Introduction
The DIO-16.LPCI provides 8 optically isolated inputs and 8 reed relay SPST (single pole-single throw)
outputs. The inputs protect the PC and other sensitive equipment from spikes and ground loop current that
can be generated in industrial environments, while 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 will close when energized.
The board meets the requirements for the MD1 "Low Profile" specification as defined by the PCISIG in the
PCI 2.2 Specifications Low Profile Addendum. The DIO-16.LPCI also features Universal Bus (3.3 and 5.0V)
operation.
The DIO-16.LPCI is designed to be used with a variety of Operating Systems including Windows, Linux, and
DOS. The SeaI/O API (Application Programming Interface) provides a variety of useful high-level function
calls implemented as a Windows dynamic link library (.DLL) and as a Linux static library (.a). In addition to
the API, SeaI/O includes a device driver, sample code, and utilities to simplify software development.
Features
•Eight optically isolated inputs optimized for +5V
•Eight Reed relay outputs (SPST)
•Highly reliable 10VA Reed relays
•MD1 Low Profile and Universal Bus (3.3V and 5V) compatible
•Power (+5V and +12V) and ground provided on connector
•SeaI/O Classic software supports Windows and Linux Operating Systems

Optional Items
Depending upon your application, you are likely to find one or more of the following items useful for
interfacing the DIO-16.LPCI to real-world signals. All items can be purchased from our website
(http://www.sealevel.com) or by calling [phone].
Cables
DB44 Male to DB44 Female, 72” Extension Cable (Item# CA185)
The CA185 is a standard DB44M to DB44F extension cable.
Extend a DB44 cable or locate a piece of hardware where it is
needed with this six foot (72”) cable. The connectors are
pinned one-to-one, so the cable is compatible with any device
or cable with DB44 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.
DB44 Male to BD37 Male, 72” Cable (Item# CA206)
DB44 Male to DB37 Male Cable, 72 in Length - for 8012. The
CA206 is useful for interfacing the DB44 connector on the
8012 to the DB37 connector on the TB02 terminal block.

Terminal Blocks
Terminal Block –DB37 Male and DB37 Female to 27 Screw Terminals (Item# TB02)
CABLE & TERMINAL BLOCK KIT
The TB02 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.
Terminal Block Kit –DB37 Male and DB37 Female to 27 Screw Terminals
(Item# TB02-KT)
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 Kit –TB02 + CA206 Cable (Item# KT111)
CABLE & TERMINAL BLOCK KIT
The TB02 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.
Reference Book
The Digital I/O Handbook –A Practical Guide to Industrial Input and Output
Applications (Item# REF101)
Renowned technical author Jon Titus and president and CEO
of Sealevel Systems, Tom O'Hanlan, clearly explain real-world
