Highly robust ProfiNet I/O modules

6 February 2008 Computer/Embedded Technology

Murrelektronik has expanded its MVK Metal product range by adding digital I/O modules with ProfiNet interface. All modules have an integrated Ethernet switch and support the automatic topology recognition protocol LLDP (Link Layer Discovery Protocol). This simplifies system start-up and also maintenance operations. Thanks to their robust metal housing and the proven M12 connector technology with IP67 protection, the modules are also suited to applications with high vibration and impact loads during operation and applications requiring welding strength.

The MVK Metal ProfiNet is equipped with diagnostics comprising port-related turnoff in case of error, as well as single-channel diagnostics. Overloads, short circuits on the sensor, and cable breaks are independently monitored for every individual channel. Errors are indicated by an LED and reported to the control without interfering with the adjacent channels.

In addition to a digital input module, a multifunctional module is available that allows each channel to be independently configured as input or output.
