The PCIOPTOREL16 opto board has 16 inputs and 16 relays and is designed for industrial purposes.

Optocouplers are protecting the inputs up to 500 Volts
All inputs are protected by optocouplers. This ensures protection for your personal computer in heavy electrically polluted environment. These optocouplers are designed as AC-optocouplers which means that the polarity of the input signal makes no difference. Also all the inputs have no common ground, so that each of the inputs signals may have a different ground-signal. If you want to have an input range from 5V to 12V you may tell us with your order. The default input range is 12V to 30V.

Input edge detection
The 16 inputs are equiped with input flipflops which detect quick input state changes or remove switch bounce. This allows the detection of fast input changes. It is also possible to generate an interrupt if an input changes.

Timeout control
The board has a configurable onboard timeout control which detects all writes to the PCIOPTOREL16 hardware. If the software hangs and the board isn't controlled by the personal computer the outputs are switched off. Think about a heating which overheats or even burns because the PC is "to busy" to switch the heating off. You may setup the timeout-time from 1ms to 16 hours in different steps. This feature can be switched off by a software command.

Software library

ZoomThe PCIOPTOREL16 example shows the programming with Visual Basic
You need no knowledge in the driver development. We implemented an command set which is the same for all operating systems. An application that controls the PCIOPTOREL16, and which is generated for Windows 98 can be used directly on a Windows XP PC.

With the QLIB it is easy to create applications with Visual-Studio .NET, Visual-Basic, Borland Delphi or other modern compilers. Even an interface to MS Excel, MS Access or Sun Java is available. We included the VB PCIOPTOREL16 Sample which shows how to program and test the card and it also includes the source code. This is a good starting point for your own applications.

The QLIB is a API which provides it's functions through a Windows DLL, so it is possible to use QLIB with all applications that allow access to external DLL Functions.

The PCIOPTOREL16 is also available as USB module USBOPTOREL16 .

QCLI (QUANCOM Command Line Interface)
The QUANCOM Command Line Interface (QCLI) was made for all those which don´t have programming experience or knowledge.

It is a simple command line tool which makes it able to control our I/O and Watchdog boards with some very simple strings.

Note that this procedure is not as fast as a programm written in a higher programmiung language, for example C.

QCLI (QUANCOM Command Line Interface)
Das Quancom Command Line Interface (QCLI) ist für diejenigen gedacht, die sich in der Programmierwelt nicht zurechtfinden, oder auch keine Lust haben sich ein eigenes Programm für den Zugriff auf unsere QUANCOM Karten zu schreiben. Da das QCLI recht simpel gehalten ist, ist es um ein wesentliches langsamer, verglichen zu einem gut programmierten Programm. Mit einfachen Funktionen der QAPI lassen sich über das QCLI QUANCOM Karten und Module bedienen und konfigurieren. [Download 32.1KB]
