The Relio R3 is a solid-state 3U rack-mount computer designed for applications requiring high reliability, maximum I/O expansion, scalable processing and a long product life cycle.

Building on the advantages of COM Express architecture, the R3 features an Intel Atom N2800 1.8GHz dual-core processor with 4GB DDR3 memory. The fanless system features low power consumption and an operating temperature range of 0°C to +50°C. Standard features include 2x Gigabit Ethernet, 4x SeaLATCH locking USB2.0 ports, 3x serial ports, DisplayPort video and audio interfaces. The system includes a 7” LCD touch screen on the front panel for a convenient operator interface.

With a total of 18x SeaRAQ I/O expansion slots, the R3 offers unprecedented expansion capabilities supporting 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 system offers one PCI Express slot compatible with any half-length PCIe [x1] board.

The Relio R3 operates from your choice of 2.5" SATA solid-state disk (SSD) that can be integrated and preloaded with Microsoft Windows or Linux 32-bit operating systems. Operating from solid-state disk, the system is perfect for industrial and commercial rackmount environments including process control, test and measurement and HMI applications.
