In the complex and often hazardous landscape of industrial operations, ensuring maximum safety while maintaining operational efficiency is not only a goal, but a necessity. Human-machine interfaces (HMIs) are the critical link between the human operator and the sophisticated machinery used in today's industry. The VisuNet GXP and VisuNet FLX HMIs from Pepperl+Fuchs represent a significant step forward in the field of explosion-protected HMIs. Developed with precision and foresight, these series are an example of how cutting-edge technology can meet strict safety standards to protect human lives and infrastructure investments.
Explosion protection is more than compliance and safety
The inherent risks of operating in environments with explosive atmospheres - whether due to flammable gases, vapors or combustible dusts - require HMIs that do more than just meet safety standards. The VisuNet GXP and FLX series not only meet ATEX, IECEx and NEC requirements, as well as other global standards, but also offer a sleek design. Thanks to the innovative design, these HMIs ensure that there is no ignition source, providing safety for operators and safety managers alike. The integration of intrinsically safe circuits and sand-encapsulated enclosures illustrates the holistic safety approach of these series.
Slim design and flexible adaptability up to Zone 1/21 and Div. 2
Unlike the bulky and heavy designs often associated with explosion-proof devices, the VisuNet GXP and VisuNet FLX series feature a lightweight and compact form factor without compromising on safety or functionality. This design innovation not only simplifies installation and mobility, but also opens up new possibilities for system integration and customization. The adaptability of the two HMI series is also underlined by the fact that they allow for a variety of customized modifications, from mobile trolley solutions to a wide range of mounting options, ensuring that all operational requirements are met precisely.
Precision in hygiene and safety in the pharmaceutical industry
The strict regulatory environment in the pharmaceutical industry makes the development and operation of HMIs even more complex. The VisuNet GXP and VisuNet FLX series take up this challenge with features that meet the special requirements of the pharmaceutical industry: GMP-compliant design, easy cleaning and minimized risk of contamination. These HMIs feature an edgeless design and an antibacterial keypad, housed in an IP66-rated stainless steel enclosure (or alternatively aluminum) to withstand aggressive cleaning agents. The integration of VisuNet Control Center add-on software also increases operational efficiency by enabling remote management and maintenance of all HMIs, reducing the need to physically enter cleanrooms, which is often preceded by a time-consuming decontamination process. VisuNet Control Center makes it possible to install updates on all devices simultaneously from a central location. This guarantees quick and easy management of HMIs and ensures that cybersecurity standards are always up to date.
Customized solutions for demanding industries
In industries where the environment itself presents considerable challenges, the VisuNet GXP and VisuNet FLX series are characterized by their ruggedness. The new extended temperature variant of the VisuNet FLX HMI series has a marine-grade aluminum housing and can withstand even extreme temperature fluctuations from -20 to +50 °C. Together with suitable sunshields, they are therefore perfect for outdoor applications, for example in ship and truck loading and filling applications. The option of attaching additional sunshields to protect against sun, rain and environmental influences further underlines the adaptability of these HMIs to any application scenario.
Convenient maintenance thanks to modular design
The concept of modularity is at the heart of the VisuNet HMI series and not only enables flexible customization, but also simplifies maintenance. The division into three main components - the Display Unit (DPU), the Computing Unit (PC Unit or Thin Client Unit) and the Power Supply Unit (PSU) - enables parts to be replaced and upgraded quickly, even in hazardous areas. This design approach minimizes downtime and logistical issues associated with repairs and demonstrates an understanding of the operational realities of the industry working in hazardous areas.
Setting new standards for HMIs in hazardous areas
The VisuNet GXP and VisuNet FLX series from Pepperl+Fuchs are more than just HMIs; they are proof of the ability to combine safety, efficiency and flexibility in the most demanding industrial environments. By integrating advanced technologies, meeting the strictest safety standards and offering exceptional customization options, these series set new standards for what can be expected from HMIs in hazardous areas. For industries looking to improve their operational capabilities while ensuring the safety of their employees and equipment, the VisuNet series is a smart and future-proof investment.
