WOW “Remote I/O System “u-remote” high density modules and superior features helps increase your space, time and maintenance efficiencies ”
At Weidmuller, our HD modules have raised the bar in modern I/O technology which means that 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 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 the 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.
It is in this very area that we have been 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 more quickly and put into productive use far more easily. It also means that maintenance and installation work are a good deal more straightforward.
Product manager Andreas Hoffmann describes this unique and customer-focused functionality: “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 step.”
Indeed, in tough everyday machine use, sensor and actuator failures are a routine occurrence for machine operators. Such things as environmental influences, friction, power surges, etc, impact on connection technology in the field and continually subject it to damage. “u-remote” input and output modules with individual channel diagnosis means such damage can be detected and diagnosed as, for instance, a wire breakage or short-circuit.
At the individual sensor/actuator level, the modules are able to report the current function status to the control. This can then be used as a detailed source of information should maintenance be required, with for example, information about the precise location of line damage. This allows a service technician to work efficiently when replacing defective components and saves time that would have been taken on labour-intensive analyses.
“u-remote” also incorporates 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. This information can not normally be recorded as standard, but “u-remote” has had a function specifically included for this purpose within its 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.
