Widely Applicable Safety Signal Processing

　　The new generation of safety relay modules, the PROTECT SRB-E series, comes in 8 models, achieving safety ratings of Cat.4 / PLe (compliant with EN ISO 13849-1 standard) and SIL 3 (compliant with EN 62061 / IEC 61508 standard).

　　The key advantages of the new PROTECT SRB-E series lie in its versatile design, allowing each SRB-E base model to replace dozens of existing SRB modules. Each module can be easily configured for up to eleven different applications through simple dial settings. All conventional safety sensors and electromechanical safety devices can be monitored.

　　The significant reduction in model variants and the clear display of related functions make it easy for equipment manufacturers and users to select the correct module for their specific applications. For instance, the start/reset detection function can be set by rotating the dial.
