Wireless Router – MRD-350
Remote access removes boundaries, eliminates the need for time consuming site visits and provide a network infrastructure suitable for today’s “always-on” society. The Industrial Wireless Router MRD-350 industrial mobile broadband GPRS / EDGE / 3G router uses the Internet to cost effectively inter-connect systems, allowing HMI, PLCs, sensors etc to communicate with each other.
A compact design bundled with all interfaces and LEDs in the front make the unit extremely well suited for industrial applications. With isolation between the PSU and the Ethernet and serial ports the MRD-350 protects against issues caused by ground loops.
The dual SIM support in the device ensures that site connectivity is not dependent on a single carrier, should something happen the unit just switches to the other SIM.
Devices connected to the Internet require countermeasures towards cyber threats. The MRD-350 offers protection of transmissions from malicious eavesdroppers via encrypted communication tunnels (VPN), and features a simple, yet powerful, packet inspection firewall.
For solar powered applications energy efficiency is vital and the MRD-350 has a special low-power mode to only be fully powered when needed. The MRD-350 with its built-in serial port offers a simple modem replacement solution with the benefit of not having to reprogram or change any other component.
