3RS1020-1DD00 SIEMENS

The 3RS1020-1DD00 from Siemens is a temperature monitoring relay designed for precise thermal management in industrial applications. It utilizes a PT100 sensor input to accurately measure temperature, providing reliable and continuous monitoring. This relay features the capability to set two independent threshold values, enabling users to define specific temperature limits for overshoot conditions. When either of these thresholds is exceeded, the relay triggers an alarm or initiates a control action. With a narrow width of just 22.5 mm, the 3RS1020-1DD00 is suitable for installations where space is limited. It operates within a temperature range of -50°C to +50°C, making it suitable for diverse environments. The relay is powered by a 24 V AC/DC supply and includes one normally open (NO) contact and one changeover (CO) contact for versatile output options. Connection is facilitated through screw terminals, ensuring secure and reliable wiring. It is ideal for preventing overheating in motors, transformers, and other critical equipment, enhancing operational safety and preventing costly downtime.
