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.

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.
