Choose from a variety of options

The nROK 7251 series comes in two models: the nROK 7252-AC8S and nROK 7252 WI2-C8S. Both models feature your choice of Intel® Coffee Lake S/Refresh 9th or 8th Generation Core™ or Xeon® CPUs. The 7252-AC8S comes with 24V/36V DC input and four 15mm SSD bays, while the 7252-WI2-C8S includes 24~110VDC power isolation, protection against temporary voltage dips, and two 15mm SSD bays.

Watch and learn

Maintain safety and security while passengers board, disembark, and congregate in luggage zones, while performing tasks such as monitoring, recording, and big data analytics – all with video surveillance. Eight M12 X-coded 802.3 af/at PoE ports are available for PoE camera data transfer, ensuring reliability even in harsh environments. Ensure that your PoE railway computer has adequate storage with your choice of RAID 0/1/5/10 configured and hot-swap HDD/SDDs. With 4TB hard drives, for instance, you have enough space to store data from eight full HD cameras, running 24 hours per day, for approximately 66 days! You can also utilize a mSATA drive for OS and VMS software and an SD memory card for video clip backup.

Faster we go!

5G is all the buzz these days, which is why the 7252 series is 5G-ready! To increase bandwidth and reach higher speeds, three of five expansion slots are 5G/WWAN module-enabled, with another two available for Wi-Fi or LTE needs, creating your own cutting-edge communication hub. Each of the three 5G modules fit two SIM cards (for a total of six cards) to create network redundancy when one network is down. This also allows smarter selection: choose the connection with better latency and lower roaming costs. Having three independent WWANs online simultaneously also provides greater bandwidth.

Multimedia array, multiuse displays

To keep passengers entertained and connected, the other two expansion slots are available for Wi-Fi modules for easy access to multimedia infotainment and the Internet. The modules combine perfectly with the three independent video outputs (two HDMI and one VGA) so that passengers can view local entertainment, news, and weather reports, while drivers can monitor railway conditions via live cams. This also means the perfect business opportunity to display advertisements and commercials and collaborate with local tourist bureaus to present information about points of interest. In addition, the mobile communication hub’s serial port can link to LED displays to display journey information.

Thoughtful protection and construction

The work 7252-WI2-C8S features an isolation kit of 24 to 110 VDC input with supercars to safeguard your railway computer against sudden power surges, as well as uninterrupted protection for three seconds when encountering unexpected voltage dips. All models are constructed with higher-quality aluminum instead of iron and include a thermal dispatch system with copper pipe for more efficient thermal conductivity and uniform heat dissipation. Finally, the nROK 7252 is also environmentally friendly and ruggedized for suboptimal conditions, having been certified to both EN50155 and MIL-STD-810G standards. The 7252-WI2-C8S even features an anti-vibration design for data storage.
