Introduction
The Relio R3 is a solid-state 3U rackmount computer designed for applications requiring high reliability,
maximum I/O expansion, scalable processing, and a long product lifecycle. The R3’s fanless and nearly
cable-less structure ensures extensive durability for long-term usage. The R3 differs from traditional
industrial computer systems in that it is 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. This manual will focus on the higher level features of the R3 computer system. More
detailed information (for example, connector pin outs) can be found in the 12000 COM Express carrier
board manual.
The R3 is compatible with Basic and Compact form factor Type 6 pin out 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 custom 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.
Sealevel COM Express carrier boards leverage the company’s years as a leader in I/O and communication
products to provide carrier board and full system solutions in the fastest time possible. Common I/O
features include serial, analog and digital I/O. Sealevel’s extensive library of proven I/O circuits can be
included as required to meet the specific I/O count, voltage ranges and connector types.

Optional Items
Depending upon your application, you are likely to find one or more of the following items useful with the
R3. All items can be purchased from our website (www.sealevel.com)or by calling our sales team at (864)
843-4343.
DB9 Female to DB9 Male Extension Cable, 72” Length (Item# CA127)
The CA127 is a standard DB9F to DB9M serial extension
cable. Extend a DB9 cable or locate a piece of hardware
where it is needed with this six-foot (72-inch) cable. The
connectors are pinned one-to-one,
so the cable is
compatible with any device or cable with DB9 connectors.
The cable is fully shielded against interference and the
connectors are molded to provide strain relief. Dual metal
thumbscrews secure the cable connections and prevent
accidental disconnection.
9 Female to DB25 Male Standard RS-232 Modem Cable, 72” Length
(Item# CA177)
The CA177 is a standard AT-style RS-232 modem cable
with a DB9 female connector on one end and a DB25 male
connector on the other end. Simply connect the DB9
female connector to the DB9 serial port on the R3, and
then connect the DB25 male connector to your RS232
serial modem or other compatible RS-232 serial device.
The six foot cable is fully shielded with dual thumbscrews
at each connector. The molded conne
ctors integrate
strain relief to prevent damage to the cable or connectors.
All DB9 modem control signals are implemented, and the
cable is pinned to EIA-232 standards.
Terminal Blocks
DB9 Female to 9 Screw Terminal Block (Item# TB05)
The TB05 terminal block breaks out a DB9 connector to 9
screw terminals to simplify field wiring of serial
connections. It is ideal for RS-422 and RS-485 networks,
yet it will work with any DB9 serial connection, including
RS-232. The TB05 includes holes for board
or panel
mounting. The TB05 is designed to connect directly to the
R3 DB9 serial ports or any cable with a DB9M connector.
DB9 Female to 5 Screw Terminal Block (RS-485) (Item# TB34)
The TB34 terminal block adapter offers a simple solution
for connecting RS485 field wiring to the R3’s serial port
3. The terminal block is compatible with 2-wire and 4wire
RS
485 networks. A pair of thumbscrews secures the
adapter to the DB9 male connector and prevents
accidental disconnection.

Patch Cable (RJ45) with blue jacket.
06 Channel Isolated RTD Analog Inputs (Part# 6511)
The SeaRAQ 6511 analog expansion board is specifically
designed to interface RTDs (Resistance Temperature
Detectors). RTDs offer a wide temperature measurement
range, good accuracy, repeatability, and long-term stability
well-suited to industrial applications.
6 Channel Isolated Thermocouple Inputs (Part# 6512)
The SeaRAQ 6512 analog expansion board is specifically
designed to interface inexpensive thermocouples. To
simplify temperature calibration in the field, cold junction
compensation is provided on the board.
16 Channel Isolated Digital Inputs (3-30 VDC) (Part# 8510)
The SeaRAQ 8510 expansion board adds 16 channels of
isolated digital inputs designed for 3-30 VDC. The inputs
are compatible with TTL signal levels.
16 Channel Isolated AC Digital Inputs (0-132 VAC) (Part# 8511)
The SeaRAQ 8511 expansion board adds 16 channels of
isolated digital inputs rated for 0-132 VAC.
16 Channel Isolated Form Relay Outputs (Part# 8520)
The SeaRAQ 8520 expansion board adds 16 isolated relay
outputs rated for 5-250 VAC and 5-30 VDC. The Form A
relays are organized into four banks of four relays, with
each bank sharing a common. The relays support a
maximum current load of 2A per relay (4A maximum per
bank). The SPST relays are normally open and close when
energized.

06 Channel Isolated Relay Outputs (Part# 8521)
The SeaRAQ 8521 expansion board adds 8 isolated relay
outputs rated for 5-250 VAC and 5-30 VDC. The Form A
relays each have a discrete common and support a
maximum 4A current load. The SPST relays are normally
open and close when energized.
08 Channel-to-Channel Isolated Analog Inputs (Part# 6510)
The SeaRAQ™ 6510 supports two input analog voltage
ranges 0-5VDC and 0-10 VDC as well as 0-20mA input on
each of its 8 isolated channels.
08 Channel-to-Channel Isolated Analog Outputs (Part# 6520)
The SeaRAQ™ 6520 is an 8 channel-to-channel isolated 4-
20 mA loop-powered analog output card. Input voltage
range is 5.5V to 52V. User data is scaled so that 4.0 mA
output corresponds to a raw digital count of 0 and 20.0
mA corresponds to a count of 65535 (full 16-bit
resolution). When a fault is detected (DAC
communications, Vloop tolerance, etc.) the output is
automatically driven to the alarm current of 3.2 mA.

The R3 computer system is a fan-less, solid state computer that relies on thermal conduction to move heat
from internal components to the outside of the enclosure. Airflow around the computer assists with this
heat removal process. It is optimal to mount the computer in an area that has either natural or forced airflow
to constantly remove heat from the enclosure.
1Operating temperature is dependent on particular model. See the Operating Temperature
Range section for model capabilities.
