SIRIUS 3RS Temperature Monitoring Relays
Fast fault diagnostics in various applications
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.
Increase your productivity
With the SIRIUS 3RS temperature monitoring relay!
Benefit from high operating safety and save time, thanks to easy parameter assignment and the optional spring-loaded terminal connection, which allows for fast wiring
Save costs too, with the digital relais for two- or three-step control, which does not require any additional, expensive controller
Ensure a continuous production process in your plant, thanks to reliable diagnostics and data processing based on the open industrial communication standard IO-Link as well as removable terminals for fast device replacement

SIRIUS Temperature Monitoring Relays for IO-Link
For seamless industrial communication
The relays SIRIUS by Siemens offer maximum machine and system protection and now - thanks to IO-Link - also communicate with the control level. Enjoy greater flexibility with the monitoring relays SIRIUS for IO-Link: In addition to the unchanged autonomous monitoring function, measured values and data can directly be transmitted to the control via IO-Link. Also parameter assignment can either be done locally or via IO-Link. Benefit from considerably simplified device replacement – thanks to data synchronization and automatic parameter assignment via parameter server.
Available with IO-Link connection
