Tritex II DC Power Solution
The Tritex II DC powered actuators offer the ideal self-contained electric actuator solution for customers needing 12-48 VDC power input. By incorporating an actuator, servo drive and position controller in one unit, the Tritex II DC actuators provide a complete motion solution!
Linear Applications
The Tritex II DC linear actuators are available in 60 and 75 mm frame sizes and offer forces to 1000 lbs continuous (4kN) and speeds to 33 in/sec (800 mm/sec). Tritex II linear actuators employ Exlar’s patented, inverted roller screw mechanism for converting rotary motion to highly robust and long-life linear motion. These characteristics enable the Tritex actuator to solve applications that previously required pneumatic or hydraulic cylinders. No additional mechanisms (such as acme or ball screws) are necessary to convert the actuator’s rotary power into linear motion in order to move the load.
Ideal for mobile and remote applications using DC power sources, the Tritex II DC actuators offer the power needed to perform real world applications. Simple to configure, yet powerful interface software allows the Tritex II actuators perform nearly any motion application. The Tritex II linear actuator can be programmed to follow an analog command signal, making it ideal for controlling valves and dampers in process control applications or adjustment mechanisms on mobile equipment.
Rotary Applications
The Tritex II DC rotary products are available in 60 and 90mm frame sizes as motor only products and with integrated planetary gearing offering ratios from 4:1 to 100:1. Tritex II rotary motors and gearmotors provide high response and precise control of a rotatable shaft similar to that found in any electric motor. The difference is that with Tritex II you can program (via your PC) the rotational speed and position of the output shaft in response to external commands. For example, the motor can be commanded to rotate at a controlled velocity and precisely stop at a preprogrammed position. You can also program the unit to run at a preset velocity until a switch input is received or a preprogrammed torque level is produced against a load. Alternatively, the rotary Tritex II actuators can be set up to follow an analog signal, either voltage or current, representing your choice of torque, velocity, or position.
Signals for initiating the preprogram-med velocity and position commands come from optically isolated inputs or directly via network communications. Likewise, isolated output commands of the status and events allow precise coordination with your system controls or machine operator.
Flexible Communications
Multiple feedback types including absolute feedback allow you to select the system that is best-suited for your application. Digital and analog I/O plus popular communication networks such as Modbus TCP, Ethernet/IP and PROFINET IO (future networks include CANopen and Hart) allow the Tritex II to become an integral part of your control architecture or machine control processes.
Optional Internal Gear Reducer
If the application requires greater torque and less speed than available with the base unit, the Tritex II is available with an integral servo grade planetary gear reducer. Gear ratios of 4:1 to 100:1 allow the power of Tritex II to be applied over a broad range of torque requirements.

Tritex II Series Operation
The Tritex II Series actuators can operate in one of five different motion-producing modes. These modes solve an endless variety of applications in industrial automation, medical equipment, fastening and joining, blow molding, injection molding, testing, food processing, and more.
Programmed functions are stored in the Tritex II non-volatile memory. A standard RS/485 serial interface allows control, programming and monitoring of all aspects of the motor or actuator as it performs your application. Optional communications protocols are available.
