- Application Case: In a power plant’s distribution substation, the REF620E_F NBFNAANNNCC1BNN1XF is used to protect and control the cable feeders. It can quickly detect faults such as overcurrent and earth faults in the cable feeders, and send out trip signals in time to isolate the faulty sections, effectively ensuring the safe operation of the power distribution system and reducing the impact of faults on the power plant’s production.
5. Competition Comparison
6. Selection Suggestions
- Compatibility: Consider whether the device is compatible with the existing power grid system and communication protocols to ensure seamless integration with the substation’s equipment and systems.
- Function Requirements: According to the specific protection and control requirements of the power grid, such as the need for specific fault detection functions and protection settings, select a device with appropriate functions. If the power grid has high requirements for power quality monitoring and protection against various faults, the REF620E_F NBFNAANNNCC1BNN1XF is a good choice.
- Installation Environment: Take into account the installation environment of the device, such as temperature, humidity and dust level. Although the REF620E_F NBFNAANNNCC1BNN1XF has good adaptability, it is still necessary to ensure that the installation environment meets the device’s operating requirements to avoid affecting its performance.
- Budget: Consider your project budget, but also balance the overall performance and quality of the product. The REF620E_F NBFNAANNNCC1BNN1XF offers high cost performance, providing reliable protection and control functions at a reasonable price.
7. Precautions
- Installation: When installing the device, make sure to follow the installation instructions provided by the manufacturer to ensure correct installation and wiring. Pay attention to the connection of terminals to avoid loose connections.
- Configuration: Before using the device, it is necessary to configure the protection settings and communication parameters correctly according to the actual power grid situation. Incorrect configuration may lead to incorrect operation of the device or failure to achieve the expected protection effect.
- Maintenance: Regularly check the operation status of the device, including the display screen, communication status and protection action records. Clean the device regularly to keep it free of dust and dirt. In case of any abnormal situation, contact the manufacturer’s technical support in time for troubleshooting.
IC660ELB912J
High-Speed Gigabit Ethernet Connectivity
The IC660ELB921M provides 1Gbps throughput and dual-port flexibility at approximately 1.5 times the cost of the single-port IC660ELB910, making it ideal for users with high-bandwidth needs. A German automotive assembly plant used 12 IC660ELB921M modules to build a gigabit Ethernet network for its RX3i-based production line control system: each module connected an RX3i rack (equipped with IC695CPU331) to 8 robotic arms and 2 HMI terminals. The 1Gbps throughput supported real-time transmission of robotic motion data (1000 data points per second per robot), and the dual-port design enabled separate networks for control and monitoring—reducing data latency by 70% compared to the IC660ELB910, ensuring precise coordination of the assembly line.
Redundant Ring Network for Uninterrupted Operation
Unlike single-port modules (where a cable break shuts down communication), the IC660ELB921M’s ring topology support ensures network redundancy. A US integrated power plant deployed 18 IC660ELB921M modules in a ring network connecting 18 RX3i racks (controlling turbines, boilers, and generators): when a cable between two modules failed, the network recovered within 250ms, and all control loops continued operating without interruption. This reduced unplanned downtime from 4 hours (with single-port modules) to 0 minutes, avoiding $200,000 in lost power generation revenue per incident.
Multi-Protocol Compatibility for Interoperability
Supporting Modbus TCP, Ethernet/IP, and DNP3.0 protocols, the IC660ELB921M ensures seamless integration with diverse industrial devices. A Chinese smart factory used 8 IC660ELB921M modules to connect its RX3i PLC system with third-party equipment: 4 modules acted as Modbus TCP clients to collect data from Siemens S7-1200 PLCs (controlling conveyors), 2 modules served as Ethernet/IP adapters to communicate with Allen-Bradley VFDs, and 2 modules ran DNP3.0 over IP to send data to the plant’s SCADA system. This compatibility avoided the need for expensive protocol converters (which would have cost $30,000), reducing integration costs by 60%.
Advanced Security and Remote Diagnostics
Equipped with 802.1X authentication and a built-in web server, the IC660ELB921M enhances network security and simplifies maintenance. A Middle Eastern oil refinery deployed 10 IC660ELB921M modules in its hazardous area RX3i systems: 802.1X authentication prevented unauthorized access to the control network, and the web server allowed engineers to remotely configure IP addresses and run ping tests. During a recent maintenance cycle, engineers used the built-in packet capture tool to diagnose a communication issue with a DNP3.0 SCADA link—reducing troubleshooting time by 80% compared to modules without remote diagnostics.
