Certified with safety

samos® PRO COMPACT is also certified for your safety application.  

  • Elevators (EN 81/20, EN 81/50)
  • Presses (EN 692/EN 693)
  • Process industry (EN/IEC 61511)
  • Combustion plants (EN 50156/EN 746)


Scalable for your machine

Thanks to its high scalability, samos®PRO COMPACT is suitable for any system. Thus, our safety control can also be adapted to your machine size. 

Comfortable communication

Integrated Ethernet protocols ensure the communication of your machines. 

Integrated in the basic module: 

  • EtherNet/IP
  • Modbus TCP

Via external gateways: 

  • CANopen
  • EtherCAT

Flexible due to numerous interfaces

In addition to the Ethernet interface, samos®PRO COMPACT has mini USB and SD card ports. Your machine can thus be flexibly programmed and programs can be quickly duplicated or exchanged. This speeds up commissioning and reduces machine downtimes enormously. 

fast programmed, fast verified

In combination with our intuitive software samos®PLAN 6, the verification of your machine becomes child's play. Instead of programming safety functions, we rely on parameterization with certified function blocks, thus simplifying the approval process for you.
