20mA <> POF interface for Siemens S5

  • FOC <> 20mA interface for Siemens S5

PC/PLC connection via fiber-optic cable


General information

  • Conversion from 20mA to FO cable
  • Plug compatible with Siemens S5
  • Easier installed than any copper cable, thanks to patented FOC adapter
  • The interface is very easy to install:
    • Cut the fiber-optic cable with a sharp knife at right angles.
    • Insert end into the patented adapter of the W&T interface.
    • Plug into control system.
    • That’s it!
  • 100% protection against interfering radiation
  • No setting of the transmission parameters necessary
  • Conforms to standards both in office and industrial environments:
    • High noise resistance per EN 61000-6-2
    • Low noise emission per EN 55032:2015 + A1 Cl. B, EN 61000-3-2 & EN 61000-3-3

Background information:

Every electrical device generates electromagnetic waves, be it directly (e.g. mobile phone, radio, TV) or as a "by-product". Most affected are thereby other electronic devices, which can be severely disrupted by such radiation, even if they themselves generate electromagnetic waves. This whole issue is referred to as electromagnetic compatibility. Fiber-optic cables do not transmit or generate electromagnetic waves. They also electrically isolate the connected devices.
