SIRIUS 3UG5 monitoring relays
The SIRIUS 3UG5 monitoring relays for electrical and mechanical quantities enable constant monitoring of all important characteristic quantities that provide information about the reliability performance of the plant. Both sudden disturbances and gradual changes, which may indicate the need for maintenance, are detected. Thanks to their relay outputs, the monitoring relays permit direct disconnection of the affected system components as well as alerting (e.g. by switching a warning lamp).
Thanks to adjustable delay times the monitoring relays can respond very flexibly to brief faults such as voltage dips or load changes. This avoids unnecessary alarms and disconnections while enhancing plant availability.
The individual 3UG5 monitoring relays offer the following functions in various combinations:
- Undershooting and/or overshooting of limit values for voltage for 1-phase monitoring
- Undershooting and/or overshooting of the frequency
- Power monitoring
- Undershooting and/or overshooting of limit values for current
- Undershooting and/or overshooting of power factor limit values
- Monitoring of the active current or the apparent current
- Monitoring of the residual current
- Undershooting and/or overshooting of the liquid level
- Undershooting and/or overshooting of limit values for speed
The device family comprises devices with fixed function, analogically adjustable and digitally adjustable devices that can be parameterized using an intuitive LC display. Further versions with Bluetooth, Safety certification and for IO-Link are available.
Note:
The SIRIUS 3UG5 relays supersede the predecessor 3UG4.
Exception: 3UG4 insulation monitoring relay, see SIRIUS 3UG45, 3UG46 monitoring relays for stand-alone installation → Insulation monitoring.
Devices with fixed function or analogically adjustable devices
P_IC01_XX_01013
SIRIUS 3UG5512 and 3UG5514 relays
In addition to devices with a fixed function, such as 3UG5511 and 3UG5512, there are analogically adjustable devices, such as 3UG5514, whose parameters are set using potentiometers.
Digitally adjustable devices

SIRIUS 3UG5616 relays
Using the display, the digitally adjustable relays, such as SIRIUS 3UG5616 or 3UG5618, can be simply and intuitively parameterized via a menu and four buttons.
Devices with Bluetooth
G_IC01_XX_00899
Parameter assignment via Bluetooth with SENTRON Powerconfig app
The 3UG5716 and 3UG5742 relays can also be supplied with Bluetooth. They can be easily parameterized using a smartphone with the SENTRON Powerconfig app. This provides a clearer way of setting the parameters. It is also possible to transfer parameter assignments already made to several devices.
Devices in the Safety version
Selected devices are available with Safety certification up to SIL 1/PL c according to IEC 62061/IEC 61508 or ISO 13849-1.
Digitally adjustable devices for IO-Link
G_IC03_XX_31686
SIRIUS 3UG5816 relay for IO-Link
Most functions are available as versions for IO-Link. This enables simple connection to the controller and use of the measured values of the device, for example, for maintenance.
Note:
The IO-Link devices can be reset on the display or via IO-Link.

Notes:
Devices required for communication via IO-Link:
Each monitoring relay requires an IO‑Link channel.

Notes on security
In order to protect plants, systems, machines and networks against cyber threats, it is necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial cybersecurity concept. Siemens products and solutions represent one component of such a concept.

The SIRIUS 3UG5 monitoring relays monitor the most diverse electrical and mechanical quantities in the feeder, and provide reliable protection against damage in the plant. For this purpose, they offer freely configurable limit values and diverse options for adapting to the respective task, and in the event of a fault, they provide clear diagnostics information.
The digitally adjustable products also display the current measured values direct on the device. This not only facilitates the display of valuable plant status information during operation, it also enables adjustment of the monitored limit values in accordance with the actual conditions.
The positive result: More selective avoidance of production faults – sustained increases in availability and productivity.
The 3UG5 monitoring relays are available for the following applications:
- Line monitoring
- 1-phase voltage monitoring
- 1-phase current monitoring or power factor and active current monitoring
- Load monitoring
- Residual current monitoring
- Level monitoring
- Speed monitoring
Selected devices are approved for applications up to SIL 1 according to IEC 62061/IEC 61508 or PL c according to ISO 13849‑1.
