Spring Return Direct Coupled Actuator

ML4135; ML8135

The ML8135 Fast-Acting, Two- Position Actuators are spring return direct coupled actuators (DCA) with an integral junction box for on/ off damper control.

FEATURES

•Integral spring return.

•-40 C to 130 F (-40 C to 54 C) operating temperature range.

•No audible noise during holding.

•Electronic circuitry provides efficient operation while eliminating the need for limit switches.

•Ninety-five degree angle of rotation.

•Die-cast aluminum housing. Housing design allows flush mounting to damper.

•Integral junction box with three conduit openings eliminates need for separate wiring box.

•Direct mounting to 3/8 or 1/2 in. round or square shaft.

•Not intended for smoke control systems.
