Description MRD-355
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 MRD-355 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-355 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-355 offers protection of transmissions from malicious
eavesdroppers via encrypted communication tunnels (VPN), and features a simple, yet powerful,
packet inspection firewall.
The MRD-355 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.

* For example purpose only. Hard to predict exact values since there are a lot of factors that affect the power
consumption, such as signal strength. Example measurement was carried out in-doors in a 25ºC room with
"normal" signal strength.
