In industrial applications, the temperature of solid, liquid and gaseous mediums is the mainly measured parameter. Not only for this reason, the temperature monitoring relais SIRIUS by Siemens support you in protecting your plant the best possible way.

They monitor HVAC systems just as reliably as control cabinets or motors – if necessary with up to three sensors at a time. If the measured temperature lies above or below a certain critical value or leaves a specific operating range, the output relay either switches on or off at these threshold values – depending on the assigned parameters.

By detecting sensor wire break and short-circuit, our temperature monitoring relays allow for a quick error diagnostics at any given time.

The temperature monitoring relays SIRIUS are now also available for IO-Link – for seamless industrial communication.
