3RS1000-2CK20 SIEMENS

The 3RS1000-2CK20 is a temperature monitoring relay designed for PT100 resistance thermometers, ensuring precise temperature control and protection. This relay features overshoot monitoring of a single threshold value, providing reliable detection of temperature excesses. With a narrow width of 22.5 mm, it is suitable for space-saving installations in control panels. The operating temperature range spans from 0°C to 200°C, accommodating a variety of industrial applications. It supports a wide voltage range of 110-120/220-240 V AC, offering flexibility in power supply options. The relay operates on the quiescent current principle, enhancing safety by triggering an alarm in case of sensor or wiring faults. Equipped with spring-type terminals, it ensures quick and secure connections, reducing installation time and effort. It includes one normally open (NO) and one normally closed (NC) contact, providing versatile signaling capabilities for control and alarm circuits. This temperature monitoring relay is ideal for preventing overheating and ensuring the reliable operation of critical equipment.
