To meet the growing demand for secure, flexible and reliable remote access for industrial network connectivity for its clients, Referro Systems has added Rockwell Automation’s Stratix 4300 to its inventory of products. “We are excited to bring the Stratix 4300 remote access router to our customers,” says Referro MD, Adrian van Wyk. “This, we believe, is the next generation of industrial connectivity as it combines flexibility, security and ease of use. At a mine site, for example, a variety of machines and systems require remote access connectivity to ensure efficient, safe and modern operations. These systems enable operations to enhance operational efficiency and reduce downtime.”
He adds that the network connectivity further enables operators to manage assets and machinery from remote locations, reducing personnel exposure to potentially hazardous environments and fast-tracking remediation. The Stratix 4300 offers a comprehensive platform that supports a wide range of network interfaces, including wired LAN and WAN connections, Wi-Fi and LTE cellular options. “This versatility enables users to tailor their connectivity approach to the specific demands of their sites and applications,” he says, adding that this could be either through leveraging high-speed gigabit Ethernet ports for fixed installations or using wireless technologies to overcome infrastructure limitations.

From wired-only models to wireless-enabled versions that provide 2,4 GHz and
5 GHz Wi-Fi bands or LTE cellular connectivity, customers can select the device configuration suited to their performance or security needs. “Security is top of mind for all our customers. The Stratix 4300 remote access router is a dedicated platform for FactoryTalk remote access manager software. This combination provides support for installation, programming updates, and on-demand troubleshooting and maintenance, enabling secure VPN connectivity that safeguards sensitive automation assets from unauthorised access,” Van Wyk continues. “This integration further facilitates remote programming, troubleshooting and maintenance, while supporting centralised management, user authentication and comprehensive audit logging. These features are critical to maintaining compliance in modern industrial environments.”
