The Relio R4 is a fanless, solid-state 1U rackmount computer with no internal cables. The system is ideal for rugged applications that demand high reliability, I/O expansion, scalable processing and a long product life cycle.

The R4 builds upon the advantages of the COM Express architecture and features your choice of Intel dual-core processor (Atom N2800 1.8GHz; Core i3 1.6GHz; Core i7 1.7GHz) and up to 16GB RAM. The rackmount system requires low power consumption while operating fanless over a wide operating temperature range of 0-50C. A wealth of standard I/O features include dual Gigabit Ethernet, five USB 2.0 ports, three serial ports, DisplayPort video and audio interfaces. The R4 operates with no moving parts or internal cables, eliminating the most common causes of failure.

Featuring two SeaRAQ™ I/O expansion slots, the Relio R4 offers extra expansion capabilities and supports a variety of real-world analog I/O configurations such as A/D inputs, 4-20mA outputs, 0-20mA inputs, thermocouples and RTD inputs. Optically isolated inputs, relay outputs and additional serial interfaces are also available.

The Relio R4 operates from your choice of 2.5" SATA solid-state disk (SSD) that can be integrated and preloaded with 32-bit or 64-bit versions of Microsoft Windows or Linux operating systems. Operating from solid-state disk, the system is perfect for industrial and commercial rackmount environments including process control, test & measurement and HMI applications.

Extended temperature range and other options are available. If you have application specific requirements, call today to discuss a Sealevel custom COM Express solution.
