Product Page: MINOS SD1K - Safe Coupling Relay


MINOS SD1K is a safe coupling relay for contact reinforcement of safe outputs (e.g. safe PLC outputs) to machines and plants.

This module is also certified for the use in furnaces in continuous operation according to EN 50156-1 as well as EN 746-2. For use in the process industry these modules are certified according to IEC 61511-1.

The safe coupling relay SD1K is for:

  • the coupling of safety related signals, for example output signals of a safe control system to the periphery
  • the safe galvanic isolated contact reinforcement and contact multiplication
  • the test pulse filtering of safe PLC control systems
