Description

The SIRIUS 3TK2828-2BB41 safety relay is a robust control device tailored for industrial safety applications requiring precise and reliable performance. Designed with relay enabling circuits (EC), it operates on a 24 V DC supply and features a compact overall width of 45 mm. The unit integrates spring-type terminals for secure connections, simplifying installation processes in diverse system environments.

The safety relay offers two instantaneous EC normally open contacts (NO) and two delayed EC NO contacts with adjustable time ranges from 0.05 to 3 seconds, providing flexibility across various automation setups. Additionally, it includes one normally closed contact (NC) dedicated to safe control functionalities and supports AUTOSTART capabilities.

Engineered to meet stringent international safety standards, the device achieves Safety Integrity Levels (SIL) up to SIL 3/2 and Performance Levels (PL) e/d as defined by IEC standards, making it suitable for high-demand applications in machinery safeguarding and process monitoring.

With packaging dimensions of 115.50 x 53.00 x 125.00 mm and a net weight of approximately 0.440 kg, this product delivers ease of transport and space-efficient integration into control panels or enclosures where size constraints are critical.

Engineers examining lifecycle considerations should note that the product is discontinued; however, there is an identified successor model, the SIRIUS SAFETY RELAY 3SK1121-2CB41 that further enhances functionality aligned to current technology standards.
