RCS has provided automation solutions to all of these markets over the years and we continually seek new markets, customers and applications. The product offering includes two basic types of actuators: electric rotary and spring return electric rotary. Construction is as follows:
Available voltages are as follows:
115 VAC, 1 phase, 50/60 Hz.
230 VAC, 1 phase, 50/60 Hz.
220/440 VAC, 3 phase, 60 Hz.
24 VDC
12 VDC
24 VAC
Application Flexibility
The RCS product line offers the broadest range of speeds and available voltages of any competing manufacturer. Coupled with an extensive line of control and communication accessories, these actuators offer both standard and unique solutions to a host of automation requirements. Standard operation for MAR and DCR models is part turn, reversible with unidirectional and multi-turn options available.
Electric Motors
All RCS electric actuators are powered by an extended duty, high-torque, reversible motor. These motors are suitable for both on/off and modulating applications, with many models rated for 100% duty. Each motor is Class "B" insulated and has an internal thermal overload protective device. This device protects the motor if a "stall" condition occurs thus preventing the motor from overheating which results in premature motor failure.
Manual Override
MAR/DCR10, 50 and 90 models feature a declutchable manual override. The actuator’s gearing is disengaged from the motor thus the actuator cannot be operated electrically while in manual operation. MAR100 through 4000 feature a manual override with an automatic electrical safety lockout switch. When the handwheel is engaged, the electrical switch isolates the motor from the supply voltage to prevent electrical operation.
