APPLICATION
The Series 61 and Series 62 Modutrol IV™ Motors are
three-wire spring return and non-spring return floating control

switched spdt or floating output to operate dampers or valves.
The Series 62 motors also 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.
