2. Hardware description 2.1. Introduction The USB-OPTOIN-X-RELAIS-X modules provide relays with a maximum switching voltage of 36V DC (max. 1A, 15 watts) and Opto-in inputs, which are suitable for industrial applications for registration of status or even to count the changes of state of the inputs. Our USB modules have been developed for industrial applications for measurement, control and regulation. The modules all feature a USB interface and can therefore be connected to PC systems with USB bus.
2.2. Quick installation 2.2.1. Step 1 - Installation of the software and driver Now install the driver DELIB library with the file "delib_install.exe" from the supplied DEDITEC-Driver CD. These can be found in the "\zip\DELIB\delib_install.exe" on the DEDITEC-Driver CD. Note: On our website www.deditec.de you can always find the latest DELIB driver version. 2.2.2. Step 2 - Connecting of the module Connect your PC via USB cable to the USB connector of the module.
2.3. Technical data USB-Interface (USB 1.1 / USB 2.0) Power supply: +5V (supply occurs over USB bus) 8/16/32/64 opto-coupler inputs (depending on module) Variable input voltage range min 5V, max 30V AC (standard: 15-30V) Galvanically isolated using opto-couplers Logging of impulses between 2 read out cycles 8/16/32/64 Relay outputs (depending on module)(36V, 1A, 15W, Closer-relay) Timeout protection Galvanically isolated using relays Operating temperature: 10°C ..

2.6. J2 - Configuration of the power supply The configuration of the power supply via a jumper.
2.7. Outputs 2.7.1. Relais outputs The relays are able to switch voltages up to 36V. The max. current is 1A at a max. power of 15W. Additionally, the relays provide a safe electrical isolation of the module to the connected equipment. 2.7.2. Timeout-protection The timeout-protection gives the possibility to switch-off automatically the outputs to prevent damage. This takes place, if in a predefined time frame any communication with the module was possible.
2.8. Inputs 2.8.1. Registering short input pulses Schnelle Zustandswechsel an den Eingängen, die innerhalb von größeren Auslesezyklen auftreten, werden durch eine zusätzliche Logik erfasst und können separat per Software ausgelesen werden. 2.8.2. Galvanically decouppled through optocouplers AC input opto-couplers provide a galvanic isolation of the module towards the connected equipment. They also provide a safe connection to the module for reverse currents and high voltage peaks. 2.8.3.

3. Software 3.1. Using our products 3.1.1. Access via graphical applications We provide driverinterfaces e.g. for LabVIEW and ProfiLab. The DELIB driver library is the basis, which can be directly activated by ProfiLAB. For LabVIEW, we provide a simple driver connection with examples! 3.1.2. Access via the DELIB driver library In the appendix, you can find the complete function reference for the integration of our API-functions in your software.
3.1.4. Access via provided test programs We provide simple handling test programs for the most important functions of our products. These will be installed automatically by the installation of the DELIB driver library. So you can test directly e.g. relays or you can check the voltage of an A/D converter.
3.2. DELIB driver library 3.2.1. Overview The following figure explains the structure of the DELIB driver library The DELIB driver library allows an uniform response of DEDITEC hardware with particular consideration of the following viewpoints: Independent of operating system Independent of programming language Independent of the product 3.2.1.1. Program under diverse operating systems The DELIB driver library allows an uniform response of our products on diverse operating systems.
3.2.1.2. Program with diverse programming languages We provide uniform commands to create own applications. This will be solved by the DELIB driver library. You choose the programming language! It can be simply developed applications under C++, C, Visual Basic, Delphi or LabVIEW®. 3.2.1.3. Program independent of the interface Write your application independent of the interface ! Program an application for an USB product of us. - Also, it will work with an ethernet or RS-232 product of us ! 3.2.1.4.
3.2.2. Supported operating systems Our products support the following operating systems: Windows 7 Windows Vista Windows XP Windows 2000 Linux 3.2.3. Supported programming languages Our products are responsive via the following programming languages: C C++ C# Delphi VisualBasic VB.
3.2.4. Installation DELIB driver library Our DELIB Installer start screen. Insert the DEDITEC driver CD into the drive and start „delib_install.exe“. The DELIB driver library is also available on http://www.deditec.
Click on „Install“.
The drivers will be installed.
The DELIB driver library is now installed. Press „Close“ to finish the installation. You can configure your module with the „DELIB Configuration Utility“ (see next chapter). This is only necessary, if more than one module is present.
3.2.5. DELIB Configuration Utility Start the “DELIB Configuration Utility” as follows: Start Programs DEDITEC DELIB DELIB Configuration Utility. The „DELIB Configuration Utility“ is a program to configure and subdivide identical USB-modules in the system. This is only necessary if more than one module is present.
3.3. Test programs 3.3.1. Digital Input-Output Demo Start “Digital Input-Output Demo” as follows: Start Programme DEDITEC DELIB Digital Input-Output Demo. The screenshot shows a test of the RO-USB-O64-R64. The configuration of the module (64 inputs and 64 outputs) is shown on the upper left side.
