Spider

Spider connects 4 dry contacts or 1-Wire bus RJ11 sensors to Poseidon 2250 and RS-485 (RJ45) bus. Spider is an active converter between RS-485 and 1-Wire bus. Spider units can be daisy chain connected.

Spider makes it easier to connect more sensors over longer distances using the RS-485 bus. Suitable for applications in rooms and larger areas.

Typical application

• Enlarging the number of inputs for connection of dry contacts for Poseidon 2250.
• Gathering values from 19” racks, RS-485 bus runs along the wall.
• Temperature monitoring in supermarket freezers, RS-485 bus runs along the wall behind the freezers.
