HW group Spider

Spider is an active converter between RS-485 and 1-Wire bus. Connects four input sensors (dry contacts or 1-Wire bus) to Poseidon by the RS-485 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.

• Up to 4 Spider units can be connected to one Poseidon model 2250.
  • With Spider and S-Hub units it is easy to create flexible installations with up to 50 sensors.
  
  
  
• Four RJ11 inputs support these sensors:
  • Temp-1Wire (1m / 3m / 10m / Outdoor / Temp-Rack19 / HTemp-Rack19)
  • Humid-1Wire (1m / 3m / 10m / HTemp-Rack19)
  • Input for Dry Contact (Flood / smoke and gasses / voltage and current / motion and position detectors)

Application examples

• Detection of system voltage, UPS function detection, Voltage failure alarm activation, On/Off control, Device restart
• 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

Input

• 4x 1-Wire probe (temperature or humidity)
  6 values (at most 2 combined temp/humidity probes can be connected)
• 4x dry contact

Output

• RS-485 bus –RJ45 (includes power)
• Poseidon 2250 supports up to 26 probes or 4 Spider units in total
• An extra power supply adapter is required to connect two or more Spiders
• The RS-485 communication bus can be up to 1200m (4000ft) long
• The last sensor on the RS-485 bus (at the end of the line) must terminate the bus
  (“Bus Mode” jumpers set to LAST)
