Functional block diagram of the S16/U relay
General presentation
The S16/U relay is mainly used as main or back-up protection against voltage or frequency variations in industrial or commercial installations.
The relay has 4 voltage inputs (phase-earth).
The devices of the SMARTLINE range, S16 series, are designed to provide compact, economical and simple solutions for feeder protection, motor protection and various types of back-up protection. These devices feature a predefined hardware layout and fixed standard configurations.
The relay is fitted with a USB 2.0 port at the front and a serial interface at the rear. The front port gives access to the device configuration, which the user can modify (thresholds, time delays, signalling, tripping matrix, etc.) using the S16 Tool software, available for free download on our website. The communication port at the rear of the device is reserved for the connection to the SCADA system (IEC 61-870).

Applications
The S16/U relay is a three-phase and earth voltage protection. Its three-phase unit allows it to monitor voltage and frequency variations in substations of any voltage level. Its simplicity of use and operation makes it a relay suited to any type of application.
Protection and control functions
- Two undervoltage thresholds
- Two overvoltage thresholds
- One negative sequence overvoltage threshold
- Two residual (zero sequence) overvoltage thresholds
- Two overfrequency thresholds
- Two underfrequency thresholds
- One rate of change of frequency threshold
- One vector shift threshold
- One circuit breaker failure function
