The Bernstein SCR P series is a programmable safety controller designed as a smart, cost-effective alternative to traditional safety relay modules. With its wide range of applications, it can replace multiple safety relay modules, saving not only cost but also time, wiring effort, and panel space. The SCR P is particularly suitable for larger machines with multiple safety components or SRF safety sensors.

Key Features

• High Safety Integrity: Certified up to Category 4, PL e (EN ISO 13849-1), ensuring compliance with the highest safety standards for machinery safety functions.
• Multiple Safety Circuits: Supports up to 5 safety circuits, with 2 circuits featuring innovative DCD (Daisy Chain Diagnostics) for logical connections and targeted shutdown of specific machine areas.
• Flexible I/O Configuration: Provides 6 safety inputs, 4 configurable I/O points (can be used as safety inputs or non-safety outputs), and 2 independent relay outputs, each with 3 enable paths (3 NO contacts).
• Comprehensive Diagnostics: Extensive diagnostic information can be retrieved via the Ethernet interface. The DCD system allows detailed status and performance information from connected devices to be evaluated.
• Easy Configuration: Bernstein SCR P software enables quick and intuitive configuration via drag-and-drop, supporting logic and safety function blocks. Simulation mode allows testing before deployment, and live mode facilitates troubleshooting.
• Space-Saving Design: Compact DIN rail-mountable housing (100 × 45 × 115 mm) minimizes panel space requirements.
