A product identical in construction with relays may be found here ( -> RO-USB-O16-R16 - USB-input/output module with 16 inputs and 16 outputs (relays 1A))

USB-interface

Transfer rate

The supported standards are USB 2.0 and USB 1.1. The transfer rates are 12 MBit/s or 1,5 MBit/s.

USB-interface connection (galvanically isolated)

The connection of the module to the PC interface is done through a provided 3m USB adapter cable. The adapter ensures a safe galvanic isolation and allows a cable length of over 100m.

Inputs

Visual monitoring of inputs

The state of every input is directly indicated by a LED. That way, wrong wiring is easily noticeable.

Detecting short input pulses

The module won't miss fast state changes, even if the inputs are sampled in larger periods. Fast state changes between two readout-cycles are detected through an additional logic and can be readout by software. A LED (combined for all inputs) indicates a "state change". The LED does not extinguish until the software register for input state changes is read out.

Counter

Every input channel has a 16 bit counter. Herewith the module "counts" additional events.

Input protection using optocoupler

The inputs have AC-suitable optocouplers. Therefore you don't need to pay attention to the polarity while wiring the inputs.

Input voltage

By default the inputs are designed for a voltage of 24V. They can be adjusted (even later) to 15V, 12V or 5V.

Relay Outputs

Relay-outputs (galvanically isolated, permanent load of 1A AC)

Relays ensure a save galvanic isolation of the outputs. They are designed for up to 36V/1A. Maximum switchable power is 20W.

Timeout-protection

If required, a timeout-protection may be enabled, switching automatically off the outputs to prevent damage. This takes place, when e.g. the communication gets lost. Switching off the outputs is indicated by a LED.

Outputs

Optocoupler-outputs (galvanically isolated)

Every output is realised in MOSFET-technology and is designed for a permanent load of 2A. The short-term load is over 2A (e.g. during switching-on currents). This enables to realize PWM motor-controls. Each MOSFET is controlled by a optocoupler to ensure a safe galvanic isolation.

Timeout-protection

If required, a timeout-protection may be enabled, switching automatically off the outputs to prevent damage. This takes place, when e.g. the communication gets lost. Switching off the outputs is indicated by a LED.

Connector

Easy to maintain connector system

The plug and socket consist of a multipoint socket connector and a multipin connector with a throw-off lever. Plug-in and plug-out is easy as well as rewiring the terminal strip. The wire connection itself is realized with a screwless connector system. A tool is included with each module.

Configuration of USB modules

A configuration of a USB product is not needed - this complete the driver with their Plug and Play mechanism.

Working with several modules

Are more than one USB products working on a system, the driver library differentiate between these modules. Every brand new USB product has the ID "0". The ID can be changed by the DELIB-Configuratin Utility and will be stored in an EEPROM on the module.
So you can use up to eight identical modules on one pc.

Controlling by the DELIB DLL under Windows

The DELIB DLL allows a standard respond of all DEDITEC measurement modules. For this we provide all functions of our products to the software engineer.

With this tool you can test our products very easily. It is easy to handle and supports all modules of DEDITEC. The example above shows a test of a RO-USB-O32 input module.

Examples for responding our products with "C"

In the following example we show you in "C", how to access to our input modules in short time.

1. Step: Open the module

handle = DapiOpenModule(RO-USB,0); // Open USB-module

2. Step: Reading of 16 digital inputs

data = DapiDIGet16(handle, 0); // Read the first 16 digital inputs

3. Step: Close the module

DapiCloseModule(handle); // Close the module

The function "DapiOpenModule" is used to open a special kind of module. Which module should be openend, is defined by the two parameters. The first parameter is for the "module ID". By the integrated "DELIB.H", you can also set this parameter to "RO-USB1". So the driver library recognize, that an ethernet interface will be driven.

The second parameter assigns the module number. If only one module is connected to the pc, the module number is "0". Are there more than one modules in the network, you have to set the correct number.

Controlling of more than one USB-module

Example for opening several modules on one pc:

Open a module with ID "1"

handle1 = DapiOpenModule(RO-USB1,1); // open USB-module with ID=1

Open a module with ID "4"

handle2 = DapiOpenModule(RO-USB1,4); // open USB-module with ID=4

Overview about available DELIB-Functions

Plug connection

Screwless plug connectors

All input and output connectors have a practical, screwless terminal block. An mechanic ejection guarantees a very quick module change without any special tools. Wire connection happens with screwdriver or an included plastic pin. (s. pic.1)

Connection example of a RO-Module

		RO-MODULE
		Step 1: Push the plastic tool into the small notch at the side of the terminal block, to open the clamp contacts for the wire connection.
		Step 2: When you are looking into the wire hole, you can see, that the clamp contacts have been opened. The end of the wire should be bared 5-7mm. Now put it as deep as possible into the opened hole.
		Step 3: After that, pull the plastic tool out of the notch. The clamp is closed again now.
		Step 4: After correct connecting, pull out the wiring by hand isn't no more possible
