Date: 08/29/2003

Sealevel Systems, Inc., known for reliable I/O solutions, has introduced the company?s first industrial computing platform, the Relio? Series. Intended for the OEM, Relio systems combine the reliability and design consistency of a PLC with the versatility of an industrial computer. Relio systems operate over a wide temperature range with no moving parts. Unreliable hard drives and fans are not needed. For cost-effective expansion, the system offers a scalable architecture using PC/104 modules to provide a variety of application-specific I/O options.

Relio systems are available with 650MHz or 400MHz ULV Mobile Celeron? processors and are packed with standard I/O including dual 10/100Base-T Ethernet, four RS-232/422/485 multi-interface serial ports, and four USB ports. All components of Relio systems are designed and maintained with strict attention to long-term availability, avoiding the obsolescence problems inherent with motherboard-based industrial computers.

Interface to a wide variety of real world devices is available using Sealevel?s robust PC/104 I/O family. Choose from multi-interface serial, optically isolated input, Reed relay and TTL output, A/D, D/A, and wireless Ethernet options. Each option is equipped with an I/O connector module that mounts into any of the three expansion positions in the enclosure back panel, allowing any combination of up to three expansion modules.

Windows? XP Embedded is a perfect operating system choice for Relio systems. Sealevel offers application assistance for efficiently transferring customer applications to the XP Embedded platform. Other supported embedded operating systems include Windows?, TimeSys Embedded Linux?, VxWorks?, and QNX?.

Relio systems are 2U rackmount compatible and operate from an external 5Vdc power source. The 400Mhz Relio is available immediately from stock and is priced at $1495 in low volume quantities. OEM / volume pricing is available.
