LonWorks® to fibre optic link, point-to-point applications The LRW-102PP is a fibre optic modem designed for point-topoint fibre opticconnections between LonWorks® networks.

The LRW-102PP offers an easy way to extend the distance between LonWorks® 78 kbit/s TP/FT network segments using a fibre optic link. The LRW-102PP is designed for harsh industrial usage as well as road or railway installations meeting industrial level EMC specifications and having a wide operating temperature range. The unit also has a re-timing function that eliminates the problem of jitter andhence ensures reliable communications in all situations.

The units are well prepared for use in harsh industrial environments. Total galvanic isolation and transient protection are standard for all interfaces. The line interfaces are also equipped with extensive protection against over-currents and voltage suppression. The DIN mounted case of the unit makes it easy to mount. The surrounding air temperature can be between –40 to 70°C. To allow for uninterrupted communication the units are designed with redundant power inputs that can be powered from two separate supplies and handle an operating voltage range of 10 – 60 VDC.
