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.
