Weidmüller has annouced its latest HD modules. Four lines with wire cross-sections of 0.14 to 0.32mm2 can be connected to every single HD connector, producing 32 connection points on what is already the narrowest module width on the market at just 11.5mm. Connection density goes hand in hand with system structure flexibility: there is enough room on these HD modules for all the wiring for eight individually pluggable sensors or actuators.
This plug & play solution 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.
Environmental influences, friction, and power surges, 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 u-remote input and output modules with individual channel diagnosis. At the individual sensor/actuator level, 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.
The u-remote functions are rounded off 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 100kHz from any source and can thus be used universally for a wide range of frequency-dependent automation applications.
Andreas Hoffmann, Product Manager, Weidmüller, comments: "Right from the start of the project, the HD modules have been a key element of the overall u-remote concept. All developments of our system 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."
