Description
The Honeywell Modutrol IV Actuator Motors rotary motors can be set to fail safe mode to Non-Spring Return (NSR) or Spring Return, Two Position.
Application:
The Series 72 Modutrol IV Motors are used to control dampers and valves. The motors accept a current or voltage signal from an electronic controller to position a damper or valve at any point between open and closed. All models have auxiliary switch cams.
The Series 41 and Series 81 Modutrol IV Motors are 2-position (line- and low- voltage, respectively) spring-return motors. They are used to operate dampers or valves in applications where it is necessary or desirable to have the controlled element return to the starting position in the event of power failure or interruption.
Series 90 Control Circuit – 135 ohm, Series 90 proportioning controller. Series 90 high or low limit controller with manual minimum position potentiometer (with a combined total resistance of up to 500 ohms) can also be used in the control circuit. These Modutrol Motors are reversing, proportional motors used to operate valves or dampers in electric (Series 90) modulating circuits.
