Siemens Industrial Controls 3UG5512-1AR20 Monitor Relay
The Siemens 3UG5512-1AR20 is a high-performance digital line monitoring relay designed for precise supervision of three-phase systems in demanding industrial and HVACR environments. Engineered for versatility, this unit supports a broad line voltage range of 160V to 690V AC, making it a reliable solution for monitoring phase sequence, phase failure, and phase asymmetry. Its digital interface allows for granular adjustment of undervoltage and overvoltage thresholds, ensuring critical motors and compressors remain protected against electrical irregularities. With two changeover contacts and a 50/60 Hz frequency tolerance, this S00 size monitoring relay integrates seamlessly into existing control circuits using standard screw terminal connections. By utilizing IO-Link communication, technicians can access real-time diagnostic data to streamline preventative maintenance and reduce system downtime. This Siemens monopolar relay is the industry standard for protecting expensive rotary equipment from improper phase rotation and voltage fluctuations.
Key Benefits for Technicians:- Broad Voltage Range: Rated for 160V to 690V, simplifying inventory by covering various commercial and industrial power configurations.
- Precise Digital Accuracy: Eliminates the guesswork of analog dials with digital setting of voltage asymmetry and response delay times.
- Advanced Protection: Actively monitors for phase reversal and total phase loss to prevent immediate motor burnout.
- IO-Link Integration: Supports smart building infrastructure by providing detailed fault logging and remote parameterization.
- Compact Form Factor: The S00 width ensures minimal footprint on the DIN rail within crowded control cabinets.
Does this relay require a separate control voltage?
No, the Siemens 3UG5512-1AR20 is self-powered via the measuring circuit, ensuring monitor continuity as long as the line is active.
Can this unit detect phase imbalances in variable frequency drive (VFD) applications?
Yes, it is designed to filter out typical harmonic interference while accurately measuring the true RMS voltage to identify genuine asymmetry issues.
What happens if the phase sequence is incorrect at startup?
The relay will immediately trip the output contacts and provide a visual fault code on the display, preventing the motor from rotating in the wrong direction.
