PRODUCT DATA

FEATURES

• Directly replaces M934A,D, M941, M944A,C,D, M945A,D,F, M954, M965, and M975 motors.

• Oil-immersed motor and gear train for reliable performance and long life.

• Integral junction box provides NEMA 3 weather protection.

• Motor and circuitry operate from 24 Vac. Models available with factory installed transformer, or a field-added internal transformer.

• Quick-connect terminals standard—screw terminal adapter available.

• Adapter bracket for matching shaft height of older motors standard with TRADELINE motors.

• Field adjustable stroke (90° to 160°) models available.

• Nominal timing of 30 seconds for 90° stroke and 60 seconds for 160° stroke standard. Other timings available.

• Die-cast aluminum housing.

• Integral auxiliary switches available factory mounted, or can be field added to TRADELINE

• Integral spring returns motor shaft to normal position (fully open or fully closed, depending on model) upon power interruption.

• Field addable interface modules can be mounted in the junction box to upgrade the motor to Series 70 (electronic) control.

• TRADELINE spring return motors can operate valve linkages from power end or auxiliary end shafts for normally closed or normally open valve applications.

Electrically normally closed. Shaft rotates clockwise (as viewed from the power end) with control signal increase. Motor drives to normally closed position when powered with control wiring not connected.

Electrically normally open. Shaft rotates counterclockwise (as viewed from the power end) with control signal increase. Motor drives to normally open position when powered with control wiring not connected.

Models available special order only. Contact your Honeywell Sales Representative.

NOTE: Torque designation corresponds to torque rating at standard timing (nominally 60 sec for 160° and 30 sec for 90° except

for 300 lb-in. motors which have timings of 2 or 4 min).
