The ReeR SR Series Safety Interfaces are a range of dedicated safety relay interface modules designed to connect safety devices with OSSD or contact outputs to machine control systems. These modules act as an intermediary layer between devices such as safety light curtains, emergency stop buttons, safety switches and two-hand controls, ensuring safe signal processing and reliable machine shutdown when a hazardous condition is detected. The SR Series includes multiple specialized models such as SR ZERO, SR ONE, SR E4, SR X, SR T and SR SELECT, each tailored for specific applications.
The series supports high safety levels up to PL e and SILCL 3, with features such as EDM feedback monitoring, manual or automatic restart, muting functions and guided contact safety relays. Designed for simplicity and reliability, these modules do not require programming and are typically mounted on DIN rails for easy integration. With fast response times of ≤ 20 ms and standardized 24 V DC supply, the SR Series provides a cost-effective and robust solution for small to medium safety systems where a full safety PLC is not required.
