The Relio R4520 is a compact, 1U rackmount industrial computer that offers unprecedented expansion capabilities using popular SeaI/O data acquisition modules. The system can be integrated with two SeaI/O modules in the front and an additional two SeaI/O modules in the rear, which is perfect for I/O intensive applications. An optional CDRW drive can replace one SeaI/O module.The R4520 is powered by a 1.0GHz ULV Intel Celeron M processor and includes 512MB (1GB Max) of DDR memory. The front of the system offers a wealth of standard I/O features including a CompactFlash socket, dual 10/100BaseT Ethernet jacks, two USB 2.0 ports, four serial ports, keyboard and mouse ports. An analog video connection supports resolutions to 1600x1200 (UXGA).An optional 2.5 hard drive can be integrated and preloaded with Windows XP. For the ultimate reliability, a front-accessible CompactFlash socket can be used for Windows Embedded and Linux operating systems. The system includes an internal 65W AC/DC power supply and ships with a US power cord.SeaI/O modules are available in a variety of I/O configurations including serial, optically isolated inputs, Reed and Form C relay outputs, TTL interfaces compatible with industry standard solid-state relay racks, A/D and D/A. See the accessories section below for a listing of SeaI/O upgrade options.
