Fibre optic repeater for TP/FT-10 LRW-102 LonWorks® to fibre optic link, multidrop and redundant ring applications The LRW-102 is a fibre optic modem designed for multidrop and redundant ring applications. It acts as a repeater between the two fibre optic links and as a converter between LonWorks® networks and fibre optic link. The LRW-102 offers an easy way to extend the distance between LonWorks® 78 kbit/s TP/FT network segments using a fibre optic link. The LRW-102 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. Because of the repeater functionality it eliminates the problem of jitter and hence ensures reliable communications in all situations. Configuration Easy to configure with DIP-switches. Harsh industrial environment 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 60°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. Approvals The construction of the units has gone through extensive testing and approvals both by Westermo and accredited test houses. The LRW-102 has approvals for industrial as well as railway use.
