Specification of Modutrol
Modutrol is shaped spring engine spare parts motors used to control dampers and valves.
• models M62xx three-wire floating control motors for use with controllers that provide SPDT switch or floating output and has a feedback potentiometer electrically isolated internally which gives an indication of the position of the motor shaft.
• models M72xx receive current or voltage signal from an electronic controller for the motor shaft position for each point between open and closed.
• M91xx and M94xx models use 135Ohm modulation signal proportional to the motor shaft position for each point between open and closed.
Modutrol motors used for dampers and control valves in industrial burner application and installation of air handling.
