Honeywell Series 71, 72, and 76 Modutrol IV™ Motors Model HONEYWELL M7284A1004 MODUTROL IV MOTOR NON-SPRING RETURN (120V, 50/60HZ) TIME(SEC) 30-60, STROKE (DEG) ADJ. 90 M7284C1000 HONEYWELL M7284Q1009 MODUTROL IV MOTOR NON-SPRING RETURN (120V, 50/60HZ) TIME(SEC) 30-60, STROKE (DEG) ADJ. 90 M7284C1000 Dated : 23-9-2021 APPLICATION The Series 71, 72 and 76 Modutrol IV Motors are spring return and non-spring return motors used to control dampers and valves. The motors accept a current or voltage signal from an electronic controller to position a damper or valve at any point between open and closed. FEATURES • Replaces M734H,J,; M744S,T,Y; and M745L,S,T,Y Motors. • M7164, M7261, M7284, and M7294 are non-spring return motors; M7282, M7285, M7286 and M7685 are spring return motors. • Integral spring return returns motor to normal position when power is interrupted. • 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 are standard—screw terminal adapter is available. • Adapter bracket for matching shaft height of older motors is available. • Most motors have field adjustable stroke (90° to 160°). • Die-cast aluminum housing. • Integral auxiliary switches are available factory mounted, or can be field added. • Nominal timing standard of 30 seconds (90° stroke), and 60 seconds (160° stroke). Other timings available. • Spring return motors can operate valve linkages from power end or auxiliary end shafts for normally closed or normally open valve applications. • All models have dual shafts (slotted and tapped on both ends). • All models have auxiliary switch cams. • Fixed torque throughout the entire voltage range. • Motors are designed for either normally open or normally closed valves and dampers. • Models available with adjustable start (zero) and span. • Models available with 4 to 20 mA input signal. • Models available with 2 to 10 Vdc input signal.
