Product Description

Product Description

The MRD-415 and MRD-455 industrial cellular routers make full use of the 2G, 3G, and 4G cellular networks to cost-effectively inter-connect systems, sites, and operators. Creating a solid foundation for smart automated systems, where machines can communicate with machines and service technicians can remotely monitor and maintain their valuable assets in any system.
Devices connected to the Internet require countermeasures against cybersecurity threats. The MRD series offers protection of transmissions from malicious eavesdroppers via encrypted communication tunnels (VPN) and features a simple, yet powerful, packet inspection firewall. Configuration of the device is done with a simple and intuitive web interface, management is also available with a basic CLI, and SMS messages can be used for controlling the device and receiving status updates.
The products feature a built-in 2-port Ethernet switch for connecting to any Ethernet device. For legacy support, there is also a built-in serial port that offers a simple modem replacement solution with the benefit of not having to reprogram or change any other component.
Features such as connection maintenance and network to network roaming ensure very high availability and a connection that is always available. This is crucial in mission-critical installations, where even the shortest downtime can prove very costly.
The MRD-415 comes in a very slim and robust casing which is ideal for wall mounting in small spaces, taking up very little space in a cabinet or similar. Connections come out on each end of the product, with antenna connectors on one side and Ethernet and serial interfaces on the other. It features a very low power consumption, making it the ideal choice for battery or solar-powered applications. Low power consumption combined with a clever power-saving feature allows the unit to run for a long time without the battery.
The MRD-455 comes in a very compact and robust casing ideal for mounting on DIN rails. All connections and LEDs are located on the front, making it ideal for installation in industrial cabinets and applications. To further strengthen the already high availability, they feature dual-SIM card slots, allowing the user to remove carrier dependency and swapping operators automatically if the primary run into trouble. It also features galvanic isolation between all interfaces (power supply, Ethernet, serial), to protect the product against electrical surges and overvoltage, which is common in many industrial applications.
