Description MRD-315
Remote access removes boundaries,
eliminates the need for time consuming site
visits and provides a network infrastructure
suitable for today’s “always-on” society. The
MRD-315 industrial mobile broadband
router uses the Internet to cost effectively
inter-connect systems, allowing HMI, PLCs,
sensors etc to communicate with each other.
A compact case design with DIN-rail
mounting clips and the wide power input
range between 10 to 60 VDC make the unit
well suited for industrial applications. Easy
integration with other devices is achieved
using the built-in two port Ethernet switch and the RS-232 D-sub.
The stability of mobile connections can be affected by various different parameters and in order to
ensure constant connectivity the MRD-series features a connection manager.
The MRD-315 offers network protection 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-315 has a special low-power
mode to only be fully powered when needed. The built-in serial port offers a simple modem
replacement solution with the benefit of not having to reprogram or change legacy components
during an upgrade.

* 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.
