AutoLog® Wireless I/O & -Sensor Network (868 MHz)

AutoLog® WSN-868 Wireless Sensor Network products are especially designed for taking measurements from remote industrial sites and objects. It uses 868 MHz EU license-free radio band. Compact and cost effective solution for monitoring and controlling premises even without mains power.

Flexible architecture allows to create multi-purposed tree-shaped networks with centralized control. Standard Modbus RTU interface can be used to connect WSN-868 network directly to almost any device / HMI / SCADA.


  • Based on well proven AutoLog embedded technology, designed, manufactured and tested in Finland.
  • Complete solution directly from hardware manufacturer and software project designer.
  • Reliable solution based on almost 40 years experience and 20.000+ supplied RTU controllers and solutions
  • Uses Frequency Band: 868 MHz, License-free sub-band.
  • Wide operating range -40°...+85°C.
  • Advanced and modern turnkey SCADA solutions. (Traditional-, Web- and IoT Cloud SCADA systems)
  • Turnkey SCADA project can be made and maintained by FF-Automation.
  • Compact and economically priced solution with many I/O, sensor and powering variants.
  • Modbus RTU connection to WSN-868 master module
