Temperature Monitoring Relays3RS10/3RS11Overview The 3RS1/3RS2 SIMIREL temperature monitoring relays can be used for measuring temperatures in solid, liquid and gaseous media. The temperature is acquired by the sensor in the medium, evaluated by the device and monitored for overshoot, undershoot or within a range (window function). The family consists of analog adjustable devices with one or two threshold values and digital devices that represent an excellent alternative to thermostats in the low-end performance range. The output relay picks up and releases at the threshold values in accordance with the parameter settings. Analog evaluation units Sensor types: PT100/Type J/ Type K Measuring principle for 2- and 3-wire sensors Electrical isolation between sensor and supply voltage (with the exception of AC/DC 24 V devices) Separate designs for overshoot an
