Automation direct safety monitering relays are mainly applied to the safety control circuit, connecting the safety sensing elements and mechanical equipment motion controller. The working principle of safety relay interlock system: when there is a fault in the safety circuit, the intrinsically safe barrier relay automatically detects the fault and stops the machine movement, to protect equipment and personnel safety.

Chenzhu solid state safety relay is the first product to get  PLe/Cat.4, SIL3 certified in China mainland. Automation and safety is the main character of the programmable safety relay module that you can be assured.

Various safety relay products are available for you to select. We have safety relay for E-stop buttons, emergency stop buttons, two-hand control buttons. We also provide light curtain safety relay, sil 2 and sil 3 rated relays to better meet the needs of our customers. For more information, please feel free to contact us.

FAQ of Safety Relay

What is safety relay?-

Safety relay offer an extra level of protection usually through a redundant wiring system.

These relays are used to enable an monitor the signals between other safety devices such as safety switched sensors, light curtains, intrinsic safety barriers and isolators. In many cases, the safety relay can be paired with a safety PLC configurable safety relay or safety controller.
