Siemens 3SK1111-1AB30

The Siemens SIRIUS safety relay is a robust and reliable component designed to enhance safety in industrial applications. This standard series device features 3 normally open (NO) contacts and 1 normally closed (NC) contact, providing effective relay enabling and signaling circuits. With a control supply voltage of 24V AC/DC and screw terminal connections, it ensures easy and secure installation.

Designed for high performance, the relay offers IP20 protection and is finger-safe to prevent electrical shock. It operates efficiently in a wide range of temperatures, from -25°C to +60°C, and can withstand storage temperatures as low as -40°C and as high as +80°C. The relay is built to endure harsh conditions, with vibration resistance up to 500 Hz and shock resistance of 10g for 11 ms.

Compliant with IEC 60947-5-1 and IEC 61000 standards, the Siemens SIRIUS safety relay is suitable for Class B environments, including domestic settings. It supports both single-channel and two-channel safety-related wiring, ensuring flexibility and reliability in various applications. The relay also boasts a Safety Integrity Level (SIL) 3 and a Performance Level (PL) e according to EN ISO 13849-1, with a Safe Failure Fraction (SFF) of 99%.

With a mechanical service life of up to 10 million switching cycles, this safety relay is built to last. It features a maximum switching capacity of 5A at 24V DC and 5A at 230V AC for NO contacts, and 1A at 24V DC and 1.5A at 230V AC for NC contacts. The relay also...
