The PNOZ s50 is a dedicated safety relay designed for safe, contactless control of two brakes up to PL e. It ensures fast, reliable braking in emergencies and low-wear switching in normal operation, offering energy-efficient performance, rapid diagnostics, and broad application flexibility.
The PNOZ s50 safety relay provides high-performance and reliable brake control for both safety brakes and holding brakes, ensuring maximum protection for operators and machinery. Its ability to safely control two independent brakes up to PL e makes it an ideal solution for a wide range of applications, including gravity-loaded axes and systems requiring precise braking performance.
The relay uses temporary overexcitation followed by a user-configurable voltage reduction, achieving shorter ventilation times and lower energy consumption. This enables rapid braking during emergency situations while ensuring gentle, wear-minimizing operation during normal use, ultimately reducing maintenance and extending the service life of the brakes.
Featuring contactless switching technology with up to 4.5 A per brake, the PNOZ s50 provides fast response times and wear-free operation. Easy parameter setup and clear diagnostics through the integrated display ensure efficient commissioning and troubleshooting. Its safe digital inputs allow manufacturer-independent operation, providing great flexibility in machine integration.
The PNOZ s50 is well-suited for applications involving gravity-loaded and Z-axis movements, including stage winches, palletisers, milling machines, robot axes, scissor tables, machine tools, packaging equipment, materials handling systems, and energy/environmental machinery. It provides reliable, simultaneous control of dual brakes—especially valuable in applications like winches and lifting systems where enhanced safety is required.
