Safety Relay

• 

Automation direct safety 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 system: when there is a fault in the safety circuit, the intrinsically safe barrier relayautomatically detects the fault and stops the machine movement, to protect equipment and personnel safety.

Chenzhu solid state safety relayis 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. Chenzhuhassafety relay for E-stop buttons, emergency stop buttons, two-hand control buttons. We also provide light curtain safety rated 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.

Safety Relay Types

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.

What is the difference between safety relay and normal relay?-

Compared to a normal relay, a safety relay have mandatory steering contact arrangement assures protection when contact fusion happens. A safety relay is a module composed of multiple relays and logic circuits. It is a circuit composition unit. In order to achieve the correct and low malfunction feature and to minimize errors and failure values, and complete each other's faults in a fault state to enhance safety factors.

How does an intrinsically safe barrierwork?-

Safety relays are generally composed of two or more relays and electronic circuits, so as to complement each other's abnormal defects. Even if any component fails, it can diagnose the failure and enter a safe state. And it will not affect the shutdown instructions issued to the machine, ensuring the safety of production. From the structural point of view, the safety relay generally adopts a dual-channel structure, and the channels can diagnose each other, and use a forced-oriented relay to realize the diagnosis of the output contact fusion fault.
