Erwin Sick has extended its range of Intelliface® safety interfaces into the most exciting area of safety technology development - the safety bus network. The first products to be announced are from the UE 1000 range and suitable for Profibus Safe systems. Further introductions are planned for ASi Safe later in the year.

The UE4150 IP67 Profibus node is released to coincide with the availability of Profibus Safe systems. This highly advanced bus module exploits all the advantages of Profibus and can co-exist on the same standard bus network as Profibus DP, removing the need for separate safety bus and control networks.

Having one single bus address, the UE4150 is an intelligent node and can be configured to handle intelligent SICK safety sensors such as the C4000 light grid and laser scanners. This allows complete diagnosis and configuration back up over the bus network, greatly increasing reliability over low complexity systems.

The IP67 housing means big savings over IP20 I/O modules mounted in panels, making the UE4150 a compact and cost effective option. Cabling is simple with all I/O and power requirements being handled by the UE4150, there are no other connections required.

The UE4150 bus node also has eighteen configurable active/passive inputs for other safety sensors such as Emergency stop buttons, interlock switches, reset button, indication lamps, enable switches and muting sensors. All of these items can be monitored and configured via a single address, making the UE4150 a powerful and flexible node for all applications.

As you would expect, the Intelliface bus nodes meet the latest safety requirements and are all certified to IEC 61508. They are suitable for sensors and applications from SIL 1-3 and EN 954-1, categories 2-4.
