Siemens Reliable IO-Link interface for Motors and Plant Components Monitoring

The Siemens Industry Automation Division has equipped its complete range of monitoring relays with the IO-Link interface. The relays protect motors and plant components reliably by monitoring parameters such as temperature, speed, network quality, current and voltage. The relays communicate with the control level via IO-Link to transfer, for example, measured values and messages. The Sirius 3UG48 monitoring relays for electrical and mechanical measurements monitor the observance of parameterizable limits for speed, network quality, current, power factor (cos phi) or voltage. The Sirius 3RS14 and 3RS15 temperature monitoring relays have between one and three resistance sensors or thermocouples for controlling temperatures from -99 to +1,800 degrees Celsius, and can also be used for simple control tasks.

The devices have several LEDs and a display for showing actual values and can be used directly in the control cabinet for diagnostic purposes. The values are also displayed in the central control system via the IO-Link for simple further processing. The new Sirius relays are parameterized either directly at the device or from the central control system via the IO-Link. Data synchronization with the higher-level control system ensures that the system documentation is up-to-date at all times. New parameters are automatically assigned by a parameter server, which makes it considerably easier to replace any devices. For efficient energy management, the Sirius relays 3UG48 also support the data formats defined in the Profienergy profile.
