Light Curtain Safety Relay, For Dual-output Safety Light Curtain Sensor

Introduction:

• A light curtain safety relay is a control unit that works in conjunction with a dual PNP or NPN output safety light curtain to indirectly control the start and stop of a motor. Unlike commonly used general-purpose relays, it is safer and specifically designed for high-standard safety protection applications.
• It delivers superior safety compared to conventional intermediate relays for two key reasons: 1. Once the safety light curtain is triggered, the relay locks off its output automatically. The system can only be reset manually by pressing the connected emergency stop button. 2. Additionally, it adopts an internal redundant circuit design to ensure reliable and enhanced safety protection.
• Lorentzzi brand light curtain safety relays come in 6 models(You can see more details by reading our safety light curtain relay user manual), which can be used not only with safety light curtains of different heights, but also with safety doors, emergency buttons, etc., to stop the machine when a person or object enters the danger zone.
• Whether your safety light curtain sensor output is dual PNP or NPN, our SC4P3A1B24 safety light curtain relay is compatible. It features four control channels: one normally closed (NC) contact and three normally open (NO) contacts. Its wiring diagram is as following:

• • If you want to use it with the photoelectric sensors to realize muting function, you can try to use our SC4P2A1B24P-M model safety relay.
