EAO: New Series 84 IO-Link Touch


June 29, 2021

The freely configurable, bright and capacitive IO-Link Touch opens up numerous new HMI application possibilities for a wide range of raw industrial applications. 

With the advent of digitisation in the industrial sector, machine manufacturers can develop completely new machines and equipment. At the same time, this creates an even more intensive operating experience for the end user. However, to reap the benefits of digitisation, machine manufacturers must overcome demanding challenges, for instance in terms of system complexity or the enormous investment of time and money required to digitally transform their analogue machines. With the Series 84 IO-Link Touch, digital machine systems can be equipped and operated with HMIs easily and rapidly.

Application-specific HMI variants. 

With its three HMI variants – standard, stainless steel and hygiene – the IO-Link Touch range offers actuators and indicators which are ideal for a wide range of applications in the mechanical engineering industry and far beyond.

Typical applications

  •    –   Automated production (smart factories)
  •    –   Controls and switch cabinets
  •    –   Food and beverage industry
  •    –   Packaging equipment
  •    –   Autonomous robot transport systems
  •    –   Monitoring stations for industrial conveyor belts
  •    –   Mobile, medical devices
  •    –   Transmission systems for telecommunications
  •    –   Video router systems

Simply digitally networked.

Thanks to the globally established IO-Link communication interface and programmable connection options, the innovative HMIs can be networked with an advanced machine system via an integrated M12 5-pin screw connection with a mounting depth of just 25.8 mm, making your equipment Industry 4.0-compatible.

Freely configurable HMIs.

The many potential uses for the HMIs are based on a freely selectable configuration which can be precisely aligned to the respective application – from illumination, to symbols, to the switching function. For example, the illumination can switch on with a deliberate delay when actuated. Or HMI operational readiness can be signalled by green illumination which changes to yellow when actuated, and to red a few seconds later. The configuration remains stored on the HMI even with no power supplied.


  •    –   Freely configurable HMIs with IO-Link interface (Industry 4.0)
  •    –   Optionally illuminated standard or custom symbols
  •    –   Ambient light adaptive RGB LED illumination in 16 million colours
  •    –   Capacitive actuation with different actuation sensitivities
  •    –   EAO Value Added Services and worldwide availability

Innovative RGB LED illumination.

The static or flashing RGB LED illumination in up to 16 million colours is particularly bright. Thanks to the integrated ambient light level sensor, the HMI always illuminates at the right intensity in any lighting conditions – without dazzling or being too dim. This feature also optimises the HMI’s power consumption as well as LED lifetime. Four lateral illuminated windows integrated into the front frame ensure excellent visibility of the entire status display. Combined with high-contrast and optionally illuminated standard or custom symbols, the attractive design of the IO-Link Touch means it also integrates visually in any modern application setting.
