Introduction

Overview
The DIO-32.PCIe digital I/O interface provides 16 optically isolated inputs and 16 reed relay SPST (single pole-single throw) outputs. The inputs protect the PC and other sensitive equipment from spikes and ground loop currents that can be generated in industrial environments, while the outputs provide high quality, long life, low current (10 Watt maximum), and dry contact switch closures. Reed relays are well-suited for low-current applications. The relays are normally open, and close when energized.
The DIO-32.PCIe is designed to be used with Windows Operating Systems. The SeaI/O API (Application Programming Interface) included in Sealevel’s software provides a variety of useful high-level function calls implemented as a Windows dynamic link library (.DLL). In addition to the API, SeaI/O includes a device driver, sample code, and utilities to simplify software development.
8004ec vs 8004Hec
The 8004ec features surface mount input resistors that give the optically isolated inputs their +3v to +30v input range.
The 8004Hec offers more flexibility as the 8004Hec features socketed DIP resistors which allow the user to configure an input range (up to +36V) based on what socket resistors the user selects. The chosen socketed resistor value will determine what the turn-on voltage will be for the optically isolated inputs under the 8004Hec Socketed Input Resistor Selection Table.

Programming the DIO-32.PCIe
Sealevel’s SeaI/O Classic software is provided to assist in the development of reliable applications for the Sealevel Systems family of PCI and PCI Express digital I/O adapters. Included in Sealevel’s software 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 the 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 SeaLINK DIO-32.PCI. If you are programming in Visual Basic, using the ActiveX control included with SeaI/O is advised.
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.
Samples and Utilities
A variety of sample programs and utilities (both executable and source code) are included with SeaI/O. On Windows, the samples can be found by navigating to “Start->Programs->SeaIO->Samples.” On Linux, the samples are contained in the ‘examples’ folder within the downloaded tarball.

Input Ports
Ports A and B are 8-bit input ports 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 (to a common ground) from every other sensor, and isolated to the host PC ground.
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 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 opto-isolator, the output goes high, and the port bit is read by the PC at a high logic level (binary 1). While this is true at the hardware level, the Microsoft Windows driver gives the application the ability to use Positive or Negative Logic. This card defaults to Positive Logic and therefore the driver inverts the logic level BEFORE the information is returned to the application. Therefore, a voltage high enough to cause the LED to turn on will be read by the application as a logic high level.
The input impedance of each isolated input is approximately 8200 ohms (factory default). The opto-isolator requires approximately 250uA to turn on. The maximum input current is 25mA. The selection of the input resistor will determine the turn-on voltage for the inputs according to the 8004Hec Socketed Input Resistor Selection Table below. The voltage on the inputs must not exceed 30v for the 8004ec and 36v for the 8004Hec.
The following formulas apply:

• Turn on Voltage = diode drop + (turn on current) x (resistance) [Ex: 1.2+ (.00025) x R]
• Input Current = ((input voltage)-1.2V) / (resistor value)

Increasing the input resistor accordingly can increase the turn-on voltage. Because socketed DIP resistors are utilized, they can easily be replaced with a different value. Sealevel can do this, if necessary.
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.

8004Hec Socketed Input Resistor Selection Table
The following table shows common input resistors and the ranges associated with each.

Input Resistor| Turn-On| Input Range| Max Input| Max Current| Notes
---|---|---|---|---|---
1200W| 1.4V| 1.4 – 18.0V| 18.7V| 15.8mA|
3300W| 1.8V| 1.8 – 29.0V| 30.1V| 9.2mA|
