The main features of safety relays include:
1. Forced guided contacts: ensure that normally open and normally closed contacts are not connected at the same time, which helps with fault detection.
2. Redundant design: internal multi-channel circuits to improve fault tolerance.
3. Self-check function: automatically check the wiring and contact status when power is on to ensure system safety.
4. Compliance with safety standards: meet international safety standards such as EN ISO 13849-1 and IEC 62061.
5. Compatible with a variety of safety inputs: such as emergency stop buttons, safety light curtains, safety door switches, etc.
6. Quick disconnect output: quickly cut off dangerous power in abnormal situations to ensure personnel safety.
These features make it an indispensable core component in industrial safety control systems.
