Interfaces Meet the Innovation Pentathlete: An Interface with a Five–Fold Edge

Author / Editor: Klaus Ebinger* / Dr. Jörg Kempf

New interface device platform provides a five-fold innovation leap in five disciplines: compactness, speed, accuracy, safety and globality — Proven technology has advantages and disadvantages: Although it may be well-established and fully mature, at some point it cannot be developed any further. If additional performance is required, the only solution is a consistent innovation using the latest technology and providing customers with security for the next decade. Turck is meeting these requirements with its new IMX interface series, which has been premiered at this year’s Achema.

With more compact housing dimensions, more accurate and faster devices, SIL2 certification and several international Ex approvals for worldwide use, Turck is raising the standard for interface technology to a new level.

A look at the development of interface technology will show that manufacturers and customers increasingly have three key requirements: Safety, particularly with regard to Ex separation and functional safety (SIL), the space requirement on the DIN rail, as well as performance — particularly with regard to the speed and accuracy of the devices. Although existing interface devices can meet these requirements to a certain extent, the possibility of their further development is normally limited.

For many years, Turck has offered a wide range of interface devices on the market which have also been continually adapted to the latest developments. However, it is only with a completely new electronic platform that a manufacturer can offer future-proof innovations based on state-of-the-art technology, which can provide customers with investment security for the next decade. Turck has therefore invested a great deal of time and money in the development of a completely new generation of interface technology.

Having rigorously tested the IMX series and having acquired an extensive range of approvals for it, the automation specialist has launched the first devices of the new IMX interface platform at Achema 2015. This not only sets new standards in terms of the traditional issues of safety, space and performance already mentioned, but also opens up new markets, such as in mobile equipment, thanks to its 10...30 VDC capability.

Functional Safety

The issue of functional safety has grown in importance in recent years. In the beginning, safety integrity levels (SIL) had been equated with quality. However, plant operators have gradually developed a greater understanding of safety in their applications. Manufacturers have consequently had to meet these resulting challenges.

Turck directed its development process for the new IMX series completely in compliance with the requirements of IEC 61508. Recognized independent bodies have certified this process. The comprehensive manuals and commissioning guides support customers in the operation of the devices in functional safety circuits.
