MURRELEKTRONIK’S new MVK Metal series is a surface-coated, one-piece, die-cast housing that is fully encapsulated, fulfilling even the highest requirements in a rugged environment. Thanks to its resistance to vibration (vibration 15g and shock 60g), the robust field bus module is well suited for use under the most extreme conditions, such as those found in press technology. The product is available from SICK .
The demands made on I/O products in the field today are tremendous. Aside from the requirements of IP67 class protection or better, requirements for higher vibration stress and welding stability are being made more and more frequently. The MVK Metal series meets these requirements.
Customers do not have to do without the single-channel diagnosis that is typical of the MVK products. Overload, sensor short circuit and cable rupture are monitored for each channel separately and reported to the controls, without affecting the neighbouring channels.
The MVK Metal series is available for Profibus and DeviceNet. In addition to a standard input module, there is also a free programmable module available, in which each pin can be configured individually as an input or output, and that for both pin 4 and pin 2 of the each port.
A special feature of the product is the capability of automatic replacement of the input and output modules by the multifunctional service module. The advantage for the user is that only this ‘service module’ need be stocked. When service becomes necessary, the service module, for instance, can replace the input module. The service module is self-configuring and behaves just like the replaced module. This lowers storage costs and simplifies service.
