The QUANCOM® USBREL64 Board has 64 relays (1A) and is designed for industrial purposes. The relays are able to switch encumbrances of 1 A respectivly 15W. To switch higher encumbrances a external relay is needed. QUANCOM® is able to offer you many different types of external relays like i.e. our QUANCOM® MODSSR230.
 Connection Samples

It is also possible to get this module in a 3A version. This will result in a different configuration as shown below.

3A/90W: 32 SIL-Reed Relais with 3A/90W + 32 SIL-Reed Relais with 1A/15W
1A/15W: 64 SIL-Reed Relais with 1A/15W

Timeout control
The ETHREL64 supports a timeout control which switches off all outputs if the controlling software does not communicate with the module for a configurable time. For example, if the software hangs and the board can´t communcate with the personal computer the outputs are switched off. Think about a heating which overheats because the PC is "to busy" to switch the heating off. You may setup the timeout period from 1ms to 16 hours in different steps. This feature can be switched on or off by a software command.
 Timeout Control Explanation

Software library
ZoomThe ETHREL64 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 ETHREL64, 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 ETHREL64 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 ETHREL64 is also available as ETHOPTO64OUT and ETHOPTO64IN .

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]
