ABB RET670 Transformer Protection Device

LON protocol: Connected through an optical LON interface, supporting the expansion of existing ABB station level LON networks, achieving peer-to-peer communication and collaborative work with other ABB IEDs, with a communication rate of 1.25 Mbit/s.

SPA/IEC 60870-5-103 protocol: Implemented through serial and LON communication modules (SLM), SPA protocol is suitable for simple substation automation systems, IEC 60870-5-103 supports multi vendor device integration, and communication rates can be configured (such as 9600, 19200 Bd, etc.).

DNP3.0 protocol: implemented through electrical RS485 or fiber optic Ethernet interface, supporting TCP/IP and EIA-485 communication, with event transmission, time synchronization, and disturbance reporting functions, suitable for communication with RTU, gateway, or HMI systems.

Redundant communication: Supports IEC 62439-3 parallel redundancy protocol (Edition 1 and Edition 2), achieves redundant station level communication through dual ports, and improves communication reliability.

Remote communication: It can exchange analog and switch signals with remote IEDs through Line Data Communication Module (LDCM), supports IEEE/ANSI C37.94 standard, suitable for short distance (<60 km) and medium distance (extended to<3 km through optical to electrical converters) communication, supports multiple fiber types (multimode, single-mode) and wavelengths (850 nm, 1310 nm).
