Digital meets analogue: integrating modern IO-Link sensors the analogue way

  • Converts IO-Link process values into two analogue signals 4...20 mA
  • Ideal for IO-Link sensors with multiple process values
  • Plug and play: no parameter setting required
  • Resistant to cleaning agents, ideal for use in hygienic areas
  • Easy installation directly on the sensor or in the connection line

Operating principle

IO-Link sensors often provide several measured values at the same time, e.g. conductivity sensors with integrated temperature measurement. To allow these sensors to be connected to existing control systems, this converter converts two digital measured values into two analogue signals (4...20 mA). Thus, the hardware of the system is already prepared for future digitisation. The converter can be used directly without parameterisation. However if required, it can also be parameterised via IO-Link, e.g. for scaling analogue values.

Hygienic

Special housing materials as well as the high protection class IP 67 / IP 69K allow, for example, the use in the food industry even with high-pressure cleaning and aggressive cleaning agents.

Operating principle:

1 x IO-Link converts to 2 x analogue output

With this compact converter, modern IO-Link sensors that provide more than just one process value can be connected to existing control systems equipped with analogue inputs only.

Multiple measured values via IO-Link

The following is a small selection of ifm sensors that output more than just a process value via IO-Link.
