Siemens 3RS1100-1CK20

The Siemens 3RS1100-1CK20 is a temperature monitoring relay designed for use with Type J thermocouples. This device allows precise temperature monitoring within a range of 0 °C to 200 °C and features an adjustable threshold with overshoot compensation. It is built with a compact 22.5 mm width and operates on a voltage supply of either 110-120 V AC or 220-240 V AC. The relay includes one normally open (NO) and one normally closed (NC) contact, making it suitable for various control applications. Connections are made through screw terminals, following the quiescent current principle for reliable operation. While this model is now phased out, BSP Automation offers it as well as its recommended replacement, the Siemens 3RS2500-1AW30, ensuring continued support for your temperature monitoring needs.
