Data sheet:

Interface - Plastic fiber optic <> RS422/RS485 Industry

  • Interface fiber optics, model 61201

Also transmit industrial interfaces with noise immunity

The model 61201 Interface transmits serial RS422 or RS485 data via plastic duplex fibers over a distance of up to 100 meters. The external supply voltage ensures stable conditions for reliable operation of the often low-impedance terminated differential interfaces.

Properties

Interfaces:

  • Selectable RS422 / RS485 interface
    • 9-pin Sub-D plug
  • Fiber optics interface
    • Direct connection of the fiber optic cable without a connector
    • Alternate names: POF (polymer optical fiber, plastic optical fiber)

Management and connectivity:

  • The interface is very easy to install:
    • Cut the fiber-optic cable with a sharp knife at right angles.
    • Insert into patented adapter of the W&T interface.
    • Plug the adapter into the PC.
    • That’s it!
  • No re-configuration of transmission parameters required
  • 100% protection against interfering radiation
  • Electrical isolation
  • Lightning protection

Power supply:

  • External
    • 12V-24V AC/DC via plug-in screw terminal
    • Galvanically isolated power connection

Standards & more

  • Conforms to standards both in office and industrial environments:
    • High noise resistance for industrial environments
    • Low noise emission for residential and business areas
  • 5 year guarantee
