The QUANCOM® ETHOPTOREL32 board is equipped with 32 opto inputs and 32 opto outputs and is designed for industrial purposes. The relays are SIL-relays which are able to switch encumbrances of 1 A respectivly 15W.

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 fell free to tell us in your order.The default input range is 12V to 30V.

Input edge change

The 32 inputs are equipped with input flip-flops which detect quick input edge changes. 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 operating.

Other features

ZoomThe ETHOPTO32IO example shows the programming with Visual Basic
Each single port of an ETHERNET opto/relay module is equipped with LEDs for optical function controls which enables to show changes of output or input levels.
You can see the module state through a configuration LED, i.e. intitialisation of the operating system, reading or writing accesses or non-evaluated input edge changes are shown. Through simple assembly in a rack you can use the attachment as a standalone equipment in the laboratory area or as a mobile equipment for a notebook anytime. The current supply occurs through an external adapter. The double stick strips for the in- and outputs complete the flexibility of the module.

Several modules of the same type are applicable:

You can use up to 8 modules at the same time with the help of a DIP switch, so you can choose a module adress between 0 ... 15. The software is able to identify each module trough the module adress..

Software support

The ETHOPTOREL32 module is supported by the QLIB (QUANCOM Driver Library) and allows you a simple programming under Windows 7 / Vista / XP / 2000 / Server 2k-2008 R2, Agilent VEE and Labview. There is no annoying installation of the drivers necessary because of the software port QLIB.
YOu don't need any knowlege of driver installation anymore. With QLIB you can easily create applications with Visualstudio.NET, Visual Basic, Visual-C, Borland Delphior other compilers or interpreters. You can also import data to MS Excel, MS access, Labview or Agilent VEE. The Visual Basic example is a small testing programm which allows you to check all relevant functions of the card. Additionally it is a good starting point for own projects.

It is possible to employ the card in all applications which are able to call an external DLL function because QLIB is an API and has its programming port through an DLL.

You can use the same instructions on all supported operating systems. If you created an application on WIndows 95 you can immediatly use it on Windows XP.

The driver of Linux contains also an software port which is very close to QLIB. You can compile your Windows examples without any problems under

ETHOPTOREL32 is also available as ETHOPTO32IO.

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]
