Remote I/O System "u-remote" is a real winner

32 conductor connections on a single I/O module. - Eight individually pluggable sensors on a system width of just 11.5 mm - shorter project times and faster maintenance and tooling. The system has also been expanded through the addition of input and output modules with individual channel diagnosis and functions for frequency-dependent system automation. "u-remote" triumphs at Hannover Messe 2014 with superior features.

Following the successful launch of "u-remote" at the end of 2013, Weidmüller is once again raising the bar in modern I/O technology with new HD modules. HD stands for high density and the abbreviation is not used without good reason: four lines with wire cross-sections of 0.14 to 0.32 mm2 can be connected to every single HD connector, producing 32 connection points on what is already the narrowest module width on the market - just 11.5 mm.

This gives the "u-remote" a connection density never achieved before and makes possible a much smaller design than that used in all alternative systems with a comparable range of functions. Connection density, of course, goes hand in hand with system structure flexibility: there is enough room on these new HD modules for all the wiring for eight individually pluggable sensors or actuators. On all other systems currently available, these would have to be distributed over several modules.

And this is the very area in which Weidmüller is developing the superior handling concept of "u-remote". The resulting plug & play solution for the HD connectors is very simple but embodies very sophisticated technology and allows for quick and reliable installation in tight spaces in local applications.

Working with pre-assembled lines in connectors whose maximum dimensions match those of a standard M8 connector results in fewer wiring mistakes despite the considerably faster assembly times. Entire machine modules can be wired much faster and taken into productive use far more easily. So it's obvious that maintenance and tooling work are also much more straightforward.

Product manager Andreas Hoffmann describes this unique and customer-focused functionality as follows: "Right from the start of the project, the HD modules have been a key element of the overall "u-remote" concept. In all detailed developments in our system, we offer our customers solutions to problems in those areas where they encounter major challenges in machine automation. Such challenges range from restricted installation space to solutions for complete reviews of project run times and maintenance costs. The HD modules are a logical - almost indispensable - next step."

In this context, the functionality of "u-remote" can be further expanded. In tough everyday machine use, sensor and actuator failures are a routine occurrence for machine operators.

Environmental influences, friction, power surges, and much more, impact on connection technology in the field and continually subject it to damage. Detecting such damage in a targeted way and diagnosing it as e.g. wire breakage or short-circuit is another job of the new "u-remote" input and output modules with individual channel diagnosis. At the level of individual sensors/actuator, the module reports the current function status to the control.

This can then be used as a detailed source of information should maintenance be required, e.g. information about the precise location of line damage. This allows the service technician to work efficiently when replacing defective components and saves him the job of laborious analyses.

The "u-remote" functions are rounded off by modules with frequency counter technology. In many cases, information in the PLC relating to current speeds, flow rates or even angle changes in incremental or speed transmitters are indispensable for precise system control. But this information cannot be recorded with standard functions, so a function for this specific purpose has been added to the "u-remote" module portfolio. The corresponding input module records signals in a range of 0.1 to 100 kHz from any source and can therefore be used universally for a wide range of frequency-dependent automation applications.

These detailed innovations allow Weidmüller to strengthen its claim of giving its customers the greatest possible project and automation performance coupled with simplified I/O technology handling with "u-remote".
