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.
SATA CFast Type I, II Memory Card Port

Power Input
The system is designed to operate from 18VDC up to 36VDC. The current draw varies across this range;
it is heavily dependent on the COM Express module, peripheral devices and installed software. The main
power input is via a 2-pos 5.08mm pluggable, locking connector (SL#104456). The power source must
be appropriately listed ITE Power Supply Limited Power Source, or LPS, suitable for the maximum
ambient temperature at the installation.
18-36VDC Input Power
If the computer must be located in an environment outside of 0°C to +40°C, ensure the power
source that you will be using can supply the power listed over the operational temperature range.

Hardware Installation
For full installation instructions, please refer to the Installation Guide provided with your R1 Rugged. If you
do not have the installation guide readily available, contact our sales team at [e-mail]. They
can also provide you with 3D model images, and compliance certifications for the R1 Rugged.
Installation Considerations
The R1 Rugged can operate without airflow at 50°C as long as the steady-state CPU usage does not
exceed 50%. If CPU usage is sustained at a workload greater than 50%, the CPU will throttle itself back to
keep its internal temperature in a safe range.
If the application environment requires the computer to operate at 50°C with steady state CPU usage
greater than 50%, some additional cooling must be used to ensure safe operation of the electronics.
The R1Rugged Industrial Computer system is a fanless, solid state computer that relies on thermal
conduction to move heat from internal components to the outside of the enclosure. The lid is designed as
a finned heat sink to increase overall surface area. Three main cooling methods can be used to optimize
removal of heat from the system.
1. Airflow
2. Thermal conduction through mounting
3. Computer orientation
Airflow over the lid provides the most effective heat removal of these three options. It is optimal to mount
the computer in an area that has either natural or forced airflow to constantly remove heat from the
enclosure.
Mounting the computer to a large thermally conductive surface (such as an I-Beam, steel cabinet or other
large metal surface) allows heat to travel through the enclosure and be dissipated into the large structure.
•Only technically qualified personnel are permitted to install the equipment.
• Do not use the system with visible damage to any part of the unit or cable connection.
• Reduced Air Flow - Installation of the equipment should be such that the natural airflow around
the equipment is not compromised.
•Thermal derating – Installation of the system in vertical orientation is preferred for thermal
performance. Forced airflow or derating of the maximum operating temperature may need to be
considered in horizontal mounting orientation.
