3RS1020-1DD20 SIEMENS

The 3RS1020-1DD20 from Siemens is a temperature monitoring relay designed for use with PT100 sensors. It provides precise temperature monitoring within a range of 0°C to 200°C. This relay features the capability to monitor for overshoot conditions using two independently adjustable threshold values. When a threshold is exceeded, the relay's output contacts change state, enabling prompt response to temperature deviations. The device operates on a 24 V AC/DC power supply, offering flexibility in various industrial applications. Its compact design, with a width of 22.5 mm, allows for space-saving installation on DIN rails. The relay includes one normally open (NO) contact and one changeover (CO) contact, providing versatile output options for signaling and control purposes. Wiring connections are facilitated through screw terminals, ensuring secure and reliable connections. This temperature monitoring relay is suitable for a wide range of applications where accurate and reliable temperature monitoring is crucial for process control and equipment protection. It is commonly used in industries such as manufacturing, HVAC, and power generation.
