ML4125, ML4135, ML8125, ML8135

Fast-Acting, Two-Position Actuators

FOR HEATING, VENTILATION AND

AIR-CONDITIONING APPLICATIONS

PRODUCT DATA

FEATURES

• Integral spring return.

• -40 to 130°F (-40 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.

APPLICATION

The ML4125, ML4135, ML8125 and ML8135 Fast-Acting, Two-Position Actuators are spri ng return direct coupled actuators (DCA) with an integral junction box for on/off damper control. The actuator accepts an on/off signal from a single-pole, single-throw (spst) controller. Models are available with clockwis e (cw) or counterclockwise (ccw) spring return and are designed for heating, ventilation, and air-conditioning (HVAC) applications.

IMPORTANT

This actuator is not to be used in fire/smoke applications requiring UL555/555S approval.

ML4125, ML8125

• 100 lb-in. (11.3 N•m) minimum driving torque.

• 25 to 40 second drive timing (load dependant).

• Models available for 24, 120, and 230 Vac.

ML4135, ML8135

• 40 lb-in. (4.5 N•m) minimum driving torque.

• 20 to 25 second drive timing (load dependant).

• Models available for 24 and 120 Vac.

Mounting:

3/8 in. (10 mm) to 1/2 in. (13 mm) square or round damper

shafts. Actuator ca n b e m ounted with shaft in any pos iti on. Secure hub to shaft with:

ML8125, ML4125A,B: Four 1/4-28 UNF set screws. Use

1/8 in. Allen wrench to tighten set screws.

ML8135, ML4135: Two 1/4-28 UNF set screws. Use 1/8 in.

Allen wrench to tighten set screws.

ML4125C,D: Four 3 mm set screws. Use 3 mm Allen wrench

to tighten set screws.

IMPORTANT

Honeywell does not recommend using linkages with these actuators because side-loading of the output hub reduces actuator life.
