Siemens 3RS1100-1CD30

The Siemens 3RS1100-1CD30 is a temperature monitoring relay designed for use with Type J thermocouples. It features a compact 22.5 mm width and measures temperatures ranging from 0 °C to 600 °C. The relay operates on a 24 V AC/DC power supply and includes one normally open (NO) and one normally closed (NC) contact, configured with screw terminals for secure wiring. This device utilizes an overshoot threshold monitoring principle to ensure precise temperature control. While the 3RS1100-1CD30 has been phased out, its recommended replacement is the Siemens 3RS2500-1AA30.
