Industrial automation

Due to the evolution in electronics, we notice that more and more areas are being automated. In the production processes, this makes more use of sensors and actuators, and this for measuring, controlling and adjusting the (production) process. Today industrial automation and industry 4.0 go hand in hand with the aim to make the processes run smarter and more efficiently. Within the Elipse product portfolio, our manufacturers are also evolving towards smarter solutions, such as the integration of a fieldbus and a sensor bus, that lead to success.

PULS: DIN rail power supply with IO-link port

The first DIN rail power supply with an integrated IO-link port


The power is placed on a central node in the system and records a significant amount of real-time information that is of particular interest to both the company and the system manufacturer. It is more than just current flow.


This data helps increase system availability and reduce maintenance and operating costs. This means that the power supply has the possibility – in parallel to its function as a converter – to also function as a sensor, thereby making an important contribution to the Industrial Internet of Things (IIoT).


The DIMENSION QT40.241-B2 ensures that PULS markets the first 3-phase DIN rail power supply (24V / 40A) that makes this system data available to users via an I / O port.

Award-winning IO-Link device – even before market launch

The Manufacturing Leadership Council of the Frost & Sullivan consultancy agency  is looking for innovations that contribute to digitalization in the production industry.


With this in mind, PULS submitted the QT40.241 B2 to the panel in the first quarter of 2018. The panel members conducted intensive tests to demonstrate the added value that the electronic power supply provides to production companies. Frost & Sullivan was very impressed with PULS ‘user-oriented strategy. The result was that the QT40.241-B2 already received the respected Manufacturing Leadership Award before the official market launch.

Extract valuable information directly from your application

Acyclical parameters

The acyclic parameters include static and dynamic device information, as well as input and output parameters that can be requested from the master at any time.

Cyclical parameters

The output current is recorded in the cyclic process data and communicated every 2 ms by the QT40.241-B2 to the IO-Link master.


Events can be warnings or error messages, such as an input voltage that is too low or too high, an overload or too high a temperature.

Remote functions 

The user can set the output voltage of the QT40.241-B2 through the configuration software and turn the device on and off remotely.

Advantages of IO-Link as a communication protocol


The component requirements for an IO-Link port in the power supply are relatively low compared to more complex communication protocols. This offers several advantages: thanks to the low number of additional components, the MTBF (Mean Time Between Failures) value of the QT40.241-B2 remains consistently high. The MTBF stands at 678,000 hours and is indicative of the reliability and fault tolerance of the device.


IO-Link is designed as a user-friendly plug-and-play solution. Installation and operation are implemented simply and inexpensively. The port can be wired with standard, unshielded IO cables. Furthermore, compatibility with all standard Fieldbus and automation systems is offered, which in turn guarantees flexible usage options.


IO-Link is very robust and offers a high level of security. Industrial power supplies are often exposed to harsh environments of the lower automation level and must also be protected from external manipulation. Data transmission via IO-Link has been field-tested for these applications.

Integration of the QT40 into an existing IO-Link system

IO-Link is designed to retrieve the signals from the sensors and actuators (IO-Link devices) of the field level. These are fed into the respective Fieldbus system via an IO-Link master and sent to the automation system.


The combination of Fieldbus and IO-Link enables continuous communication at all levels. IO-Link is an open standard that is compatible with all common Fieldbus and automation systems. This allows flexible use.


The integration of the QT40.241-B2 into an existing IO-Link system only requires a connection to the IO-Link master. Standardized, unshielded IO cables are used for this. Installation and operation are straightforward and can be implemented cost-effectively.

REX12D Electronic circuit protection with IO-Link

The REX12D series combines the benefits of the flexible and compact REX “all-in-one” solution with the features of digital and intelligent circuit protection with IO-Link connection.


The system combines 24 VDC overcurrent protection with the communication capabilities of the IO-Link system. This smart communication allows full transparency of the 24 VDC power supply and provides all the necessary information for a reliable production process at an early stage.


Up to 16 channels of the REX12D overcurrent protection can be mounted side by side as one or two-channel modules in fixed or variable powers. No additional accessories are required for the mechanical connection of the individual components.


Early notification in case of malfunctions and a quick response to current problems guarantees the continuity of the system, is cost-effective and improves the stability of the production process.


Your benefits:

  • Enhanced machine uptime because IO-Link technology provides greater transparency and remote diagnostics.
  • Ease of PLC integration through pre-programmed functional modules and libraries.
  • Minimised stock levels because only one adjustable module is required for all current values ​​from 1A to 10A.
