Description
Series 90 Modutrol IV motors are non-spring return modulating proportional control motors designed for use with controllers that provide a Series 90 output, enabling the operation of dampers or valves.
Features
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 standard-screw 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 form 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.
Field addable interface modules can be mounted in the junction box to upgrade the motor to Series 70 (electronic) control.
