The PROFIBUS OLMs comply with the standard EN 50170 /2/ and with the technical
guideline “Optical transmission technology for PROFIBUS” published by the PROFIBUS
User Organization (PNO).
OLM/G12 and OLM/G12-EEC have the same functions. They only differ in the
specification of the ambient climatic conditions: the OLM/G12 is suitable for use in the
standard temperature range from 0 °C to 60 °C, whereas the OLM/G12-EEC (extended
environmental conditions) can be used in the extended temperature range of -25 °C to
+60 °C and up to 100% humidity (condensing).
