Dual-channel Multifunctional Safety Relay With Reset Switch

Safety relays use redundant design (such as dual-channel signal monitoring), forced guide contact structure and self-test function to ensure that the circuit is forced to disconnect in the event of a fault, meeting safety standards such as ISO 13849; ordinary relays only realize circuit on and off, without a fail-safe mechanism, and cannot be used in personal protection scenarios.

Q: 1. What is the difference between safety relays and ordinary relays?

A: Safety relays use redundant design (such as dual-channel signal monitoring), forced guide contact structure and self-test function to ensure that the circuit is forced to disconnect in the event of a fault, meeting safety standards such as ISO 13849; ordinary relays only realize circuit on and off, without a fail-safe mechanism, and cannot be used in personal protection scenarios.

Q: 2. Which international standards must safety relays comply with?

ISO 13849-1 (Performance level requirements for mechanical safety control systems)
IEC 62061 (Functional safety assessment framework)
EN 60947-5-1 (Low-voltage switchgear specification)
IEC 61508 (Functional safety basic standard).

Q: 3. In which scenarios must safety relays be used?

A: High-risk equipment involving personal safety must be configured compulsorily, such as stamping machinery, collaborative robot workspaces, automated logistics sorting lines, injection molding machine protective doors, elevator emergency braking systems, etc.

Q: 4. Why can dual-channel design improve safety?

A: The dual channels detect contact adhesion or short circuit faults by cross-checking two independent signals. For example, when one signal is abnormal, the safety relay can trigger the redundant channel to cut off the power supply within 15ms to avoid the risk of single point failure.
