LW218: Optical Fibre (Receive-) Module for SSI-Signals

The optical fiber module LW218 is the receiving module of the transmission system for the optical transmission of industrial signal data via an optical fiber. The LW receiver converts the optical signals transmitted from the transmitter module to the receiver via a fiber optic line up to 2000 meters in length back into the original SSI format. The output absolute SSI data thus corresponds to the signal or absolute value originally applied at the input of the transmitter module. The conversion time from the input (transmitter) to the output (receiver) is less than 300 ns.


  • 1 SSI input / output channel [RS422] with format DATA+, DATA-, CLOCK+, CLOCK-
  • 1 open-drain-output (LW218)
  • Maximum input frequency 1 MHz
  • Very short conversion time < 300 ns
  • Optical wavelength 1300 nm
  • Transmission distance up to 2000 meter
  • Power supply 5 VDC (for LW218)
  • Power supply 10 ... 30 VDC (for LW218-1)
  • Free adjustable SSI resolution from 1 ... 99 bit
  • Snap on housing for top hat rail
    (according to EN 60715)
  • Glass fibre cables are available ready assembled
