PRESS RELEASE
Multifunctional PROTECT SRB-E
Schmersal launches a new range of safety relay modules on the market
Visit Schmersal at SPS IPC Drives from 24 to 26 November 2015 in Nuremberg:
Hall 9, Stand 460
Wuppertal/Nuremberg, 24 November 2015. The Schmersal Group is presenting a new family of safety relay modules with eight basic versions at the SPS IPC Drives trade fair.
All equipment versions can be employed in applications up to cat. 4 / PL e according to
EN ISO 13849-1 and SIL 3 according to EN 62061 / IEC 61508.
A major advantage of the new PROTECT SRB-E range is that, with each basic version, several dozen existingsafety relay modules can be replaced thanks to the multi-functionality of PROTECT SRB-E. Each module can be configured for up to eleven different applications via a simple control element. All conventional safety sensors and electromechanical safety equipment can be monitored.
The drastically reduced number of versions and a clear overview of the eight versions with their relevant functions makes it considerably easier for the machine manufacturer to select the right module for its particular application. Functions such as start/reset monitoring or cross circuit monitoring, for example, can be set via a rotary switch.
One version of the new PROTECT SRB-E range is also distinguished by p-type fail-safe power semi-conductor outputs up to 5.5 A. This SRB-E variant is particularly suited to fail-safe applications with high switching capacity in conjunction with short cycle times, for example switching valve terminals or complete output modules.
Other versions are equipped with a combination of secure relay outputs and Si-semi-conductor outputs of cat. 4 / PL e or with an input extension for up to four sensors, which can also be monitored up to a performance level of PL e.
A combined version makes it possible to monitor two safety functions with one device, such as a two-hand control panel and an emergency stop function. The fail-safe outputs which in each case are available separately can be linked by the user according to the application.
All PROTECT SRB-E versions are distinguished by very short response times in the requirements profile and signalise detailed diagnostic and status reports via LED displays.
Another bonus feature of the new PROTECT SRB-E range are the housings which have been optimised by Schmersal according to customer requirements. They are small, compact and feature a range of new, practical functions and properties such as a transparent front cover that can be secured with a seal as well as push-fit terminals.
The new SRB-E are designed to successively replace the existing series from Schmersal in the coming years, though these are still available until further notice.
