The 8003e is shipped with the following items. If any of these items are missing or damaged, please
contact Sealevel for replacement.
8003e -REL-16.PCIe Digital I/O Adapter
DB78 Male to DB37 Male cable (Item# CA490)
Sealevel Software CD – SeaI/O Classic Software and User Manual
Warning - The highest level of importance used to stress a condition where damage could result to
the product or the user could suffer serious injury.
Important– The middle level of importance used to highlight information that might not seem
obvious or a situation that could cause the product to fail.
Note – The lowest level of importance used to provide background information, additional tips, or
other non-critical facts that will not affect the use of the product.
The REL-16.PCIe provides16 reed relay outputs. The outputs provide high quality, long life, low current (10
Watt maximum), dry contact switch closures. Reed relays are well suited for low current applications. The
relays are normally open, and close when energized.
The SeaI/O Classic software drivers and utilities are included on the CD and make installation and operation
easy using Windows 7, Vista, and XP operating systems. The SeaI/O API (Application Programmer Interface)
provides a variety of useful high-level function calls implemented as a Windows dynamic link library (DLL)
and as a Linux kernel module and library. SeaI/O also includes sample code and utilities to simplify
software development.
PCI Express X1 compliant
16 Reed relay outputs (SPST)
Highly reliable 10VA Reed relays
Power (+5V and +12V) and ground provided on DB78 board connector
Includes 72” cable with DB78 Male connector to DB37 Maleconnectors (Item# CA490)
SeaI/O Classic software supports Windows 7, Vista, and XP operating systems
Software support for Linux available
DB37 Male to DB37 Female Extension Cable (Item# CA112)
This cable provides a 6’ extension to the CA490. It has
one DB37 Male connector and one DB37 Female
connector.
DB78 Male to DB78 Female Extension Cable (Item# CA233)
This cable provides a 6’ extension to the DB78 board
connector on the 8006e. It has one DB78 Male connector
and one DB78 Female connector.
DB78 Male to (1) DB37 Male (Output) Cable (Item# CA490)
The CA490 is a 72 inch cable with a DB78 male
connector that is compatible with the board connector
on the 8003e. The other end of the cable terminates in a
DB37 male connector for digital outputs. This is the
replacement for the cable that ships with the 8003e PCI
Express digital I/O interface.
Depending upon your application, you are likely to find one or more of the following items useful with the
8003e. All items can be purchased from our website (www.sealevel.com) by calling our sales team at (864)
843-4343.
The TB02-KT terminal block can be used to break out
serial and digital DB37 connectors to screw terminals for
easy field wiring. The terminal block was designed with
both DB37 male and female connectors, therefore; it can
be used with any DB37 board regardless of the board's
port gender.
The TB02-KT ships with a RoHS compliant TB02 terminal
block, a 6 piece of slotted Snap Track, and two DIN-rail
mounting clips.
Terminal Block KT101 includes the TB02 and CA112
(DB37 M/F cable). This cable kit can be used with both
37 pin Digital I/O and Serial I/O products.
The Digital I/O Handbook - A Practical Guide to Industrial Input and Output
Applications (Item# REF101)
Renowned technical author Jon Titus and the President
and CEO of Sealevel Systems, Tom O'Hanlan, clearly
explain real-world digital input/output implementation
from both a hardware and software perspective. Whether
you are a practicing engineer or a student, The Digital
I/O Handbook will provide helpful insight you will use
again and again.
2 I/O ports with each having 8 SPST relays
DB-37 Male connector for relay outputs
Highly reliable 10 VA reed relays
Multiple adapters can reside in same computer
