  • Converter operating conditions: –30 to +70°C (-22 to +160°F), relative humidity max. 85%
  • Environment: Indoor or outdoor use – IP65, wall mount
  • External probe: External Pt100 sensor for sub-zero temperatures (stainless steel housing, 2m cable)
  • Interface: RS-485, terminals
  • Compatible with: Poseidon2 4002
  • Power supply: From the Poseidon (12V), or 10..35VDC
Applications and usage: 
  • Temperature monitoring in pharmaceutical or freezing works.
  • Accurate temperature monitoring in food processing
  • Temeprature monitoring in civil engineering and industrial ovens
