The QUANCOM® SEROPTOREL8 board has 8 opto inputs and 8 relays and is designed for industrial purposes. The relays are able to switch up to 3A / 90W. To switch higher capacity and voltage exernal relays are necessary. This is for example our QUANCOM® MODSSR230 for 230V.

Optocouplers 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 SEROPTOREL8 Ethernet Module. 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

VB SEROPTOREL8 example
The SEROPTOREL8 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 SEROPTOREL8, 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.

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.
