Spider enables connecting four 1-Wire probes (temperature, humidity) or contacts to the RS-485 bus. Up to six Spiders (24 sensors) can be connected to a single Poseidon 2250.

Spider simplifies large-scale installations. RS-485 uses CAT5 cabling with RJ45 jacks and achieves the longest distances. Typical applications include connecting temperature probes, humidity probes or door contacts for several refrigerators in the middle of the RS-485 bus.

Typical applications include monitoring clusters of refrigerators in a supermarket. One CAT5 cable connects a cluster of 4 freezers. Each freezer contains a 1-Wire FLAT sensor connected to the Spider. Individual clusters can be daisy-chained.
