AR530 Industrial Switching Router

The AR530 industrial switching routers are industrial gateways that are designed to work in harsh environments. They integrate routing, switching, security, and Advanced Metering Infrastructure (AMI) functions and provide a variety of extensions.

Compared with enterprise routers, industrial routers are more applicable to harsh industrial environments because their components are more strictly selected. The AR530 uses a wider temperature range and a fan-less design and provides Ingress Protection 51 (IP51). With these key technologies, the AR530 is high- and low-temperature resistant, dustproof, waterproof, and can resist electro-magnetic interference. The AR530 uses a modular design and integrates various types of interfaces, such as FE, SFP, and RS485. It can connect to various types of meters and communicate with devices in neighboring sites, thereby meeting different scenario requirements.

The AR530 provides AMI centralized meter reading services. It can automatically collect meter and status data, analyze and store data in a centralized manner, and send data to the front end processor and Meter Data Management System (MDMS). The AR530 provides uplink, downlink, and local networking, thereby meeting the requirements of the Internet of Things in the electricity industry.

Applications Integrated in One Device, Reducing Total Cost of Operation

  • Integrates the routing and data collection functions and provides various types of interfaces, such as FE, GE, and RS485.
  • Supports switching and Smart Ethernet Protection (SEP), implementing millisecond-level protection switch-over.
  • Has a built-in, zone-based firewall, ensuring production security.

Better Experience with Zero Service Interruption

  • Complies with substation environment standard IEC61850-3/IEEE1613.
  • Provides IP51 and is dustproof and waterproof.
  • Uses a fan-less design and works at temperatures from –40°C to +70°C.
  • Works normally in environments that have strong electro-magnetic interference.

Co-operation Platform and Enterprise-Class Applications

  • Open protocol standards: Complies with IEC62056 (DLMS/COSEM) and inter-works easily with other devices.
  • Flexible configuration and management: Allows you to flexibly configure data collection services to meet customized customer requirements.

AR530s as Industrial Routers

The AR530 industrial switching routers function as industrial routers and provide flexible WAN access modes for remote network connections. A single AR530 can provide FE, SFP, and RS485 interfaces to meet networking requirements in different industries. This helps save deployment and maintenance costs and maximizes customers' ROI.

AR530s as Industrial Switches

The AR530 supports SEP and can be rapidly and easily deployed on a complex network. STP, RSTP, and MSTP can run the network simultaneously. The AR530 has a convergence time of less than 50 ms, and when a fault occurs, it is easy to locate. The AR530 provides a reliable system running environment, which improves network maintainability.

AR530s as Industrial VPN Routers

The AR530 supports various secure access functions to secure data transmission between terminals and master stations. Secure tunnels such as GRE VPN, IPSec VPN, DSVPN, SSL VPN, and L2TP VPN are established between AR530s and master stations to implement secure data access and transmission.

AR530s as Gateways on the Internet of Things

As industrial gateways, AR530s integrate the functionality of both data concentrators and routers. AR530s can be used extensively throughout the electricity AMI solution, energy efficiency management solution, and Supervisory Control and Data Acquisition (SCADA) solution, thereby facilitating installation and commissioning, and reducing investments. For example, in the electricity AMI solution, AR530s connect to terminals through standard Ethernet interfaces and RS485 industrial interfaces. AR530s collect and store meter data and upload data to the management platform.
