The MA-ESR is a two wire, round spring return motor actuator. The MA-ESR is normally
used on the Model ND and URD dampers. The motors can be wired in parallel off of (1)
40VA transformer. One 24V 40VA transformer can power up to (5) dampers. A built in
auxillary switch can be used to interlock various field components. The switch is rated for
24VAC only.
