Description

New family of safety relay modules with eight basic versions 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 existing SRB modules can be replaced thanks to the multi-functionality. 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 as well as a clear product-accompanying display 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 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.
