The QUANCOM® ETHOPTO32IO board is equipped with 32 opto inputs and 32 opto outputs and is designed for industrial purposes.

Optocouplers protect the inputs up to 500 Volts

. Your personal computer is protected against damage in case of overvoltage by galvanic isolation. These optocouplers are designed as alternating current optocouplers which means that you can choose the polarity of input signals optionally . You can also accommodate the input voltage range individually. If you want to have an input range from 5V to 12V feel free to tell us in your order. The default input range is 12V to 30V.

Change of input states

The 32 inputs are equipped with input flip-flops which detect quick input state changes or remove switch bounce. It is also possible to generate an interruption if an input changes.

Output protection

The board has a configurable onboard timeout control which switches the outputs in case of a software hanging off. You can also select a time period. (i.e. 16s) Through this function you can switch off connected terminals like motors or hot plates to avoid uncontrolled working processes.

Software library

ZoomThe ETHOPTO32IO example shows the programming with Visual Basic
You need no knowledge in driver development. We implemented a command set which is usable for all operating systems. An application that controls the ETHOPTO32IO, and which is generated for Windows 98 can be used directly on a Windows XP PC.

With 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 VB ETHOPTOREL32 examples which show how to program and test the card and it also includes the source code. This is a good starting point for your own applications.

ETHOPTO32IO is also available as ETHOPTOREL32 .

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.

Command Line Tool to Change Module Address
This command line tool makes it possible to change the address of your module by software.

Note that therefore the installed Firmware has to be higher or equal to Version 1.30 and the switch in the QLIB Configuration Utility must be set correctly.

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]
