IO221: Signal Converter Strain gauge >>> IO-Link

Signal converter with strain gauge input and IO-Link interface for force sensors and load cells. This IO-Link coupler transfers strain gauge signals into the IO-Link world. In addition, the conversion result can be called up via a USB port. The device parameterization is simple via the USB interface or via IO-Link using various engineering tools.

The device impresses with its compact housing for quick DIN rail snap mounting. The device is optionally available with three HTL PNP control inputs and two PNP control outputs as IO221/CO.

The IO221 belongs to the IO22x device family. Other available devices are the IO220 (with analog input), IO222 (with incremental input) and IO223 (with SSI input).


  • 1 Strain gauge input
  • 3 VDC and 10 VDC bridge voltage per sensor connection
  • 1 … 10 mV sensitivity
  • optionally 3 control inputs for PNP signals [10 ... 30 VDC]
  • IO link interface
  • Power supply 12 ... 30 VDC
  • Compact housing for mounting on 35 mm DIN rail
