  • The optical fibre modules LW217 & LW218 are forming together a transmission system for data transmission of SSI signals by means of optical fibres. 
  • Safe and reliably transmission of signals, up to a distance of 1500m 
  • The optical fibre cable can be routed through explosive areas as well
  • Resistant agaisnt extremely strong electromagnetic fields
  • For use with all encoders and sensors equipped Synchronous Serial Interface (SSI)
  • Adjustaable maximum SSI resolution of 13 bit or 25 bit
  • Maximum clock frequency 500 kHz
  • Power supply either 5VDC or 10-30 VDC
  • Compact DIN rail mounting
  • Glass fibre cables are available ready assembled
