Description

GE  760-P1-S1-LO-A10-G-T  digital relay module

Standard Communication Interfaces

Serial Communication Ports

• Front-panel RS232: Used for local configuration, debugging, and troubleshooting. Supports ModBus RTU protocol and can connect to portable programmers or PCs.
• Dual Rear RS485/RS422: Enables multi-device networking, allowing simultaneous connection to SCADA systems, substation automation systems, or other intelligent devices. Supports ModBus RTU and DNP3.0 Level 2 protocols.

Optional Ethernet Port

• Supports ModBus TCP/IP and DNP3.0 network protocols, providing high-speed data transmission (10/100Mbps auto-negotiation). Can be integrated into industrial Ethernet or enterprise-level networks.

Communication Protocol Support

• ModBus RTU: For serial communication, supporting standard function codes (read/write registers, coils, etc.), compatible with most industrial devices and software.
• ModBus TCP/IP: An Ethernet-based ModBus protocol enabling high-speed data exchange, suitable for remote monitoring and system integration.
• DNP3.0 Level 2: A communication protocol specifically designed for power systems, supporting event-triggered transmission, telemetry, telecontrol, and remote signaling functions, in compliance with power industry standards.

Data Transmission and Sharing

• Multi-port Concurrent Communication: Enables independent communication through RS232, RS485, and Ethernet ports simultaneously, allowing parallel local configuration and remote monitoring.
• Real-time Data Access: Supports real-time transmission of protection data (such as current, voltage, frequency), event records, fault waveforms, etc., facilitating remote analysis.
• Event-triggered Communication: Supports SOE (Sequence of Events) function with a timestamp accuracy of ≤1ms, capable of recording the exact time sequence of fault occurrences.

Network Integration Capabilities

• Industrial Network Compatibility: Supports redundant network configurations (such as dual Ethernet) to enhance communication reliability; can be integrated with other systems (such as DCS, PLC) via gateways.
• Network Security: Supports IP access control lists (ACL) and data encryption (optional), conforming to industrial network security standards.

Typical Application Scenarios

• Substation Automation: Communicates with RTU and SCADA systems to achieve remote monitoring and control.
• Distributed Energy Management: Integrates distributed power sources such as solar and wind energy, supporting bidirectional communication and coordinated control.
• Industrial 4.0 Integration: As an intelligent device, it connects to the Industrial Internet of Things (IIoT), providing a foundation for data collection and analysis.

Technical Parameters

• Baud Rate: Serial ports support adjustable 300~19200bps; Ethernet ports support 10/100Mbps auto-negotiation.
• Communication Distance: RS485 up to 1200 meters (standard); Ethernet up to 100 meters (UTP) or farther (fiber).
• Concurrent Connections: Ethernet port supports ≥4 concurrent connections to meet the needs of multi-system simultaneous access.
