Sealevel Relio R1 Industrial Computer

The Sealevel Relio R1 compact rugged industrial computer is designed for applications that demand powerful processing capabilities, wide operating temperature range, and DIN Rail compatibility, while designed to exceed military specifications for shock & vibration.

Sealevel takes COM Express architecture to extremes with the Relio R1 industrial computer, featuring your choice of quad, dual and single-core Intel Atom® (Bay Trail) processor with up to 8 GB of DDR3L RAM, or powerful dual-core Intel Core i5-6300U (Skylake-U) processor with 8 GB of DDR4 RAM, in a virtually indestructible, DIN Rail compatible enclosure. The R1 is Sealevel’s most rugged computer to date, designed to exceed military specifications for shock and vibration.

The Sealevel Relio R1 achieves an impressive operating temperature range of -40°C to 71°C, while requiring low power consumption from your 18-36 VDC source. Standard features include two software-selectable serial ports, dual Gigabit Ethernet, four SeaLATCH™ locking USB ports, digital and analog video interfaces. The 802.11 b/g/n dual-band wireless network option enables convenient connectivity at data rates up to 300 Mbps. CAN bus 2.0b and GPS options are also available.

Inside the R1, a CFast SATA II card slot provides solid-state storage that can be preloaded with 32-bit or 64-bit versions of Microsoft Windows or Linux operating systems. The optional, rugged DIN Rail bracket allows secure mounting to 35mm DIN Rail located inside panels, vehicles or even heavy equipment and drilling rigs. The optional VESA bracket supports 75mm or 100mm installation to industrial and commercial displays, and also doubles as a wall or table mount. The system is perfect for harsh industrial environments including military, oil & gas, transportation, energy, and process control applications.

The COM Express design allows easy technology migration as processor technology evolves. As a result, the COM module can be upgraded to increase performance over the life of the application.

Note: Optional Wi-Fi only approved for US & Canada.
