1U RACK PC

Relio R4 - Intel 3rd Gen. Core i7/i3/Atom 19" 1U Rack-mount PC with up to 16GB DDR3 memory, Mini PCI-Express and two SeaRAQ I/O expansion slots

Wide Voltage

These devices and systems have been designed to accept a wide voltage DC power input. This feature is desirable in the industrial market where a fixed voltage level or mains AC power cannot be guaranteed.

Fanless

These products use heatsink, heatpipe and extrusion technology to dissipate the heat generated by the system rather than using traditional fans thus improving system reliability and longevity.

Linux

This product supports Linux based kernels. See product datasheet and manual for a list of compatible Linux kernels and distributions (for development and pre-sales support please contact our technical sales team).

RoHS

This product fully adheres to the Restriction of Hazardous Substances Directive 2002/95/EC, RoHS for short.  The directive covers the restriction of use of certain hazardous substances in electrical and electronic equipment and was adopted in February 2003 by the European Union.

CE

CE is a mandatory standard for products on the market in the European Economic Area. By CE marking a product, the manufacturer ensures that the item meets the essential safety requirements set out in the applicable CE directive.

FCC Approved

The Federal Communications Commission (FCC) is an independent agency of the United States government that sets standards and governs the testing of conducted and radiated emissions such as EMI.

UL

Underwriters Laboratories (UL) is an independent product safety certification organisation based in the United States. UL develops standards for products, materials, components, assemblies, tool and equipment, mainly dealing with product safety.

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 an operating temperature range of 0°C to +50°C.

A wealth of standard I/O features include dual Gigabit Ethernet, five USB2.0 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.
