3TK28101KA410AA0, Siemens
SIRIUS safety relay Safety-oriented Speed monitoring 110-240 V AC/DC, 45 mm overall width Screw terminal EC instantaneous: 2 NO EC delayed: 0 SC: 2 electrical NAMUR version Auto-start/manual start Basic device Maximum achievable PL according to EN 13849-1: e Maximum achievable SIL according to IEC 61508: 3 Speed monitor SIRIUS 3TK28 for reliable standstill and speed monitoring in machines and plants, e.g. with motors. The device is suitable for all commonly used sensors and has a release delay feature that can be set by the user. Through simple parameterization and permanent diagnostics on the display, faults can be quickly remedied at any time. Thanks to integrated protective door monitoring, the device ensures greater safety because access to the plant is allowed only in the safe state. Each device is available with various voltages as well as with screw-type or spring-loaded terminals. Accessories such as connecting cables, adapters and labels make handling easier. Safety is a SIRIUS business.
