Scalable

The flexible safety platform for demanding applications

The Scalable Safety Controller is a powerful, scalable hardware platform that can be expanded into a high-end safety PLC or a safe robot controller.
Thanks to modern multicore ARM architecture and an intelligent safety watchdog, the system is ideal for complex, modular, and performance-intensive safety applications.

Typical areas of application

  • Safety PLCs for modular machines
  • Safe robotics controllers
  • High-end OEM safety systems
  • Complex systems with multiple fieldbuses

Your benefits at a glance

  • Shorter time-to-market
    Pre-certified hardware for achieving high safety levels up to PL e (ISO 13849) or SIL 3 (IEC 61508-1) – significantly reduces development and certification costs.

  • High performance with minimal footprint
    A single powerful processor combines cost efficiency, low space requirements, and very low heat generation.

  • Modular & customizable
    Ideal for integration into existing standard designs – scalable for different performance and I/O requirements.

  • Flexible storage options
    Choice of internal memory or external memory via SD card.

Technical highlights

  • CPU:
    • Single quad-core ARM Axx CPU
    • With intelligent safety watchdog (Cortex-M3)
  • Clock frequency: up to 800 MHz
  • RAM:
    • 2 MB internal
    • Optional DDR3 expansion up to 4 GB
  • Digital I/Os:
    • Up to 48 digital TTL inputs/outputs
      Flexible configuration (e.g., 32 in / 16 out)
  • Sensor interfaces: 2 × SSI / BiSS-C (e.g., encoder)
  • Interfaces:
    • Ethernet
    • Two independent fieldbus protocols (separation of safety and standard communication)
    • USB (programming & parameterization)
  • Protective functions: Internal overvoltage protection for supply voltage
