Availability: In Stock SKU: USB-MINI-REL2 USB-MINI-REL4 Category:

The USB-MINI-REL2/4 stick is the smallest output module in our product range. It is available with either 2 or 4 NO outputs. The relays are suitable for low switching capacities up to max. 1A

  • 2/4 relay outputs NO (36V DC / 1A / 24 W)
  • Galvanic isolation between contact and coil: 1.0 kV RMS /1 min
  • Timeout Output protection

Relay outputs

This product uses signal relays with normally open (NO) function. They are suitable for smaller switching capacities and achieve well over 5 million switching cycles. The electrical isolation between input and output circuit is up to 1.0kV.

 

Timeout protection

This module has a time definable timeout protection function. If communication with the module is interrupted in the event of an error, the outputs are automatically switched off and connected systems are thus protected.

Software and control

Our DELIB driver library, which is included with the product, makes it easy to address the product via our API.

 

We offer support for the following programming languages:

  • C
  • C++
  • C#
  • VB
  • VBA
  • VB.Net
  • Java
  • Delphi
  • LabVIEW

We offer support for the following operating systems:

Overview screen of the ICT tool with all functions. These are described in more detail in the following chapters
 

General information on the ICT tool

We have developed the new ICT tool to make commissioning our products as easy and straightforward as possible.
This tool combines all the important functions of our old programs, such as the Configuration Utility, Module Demo and DT-Flasher, in one.
With the ICT tool, you can now easily configure, test, diagnose, flash and debug our products.
In the following chapters, we would like to introduce you to our new all-in-one software in more detail.

Module selection

Here you can integrate your modules into the ICT tool by clicking on the “+” symbol, so that you can then configure or test them.

 ICT-Tool module selection. Display of the ICT-Tool at program start

Start screen

Here you can find some important information about your selected module.
In addition, you can display the manual of the module as PDF or HTML version here.
Under “Show module IDs” you can call up all available module IDs. This ID is needed to integrate our products into your software projects.

 ICT-Tool module info. Display of the ICT tool when the module is open

ICT Treeview

In the treeview on the left side of the program window, you can see the respective forms that are supported by your module.
With a click you can then display this form in the right part of the program and perform possible configurations or tests.

 ICT-Tool Treeview. Presentation of the ICT tool, explanation of the structure

Configuration

USB module configuration

Products with USB interface are automatically recognized by the DELIB driver library. Configuration is only required if several identical USB products are to be used on the same system.

 

Multiple identical USB modules on one system

Each of our USB products is delivered with the module number “0”. When using more than one USB module on a PC / system, a new module no. must first be assigned to each additional module. This assignment is done with the help of our ICT-Tool. Only in this way can a unique assignment take place on the software side. The module number is permanently stored in the product. Up to 255 identical modules can be used on one system.

USB watchdog stick with 2 relays for shift operations

[ref type="prod-group-kurzbeschr-converter"]

This USB-WATCHDOG-STICK monitors your operating PC or server and can reset the hardware independently in case of a program crash. Simply integrate the function of the Watchdog Stick into your application. As soon as a timeout occurs and the watchdog stick is no longer periodically reset, the two relay outputs are switched through. With an appropriate connection cabling, for example, the PC reset could be activated, an external SMS modem can send warnings or a connected siren signals an alarm. With the help of our free configuration tool, you can define how the relays should switch in case of an error.

  • USB 2.0 / USB 1.1 interface
  • Watchdog function
  • Monitoring your control PC or server
  • Timeout times adjustable from 10ms to 10h
  • Windows Watchdog API
  • 2 NO contact relay (NO)
