Temperature monitoring relay with display for resistance temperature sensors and thermocouples, AC/DC 24 V, width 22.5 mm, 2 changeover contacts, screw connection Temperature monitoring relay SIRIUS 3RS2 for measuring temperatures in solid, liquid and gaseous media, e.g. for controlling and regulating processes or for protecting motors and systems from inadmissible temperatures.The devices are easy to operate without complicated menu navigation. The temperature is displayed on a 3-color LCD display. The relays with two threshold values are suitable for all common sensor types, such as PT100, PT1000, KTY, NTC, thermocouple.The family of 3RS temperature monitoring relays consists of analog and digitally adjustable relays for connecting one to three sensors (resistance sensor or thermocouple). They are available with removable screw or spring-loaded terminals. Versions with communication via IO-Link are also available.Accessories include labels and insertion tabs.SIRIUS Relays - a program for all situations.
