Description
The Honeywell Q181A1007 Auxiliary Potentiometer is used for Series 90 Modutrol motors. This potentiometer gives variable resistance output about the shaft position of the motor used in HVAC systems. It operates by translating the rotational movement of the shaft of the motor into the respective electrical signal. This signal can be used for remote position indication, sequencing control of other parts, or as feedback in control loops for dampers, valves, and other HVAC equipment such as air handling units and terminal units. Advantages include increased accuracy of control, increased system efficiency due to precise positioning, and compatibility with other higher levels of control.
