SIEMENS 3RS1000-1CK20 SIRIUS Temperature monitoring relays analog adjustable for 1 Sensor

Temperature Monitoring Relay for Pt100, exceeding of 1 threshold value, width 22,5mm 0-200°C, AC 110-120/220-240V 1-NO and 1-NC, closed-circuit principle, screw-terminal



The 3RS10/3RS11 analog temperature monitoring relays can be used for measuring temperatures in solid, liquid and gas media.

The temperature is sensed by the sensors in the medium, evaluated by the device and monitored for overshoot or undershoot.

When the threshold values are reached, the output relay switches on or off depending on the parameterization.


  • All devices except for 24 V AC/DC feature electrical separation

  • Extremely easy operation using a rotary potentiometer

  • Adjustable hysteresis

  • Adjustable working principle for devices with 2 threshold values

  • All versions with removable terminals

  • All versions with screw terminals, many versions alternatively with cage-clamp-terminals
