Wieland SNO 4083KM-A | Safety relay with 3NO+1NC outputs for 4-wire mats, bumpers, and edges – R1.188.3580.0

The Wieland SNO 4083KM-A (R1.188.3580.0) is a high-performance safety relay designed specifically for 4-wire pressure-sensitive mats, bumpers, and switching edges. Operating at 24V DC, this relay features 3 normally open (NO) contacts and 1 normally closed (NC) contact, making it ideal for emergency stop applications. Complying with EN 60204-1, the SNO 4083KM-A performs self-monitoring during each ON-OFF cycle, ensuring reliable operation and safety. With a response time of 1.5 seconds, it is equipped with screw terminals for secure and efficient connections. This safety relay is engineered for use in series configurations, eliminating the need for a monitoring resistor, thus providing a streamlined solution for integrating safety devices in industrial environments.
