IES-5301 Gateway
The IES-5301 is a front-end access device designed for substation applications. It serves as the core node for unified data acquisition, protocol conversion, and communication management within the substation monitoring system, enabling reliable interconnection between various intelligent electronic devices (IEDs) in the station and the upper-level monitoring system. The IES-5301 supports several protocols, such as IEC 61850,IEC 60870-5-101/104, IEC 60870-5-103, Modbus and DNP3.0. Data can be transmitted to and received from analog channel, digital channel or network connected to CC, DCS or other system. The direct transmission mode and the device independent avoid any interaction or influence with the substation SCADA (Supervisory Control And Data Acquisition) system.

Product Highlights
Multiple Protocols
The IES-5301 gateway supports mainstream protocols (IEC 61850, IEC 60870-5-101/104, Modbus, DNP3), unifies access to various substation devices, aggregates multi-vendor multi-protocol data, standardizes it via protocol conversion, and uploads it to the station-level monitoring system.
Multiple Languages
The device management interface and logs support multi-language switching, facilitating localized operation by foreign maintenance personnel.
Engineered for Broad Deployment
Adopts a wide temperature and voltage design to adapt to the varying requirements of different overseas regions.
Flexible Networking
Supports multiple network topologies including star, ring, and bus, accommodating the networking requirements of substations of varying scales.
