Siemens 3RS1101-1CD20 Temperature Monitoring Relay | K Thermocouple | 0-200°C

The Siemens 3RS1101-1CD20 is a temperature monitoring relay designed to detect temperature excursions using a Type K thermocouple. It features a single threshold value adjustment for overshoot monitoring, with a temperature range of 0°C to 200°C. The relay operates on a 24V AC/DC supply and provides one normally open (NO) and one normally closed (NC) contact. It utilizes the quiescent current principle for reliable operation and connects via screw terminals. This is a phased-out product, with the preferred successor being the 3RS2500-1AA30.

This temperature monitoring relay is suitable for applications where precise temperature control and safety are required, such as in heating systems, industrial ovens, process control, and machinery where overheating could cause damage or hazards. Its compact 22.5 mm width makes it ideal for panels with limited space.
