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 parameter limits for speed, network quality, current, power factor or voltage.
The Sirius 3RS14 and 3RS15 temperature monitoring relays have between one and three resistance sensors or thermocouples for controlling temperatures from -99°C to 1,800°C, and can also be used for simple control tasks. The new monitoring relays can also fulfil their monitoring tasks reliably without an IO-Link connection to a controller.
Connecting the new Sirius relay via an IO-Link to the control level enables efficient, central parameter assignment and detailed fault localisation and diagnostics. This simplifies commissioning and maintenance. The devices have several LEDs and a display for showing actual values.
