The SIRIUS 3TK2826-2BB40 is a phased-out safety relay from Siemens, now superseded by the 3SK2 series (refer to FAQ 109741483 for details). This safety relay features relay enabling circuits (EC) and operates on a 24 V DC power supply. Its compact design, with a width of 45 mm, makes it suitable for various applications. The relay utilizes spring-type terminals for secure and efficient connections. It provides instantaneous enabling circuits with 4 normally open (NO) contacts and does not offer any delayed enabling circuits. The device incorporates 3 safety circuits and offers a switch with 8 functions, serving as a basic unit for safety implementation. According to EN 13849-1, it can achieve a maximum Performance Level (PL), and according to IEC 61508, it can achieve a maximum Safety Integrity Level (SIL) of 3. This safety relay is designed to enhance safety in machinery and equipment by providing reliable monitoring and control functions. It ensures that safety-related functions are activated when hazardous conditions are detected, contributing to a safer working environment.
