Is product protocol not complying with your standards and you simply want to change it? Do you want to alter its atributes or functions? Too much of something or is something missing? We`re flexible. We`ll adjust our products to your needs.

GATEWAYS

1-WIRE SOLUTION

  • Cabling is simple, it is three-wire connection with up to twenty sensors on one line with lenght max. 300 metres, its based on buses.
  • Sensors send number values only. Data are transmitted with data communication. Thanks to checksum any mistakes are excluded.
  • Digital sensors are cheap and precise comparing to analog ones (PT1000, PT100).
  • Temperature measurement is in the range of -40 C and 125 C.
  • We recommend to use our accessories only (sensors, terminal PCBs, hubs) in order to protect line against overvoltage, short circuit and nuisances, and also because of problem-free and convenient installation.
