The Siemens 7SR catalog features a range of protection relays, primarily designed for overcurrent and transformer differential applications. These relays commonly incorporate binary inputs and outputs, LED indicators, and measuring inputs for current and voltage. Standard communication interfaces include USB front ports and RS485 rear ports, with some models also offering rear electrical Ethernet and optical LC interfaces. Auxiliary voltages typically range from 24 to 250V DC, and many models support IEC 60870-5-103 and Modbus RTU protocols.
