3RS1100-2CD20 SIEMENS

The 3RS1100-2CD20 is a temperature monitoring relay designed by Siemens for precise thermal management in industrial applications. This device utilizes a thermocouple type J sensor to accurately measure temperature within a range of 0 to 200 degrees Celsius. It features a single, configurable threshold value for overshoot detection, enabling proactive response to temperature deviations. The relay operates on a 24 V AC/DC power supply and employs a quiescent current principle, ensuring reliable operation and fail-safe behavior. Its compact design, with a width of 22.5 mm, allows for space-saving installation on standard DIN rails. The 3RS1100-2CD20 is equipped with one normally open (NO) and one normally closed (NC) contact, providing versatile switching capabilities for alarm systems or control circuits. Spring-type terminals facilitate quick and secure wiring, reducing installation time and enhancing connection reliability. This temperature monitoring relay is ideal for applications requiring accurate and dependable temperature supervision to protect equipment and processes. It offers a robust and user-friendly solution for preventing overheating and ensuring operational safety.
