers are intended to be used in commercial zoning systems as an individual zone damper controlled by a zone thermostat, and as a bypass damper controlled by a duct static pressure sensor/controller.
