Ternary Actuators

Ternary is the all-in-one linear actuator system from Wittenstein that merges mechanics with intelligence, integrating several separate components:

  • Electronics
  • Power, control, and Fieldbus all-in-one
  • Mechatronics
  • Stepper or Brushless Servo motor with Encoder Feedback
  • Mechanics
  • High Quality Planetary gearhead or
  • Ballscrew driven Cylinder or
  • Ballscrew driven Slide

The ternary provides easy control of position, velocity, acceleration and force, and provides for mid-move velocity changes. Precise control of multiple points eliminates the need for mechanical stops and limit switches.

The actuator uses a brushless servo motor to create its high power and dynamics. This motor turns a precision ballscrew that delivers its force to a stainless steel output rod. The components are controlled via an onboard motion controller that features PLC functionality including loops, trapezoidal motion profiles, and force limits.

Rotary Ternary, Linear Ternary

Features
  • All-in-one design eliminates the need for a separate electronics enclosure, saving cabinet space
  • Ternary offers more flexibility, controllability and precision than a pneumatic system, with no need for piping, valving, air/oil supply, filters, etc.
  • Provides easily programmable motion – position, velocity, acceleration/deceleration
  • PC-based set-up software provides for quick and easy setup
  • Standard length connectorized cables make installation fast and easy
  • Ternary has internal monitoring and alarm capabilities
  • Maintenance Free System
  • High Protection Class:        
    · IP 65 rated (LP050 is IP64)
    · Reduces integration time and cost for protection (Shrouding, Bellows, etc.)
    · Washdown capablility
  • Variety of Control Interface possibilities
  • Low Voltage Power Requirements
  • ProTern Commissioning Software

What’s New?

Analog Position Control – Ideal for applications like valve actuation to allow control from third party devices involved in process control.  Also allows for flexible position controlling without the addition of complex Fieldbus control.

Ethernet IP – All the flexibility of Devicenet while eliminating costly Network mapping software and Scanner Cards, the Ternary Ethernet IP interface offers 10/100 MB communication for point to point motion of our position controller.  For those already familiar with our Devicenet Command protocol, nothing has changed so you can even have portability of programs between EthernetIP and Devicenet Applications.
