Since 1968, RCS has been providing the most complete line of reliable Rotary and Failsafe electric actuators to the automation market.
ElectripowrTM Type MAR
85 to 48,000 Inch Pounds Torque Output
The industry's most advanced line of electric rotary actuators
MA-8 85 in. lbs. torque at 2 sec./90 deg.
|Ball, butterfly, plug and choke valves
||Dampers, power switches, safety and flow monitoring devices
||Automatic door and braking operations
||Machine and fixture indexing
||Combined with optional RCS DigilineTM products, these actuators can
perform an almost limitless range of functions, including multi-turn
applications and precision process control operations|
|Common to all RCS electric motor driven actuators
||Powered by n rugged high-torque, integral, single phase, reversible motor
||MAR-l 0 through 90 feature the unique RCS disengageable manual override.
Valve cannot be operated electrically while manual override is engaged.
||MAR-l 00 through 4000 have a disengageable handwheel with an automatic
electrical lock-out safety switch to prevent electrical operation while the
handwheel is engaged.
||Precision-cut gears and shahs of heat-treated, high alloy steel.
||Unique adjustment plates permit fast, accurate setting of travel limit
switches. Switch activating cams independently adjustable for maximum
setting flexibility and accuracy.
||Mechanical, visual output shaft position indicator standard on all models.
||Built-in motor overload protector
||Ideally suited for automated systems; 60 second speeds available for PLCs
and computer controlled systems.
||All models permanently lubricated.
||Gear train will withstand stall torque.
||Can be mounted and run in any position.
||Accessible, dearly marked integral terminal strip assures fast, easy
||Output for output the most compact and versatile actuators in the
||Electroless nickel plated output shahs provide maximum corrosion
||NEMA 4 and/or NEMA 7 enclosures-on standard models.
||2 SPDT switches.|
|Voltages: All models 220Vac,50/60 Hz, 1 phase;|

|Special shah configurations.
||Integral potentiometer 1000 Ohm, Dual 1 K Ohm, 1 K/l 5K Ohm, 2 Watts, 1%
||Auxiliary switches for other switching functions.
||Relays for two-wire control.
||Relays for momentary contact actuation.
||Heaters and thermostats.
||Special corrosion-resistant coatings.
||Manual electrical control stations with many combinations for local or
||Positioning controllers for "On/Off," floating or proportional
control. Controllers are designed to automatically proportion in relation to
a resistance, current or voltage command signal. Command signal may be
obtained from a detector or a manual command potentiometer
||Custom designs for varying requirements.
||Digi-TorkTM solid-state, adjustable, bi-directional current sensor
||Digi-SpeedTM solid state, variable ON-OFF time controls; variable speed
