Introduction
Overview
The Relio™ R1 Rugged Industrial Computer is an exceptionally rugged embedded computer for operating
in harsh environments. The R1 Rugged’s fanless and nearly cableless structure ensures durability over long-
term use. Built using the PICMG COM Express architecture, Sealevel has partnered with the leading COM
Express module manufacturers to ensure our customers benefit from the best in the industry.
The R1 Rugged is the latest addition to the industry-leading Relio embedded computer line. The R1 Rugged
incorporates the newest generation of industrial processors and a modernized video interface. With
versatile communication options for CAN, Wi-Fi, and RS-232/485, the R1 Rugged features (2) locking USB
3.1 ports, (2) locking USB 2.0 ports, (2) Gigabit Ethernet ports, and an extreme, wide operating temperature
range of up to -40°C to +71°C.
The R1 Rugged has an extreme rugged, anodized aluminum enclosure combined with intentional thermal
management for unmitigated performance under environmental extremes. The fanless, solid-state design,
combined with locking SeaLATCH USB connectors, ensures shock and vibration tolerance as well as long-
term reliability.
With a robust and flexible I/O mix, this rugged industrial computer is capable of managing a variety of data
inputs to interface with legacy systems and the most advanced peripherals. The embedded computer’s
COM Express architecture gives manufacturers a technology migration path to easily change, and upgrade,
the CPU functionality without a complete system redesign or replacement.
Inside the R1 Rugged, a CFAST SATA II card slot provides solid-state storage ranging from 64GB to 256GB.
The R1 Rugged is compatible with Windows 10 IoT Enterprise, Windows 11 Pro, Linux RHEL 8 (or later), and
Linux Ubuntu 21 (or later). The system is also Windows 11 IoT-ready to provide maximum flexibility for
evolving, customer-specific software applications. Sealevel’s SeaCOM hardware driver is included to
support system I/O. Serial application code samples assist with custom application development and
complete support documentation expedites configuration.

COM Express Module/RAM Configuration Options
The R1 Rugged Industrial Computer is compatible with compact form factor Type 6 COM Express modules.
COM Express is a widely supported implementation of Computer on Module (COM) design. The COM
Express architecture reduces the complexity, cost and time required for computer system design by
combining the processing, memory, video, Ethernet and USB functionality in a small, highly integrated
module. COM Express modules install on a carrier board that provides the application specific I/O and
external connectors best suited for the system requirements.
Our COM Express carrier boards leverage Sealevel’s I/O and communication expertise, providing carrier
board and full system solutions as rapidly as possible.
The R1 I/O Rugged Industrial Computer is available in a variety of configurations, see the Sealevel website
for all configurations:
Relio™ R1 Rugged Industrial Computers
SATA CFAST Type I, II Memory
When power is removed from the R1 Rugged, the CFAST memory card inside can be replaced. To do this
remove all screws from the side faceplate. The existing card can then be pulled from the port and a new
card inserted. Reinstall the faceplate before connecting power to the device.
