DIO-16.LPCI User Manual

Introduction

The DIO-16.LPCI provides 8 optically isolated inputs and 8 reed relay 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 ships with a Low Profile PCI bracket that will only work in a Low
Profile PCI slot. If you need a standard size PCI bracket, please order part number
8012S. 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 98/NT/ME/2000/XP, Linux and DOS. The SeaI/O API
(Application Programmer Interface) included on CD with the DIO-16.LPCI 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. In addition to the API,
SeaI/O includes sample code and utilities to simplify software development.

DIO-16.LPCI User Manual

Programming the DIO-16.LPCI

Sealevel’s SeaI/O software is provided to assist in the development of reliable
applications for the Sealevel Systems family of digital I/O adapters. Included on the
SeaI/O CD are driver functions for use in accessing the I/O as well as helpful
samples and utilities.

Programming for Windows

The SeaI/O API (Application Programmer Interface) provides a variety of useful
high-level function calls implemented in a Windows dynamic link library (DLL).
The API is defined in the help file (Start/Programs/SeaIO/SeaIO Help) under
“Application Programmers Interface”. This help file also includes detailed
information dealing with installation / removal of the software and information
about latency, logic states, and device configuration.

For C language programmers we recommend using the API to access the DIO-

16.LPCI. If you are programming in Visual Basic, using the ActiveX control
included with SeaI/O is advised.

Samples and Utilities

A variety of sample programs and utilities (both executable and source code) are
included with SeaI/O. Further documentation on these samples can be found by
selecting “Start/Programs/SeaIO/Sample Application Description”. Information
about where the files are physically stored on your disk is also included in this same
file.

Programming for Linux

SeaI/O for Linux consists of two major parts: a kernel module and a library. The
kernel module is a simple IO pass-through device, allowing the library to handle the
more sophisticated functions provided to SeaI/O users. It is provided in a ‘tarball’
format and can easily be compiled and included in the kernel build.

Digital I/O Interface

The DIO-16.LPCI provides two parallel input/output (I/O) ports. The ports are
organized as ports A and C. Port A is an input port interfaced to optically-isolated
inputs, while port C is the reed relay output port. Assuming an I/O address of 300
Hex the following table shows the Port Addresses.

Base Address Hex Decimal Mode

Port A Address 300 768 Optically Isolated Input Port
Port C Address 302 770 Reed Relay Output Port

DIO-16.LPCI User Manual

Input Ports

Port A is an 8 bit input port connected to optically isolated input sensors. Each
sensor can be used to interface a voltage input and then sense whether the voltage is
on or off. Each sensor is isolated (with respect to a common ground) from every
other sensor, and is also isolated with respect to the host PC ground. This means that
signals such as low-level AC line voltage, motor servo voltage, and control relay
signals can be ‘sensed’, or read by the PC, without the risk of damage due to ground
loops or ground faults.

Each sensor input pair has a current limiting resistor that is used to limit the input
current to the opto-isolator. The opto-isolator has two ‘back-to-back’ diodes
internally. This allows AC or DC signals to be sensed, regardless of polarity. When
the applied voltage is high enough to cause the LED in the opto-isolator to turn-on,
the output of the opto-isolator goes low (0 volts) and the signal is read as a low logic
level (binary 0) by the PC. When the input signal is too low to turn on the opto­isolator, the output goes high and the port bit is read by the PC as a high logic level
(binary 1).

The input impedance of each isolated input is approximately 560 ohms
(factory default). The opto-isolator requires approximately 3 mA to turn on. The
maximum input current is 60 mA. Two things to consider when selecting the input
resistor. The first is turn on voltage for the circuit to sense, and second is the
maximum input voltage. Maximum input voltage must not provide too much power
to the input resistor, and must also not overdrive the opto-isolator input current
specification. The following formulas apply:

Turn on Voltage = diode drop + (turn on current) x ( resistance)
Or: 1.1 + (.003) x R
Maximum voltage = square root of (.25 (resistor value))
The following table shows four common input resistors and the ranges associated

with each.

Input Resistor

(Ohms)

Value Turn-On

(Volts)

Max Input Range

(Volts)

Max Current

(mA)
220 1.76 7 27
560 2.8 12 20

1K 4.1 16 15

2.2K 7.7 24 10

Increasing the input resistor accordingly can increase the maximum input voltage.
Because socketed DIP resistor networks are utilized, they can easily be replaced
with a different value. Sealevel, if necessary can do this. The input circuits are not
intended for monitoring 120-volt AC circuits. In addition to being too high a voltage
for the circuits, it is dangerous to have that high a voltage on the card.

Direct Hardware Control

In systems where the users program has direct access to the hardware (DOS) the
tables that follow give the mapping and functions that the DIO-16.LPCI provides.

Function Available Port Address Hex Port Type

RD A Base + 0 Optically Isolated Input Port

RD/WR C Base + 2 Reed Relay Output Port

RD = Read, RD/WR = Read or Write

Reading the Inputs

The inputs are active Low. If no voltage is applied across one of the differential
inputs it returns a one on that bit. If an AC or DC voltage is applied it returns a zero
on that bit.

Reading the Outputs

The relay ports return the ones complement of the value that is currently being used
to drive the relays. When using the API the actual value is returned not the
complement of the value.

Writing the Outputs

The output ports are the only ports that can be written. The relays on a standard
DIO-16.LPCI are normally open. To close a relay a one must be written to the
appropriate bit.
