SIRIUS safety relay safety-related standstill monitoring DC 24 V, 45 mm screw connection FK undelayed: 3 S + 1 Oe FK delayed: 0 MK: 3 Auto-start basic device max. error cat. EN 954-1: 4 maximum achievable PL according to EN 13849-1: e maximum achievable SIL according to IEC 61508: 3 Standstill monitor SIRIUS 3TK2810-0 for safe standstill monitoring of motors. The device can be used flexibly with various motors and frequency converters and has an adjustable standstill delay. It is cost-effective because no additional sensors are required. Higher system availability is achieved through rapid error diagnosis and display on error LEDs. The devices are available with different voltages and with screw or spring-loaded connections. Accessories such as labels make handling easier. Safety is a SIRIUS business.
