Series 90

Modutrol IV™ Motors

APPLICATION

The Series 90 Modutrol IV™ Motors are spring return and

non-spring return modulating proportional control motors. Use

these motors with controllers that provide a Series 90 output

to operate dampers or valves.

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

models.

• 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.
