November 11, 2015 - Westermo releases MRD-305-DIN 3G router for remote access across mobile networks. It supports many mobile standards including GSM, GPRS, 3G, EDGE, HSDPA and HSUPA, and is compatible with any type of SIM card, such as static IP SIM, M2M SIM, or an off-the-shelf SIM..
This device provides access to remotely located machines, SCADA systems, PLCs and HMIs using a wide variety of communication methods, eliminating the need for time-consuming site visits and providing a network infrastructure suitable for today’s `always-on’ society.
The MRD-305-DIN is suitable for a broad range of M2M applications ranging from securely connecting simple devices to each other or a server via a virtual private network, to simply providing a gateway to the internet for more intelligent systems. It features a connection manager that automatically, and without user-interaction, reconnects to the carrier network to ensure a constant connection to any remote asset.
The device has a power input range of between 10 and 36 VDC and an operating temperature range of -40C to 70C. A built-in two-port Ethernet switch meets the majority of typical applications such as connecting a PLC and accompanying HMI, and enables easy integration.
The unit offers network protection from malicious eavesdroppers via encrypted communication tunnels (VPN), and features a simple, yet powerful, packet inspection firewall to prevent unauthorised access. Configuring the unit is very easy with the built-in web-interface. The device can also provide both management and monitoring via SMS. For example an SMS could be sent to start a VPN.
