Short info: Universal encoder system - fiber optics

  • A modular encoder system with electronic function modules in the switchboard
  • Position and speed monitoring, optionally available with safety certification SIL 2 / PL d (only speed monitoring)
  • Interference-free FOC signal transmission via two fiber optic cables
  • Resolution: absolute 12 bit singleturn / 12 bit multiturn and incremental of 1024 ppr

Universal encoder system - fiber optics

The proven modular universal encoder systems in the first generation of U-ONE reliably determine and monitor speed and position. The LWL (FOC) encoder systems are comprised of a basic unit and function modules in the switchboard. They are ideal for applications in which signal transmission via fiber optic cable is possible and there is sufficient space in the switchboard. The encoder systems transmit signals over long distances of up to 1,000 meters with no interference using two fiber optic cables. The encoder system solutions are suitable for use both in new plants and as a modernization solution. The all-in-one encoder systems are directly mounted onto the shaft that needs to be monitored. They therefore require no additional mechanical components such as distribution gears, distribution couplings or speed increasing gears and additionally offer higher accuracy. The encoder systems are optionally available as certified for safe speed monitoring up to SIL 2 / PL d.
