Product Positioning
The 3UG4631-1AA30 is a low-voltage monitoring relay from the Siemens SIRIUS series. It measures AC/DC 0.1 to 60 volts and is designed with a fixed AC/DC 24-volt power supply, making it suitable for low-voltage monitoring applications where the control power supply has been standardized to 24 volts.
Core Product Advantages and Features
Fixed 24-volt power supply
The control power supply adopts a fixed AC/DC 24V design, which is suitable for automation systems that have uniformly adopted 24V control power supply.
Low voltage range monitoring
Measurement range: AC/DC 0.1 to 60 volts; dual overvoltage and undervoltage protection thresholds can be set.
Screw terminal wiring
It adopts a screw-type terminal design, which can secure solid wires from 0.5 to 4 square millimeters, making wiring construction convenient and reliable.
Adjustable lag and delay
The hysteresis value can be flexibly adjusted from 0.1 to 30 volts and the action delay from 0.1 to 20 seconds, depending on the application requirements.
