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

It is also possible to get this module in a 3A version. This will result in a different configuration as shown below.Configurations:3A/90W:

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 ExplanationSoftware library
|The 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
