Working Mechanism

  • The safety relays' internal logic monitors the safety circuits and activates the enabling-current paths in the absence of any faults.
  • The enabling-current paths are disabled if the safety device has been engaged or if there is a fault.

Standards and Approvals

  • CE
  • UL
  • cUL
  • CSA
  • IEC

Frequently Asked Questions

What is the difference between an electromechanical safety relay and a solid-state safety relay?

An electromechanical safety relay uses mechanical components to perform its safety functions, while a solid-state safety relay uses electronic components.

What is the difference between a safety relay and a general relay?

A safety relay specifically provides safety functions in response to safety inputs, while a general relay is designed for general-purpose switching applications.

When should I use a safety relay?

Use a safety relay when the load cannot be activated directly by a safety controller that is not able to handle the power needed to switch the load or when more contacts are needed to be driven by the same control signal.
