Compact, modular safety technology for machine building

As a machine builder, you are familiar with the dynamics and requirements of your market. Functional safety plays an increasingly significant role in this area, while standards and directives also make an important contribution. With our PSR safety relays, you are able to create new safety concepts that provide many advantages:

  • Compatible with many sensors and actuators, so they can be used in countless applications, particularly in machine building
  • Able to realize applications up to performance level e in accordance with ISO 13849 and SILCL 3 in accordance with IEC 62061
  • All our safety products are TÜV-certified and come with extensive approvals for global markets
  • The Phoenix Contact relay technology installed in the safety relay (link to relay technology page) offers maximum functional safety with force-guided contacts
  • Our safety relays have an overall width starting from 6 mm, and a minimum of one enabling path make them suitable for modular safety concepts

Three product ranges for various machine applications

Our compact safety relays meet the demands made of machine building applications all over the world. They are used primarily in food, packaging, and assembly handling machines.
