This relay represents the pinnacle of hardware technology, featuring the latest advancements in its design. It comes in several variants, catering to various power supply requirements, binary input/output configurations, and data communication capabilities. Housed in a compact 4U high, size 4 non-draw-out case, these relays offer a comprehensive package, encompassing protection, monitoring, instrumentation, metering, integrated input/output logic, data logging, and fault reporting. Accessing and configuring the relay is made easy with a front USB port for local PC connection or, optionally, a rear electrical RS485 port for remote connectivity, ensuring seamless communication with the relay’s extensive functionality.

• The Reyrolle 7SR10 Argus boasts a versatile universal power supply that accommodates both AC and DC sources, making it adaptable to a wide range of power input options.

• Users can select between 1A and 5A current transformers (CT) on-site. The relay supports key communication protocols like MODBUS RTU and IEC 103, allowing users to choose as needed. It also features up to 6 digital inputs (DI) and 6 digital outputs (DO) for versatile control and monitoring capabilities.

• The 7SR1003 is tailored for current-based protection, while the 7SR1004 offers the added capability of voltage inputs for comprehensive protection. Meanwhile, the 7SR1005 is purpose-built for motor protection applications.

Functions Of Siemens Reyrolle 7SR1003 Overcurrent Numerical Relay

• Time-delayed derived/measured earth fault protection (51N/G) is a crucial safeguard in power systems, designed to detect and respond to ground faults with precision and reliability.

• Broken conductor, load unbalance protection (46BC) is a vital feature in power systems, designed to swiftly detect issues like broken conductors and load imbalances to prevent potential damage and outages.

• Negative phase sequence overcurrent protection (46NPS) safeguards power systems by detecting and responding to abnormal currents caused by phase imbalances, enhancing overall reliability.

• Instantaneous overcurrent protection (50) is a critical safety feature in power systems, designed to rapidly disconnect the circuit when excessive current levels are detected, preventing equipment damage and ensuring system stability.

• Circuit breaker fail protection (50BF) is a crucial safety measure that detects when a circuit breaker fails to open as expected, preventing potential hazards and equipment damage.
