FEATURES • Replaces M644, M944B,E,G,H,J,K,R,S and M945B,C,G,K,L,AD Motors. • Integral junction box provides NEMA 3 weather protection. • Integral spring return returns motor to normal position when power is interrupted. • 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. • 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. • Series 62 models include electrically isolated feedback potentiometer that provides shaft position indication. • Series 62 TRADELINE models have linear feedback, configurable for slaving Series 90 Motors.
