General

The Series 61 and Series 62 Modutrol IVô Motors are three-wire spring return and non-spring return floating control motors. Use these motors with controllers that provide a switched spdt or floating output to operate dampers or valves.

The Series 62 motors have an internal electrically isolated feedback potentiometer that provides indication of the motor shaft position and can be used for slaving Series 90 Motors or rebalancing an external control circuit.

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 standardóscrew 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.
