IO-Link IP20 and IP67 power supply units

With condition monitoring

Heartbeat® function: Continuous monitoring of wear factorsPower supply units
Power supply units are a key factor in the reliable operation of machines and systems. The new Heartbeat® power supply units help the user by providing continuous monitoring and displaying the load and stress levels. The load level shows the output load capacity. If the load increases, this may indicate a problem in the system – for example, where an engine requires too much power to move a corroded bearing. With their lifetime display, the power supply units also provide information about the remaining useful life of the device. Unexpected downtimes and production interruptions are now a thing of the past.

What does IO-Link do?

The IO-Link interface enables all important parameters to be read out and transferred to the control system. These can be assessed in the superordinate diagnostics system. This guarantees continuous diagnostics at a central location.
The IO-Link connection is established via the tried and tested M12 connector or spring-loaded terminals.


  • Information from the Heartbeat® power supply unit transferred via IO-Link
  • Process data, e.g. output voltage, output current
  • Heartbeat® parameters
  • Alarm messages, e.g. overload, overtemperature
  • Diagnostics information, e.g. input voltage, current stress level, service life

Balluff IO-Link power supply units are available with the IP20 and IP67 rating.

IO-Link IP20 power supply units: Energy-saving

The new versions with IP20 rating are ideal for providing a reliable and efficient voltage supply. Due to their extremely high efficiency, these power supply units save energy. This keeps loss of performance to a minimum and significantly reduces the size of the power supply unit housing. For example, the 20-A version is over 50% narrower than a conventional power supply unit. This saves space in the control cabinet.

An expansion with the optionally available IO-Link adapter saves even more energy and, therefore, money. This is because the output voltage can be switched on and off via the IO-Link as soon as part of the system is not needed, thus allowing energy saving concepts to be effectively implemented.

IO-Link IP67 power supply units for local installation without a control cabinet

Balluff power supply units with IP67 protection class are ideally suited to local installation without a control cabinet. This is because they can be used directly in the field and in harsh conditions. IO-Link enables power supply units to be installed even in locations which are difficult to access. With IO-Link, monitoring is carried out conveniently from the control room.

IO-Link IP67 power supply units cope with harsh environments extremely well.

IO-Link IP67 power supply units cope with harsh environments extremely well. IO-Link ensures monitoring in the control system so that power supply units can be installed in inaccessible locations.
