Schematic of LucidControl USB Analog Input Module

Fig. 2-1 Schematic of LucidControl USB Analog Input Module

Fig. 2-1 shows the sketch of the USB Analog Input Module with 4 analog voltage inputs (AI0 ~ AI3).

All LucidControl USB IO modules have two connectors, the USB-Connector and the IO-Connector. Because of this the modules are very easy to connect and to set-up.

While the upper USB connector is used for interconnection with the computer, the lower IO-Connector is used for inputs and outputs.

The IO-Connector provides 8 terminals in total – two for each input.


2.1 Analog Input Configurations

LucidControl USB Analog Input modules are available in different options covering positive and negative input signals.

Module Type Type Number Input Voltage Range
VMin VMax
Positive Inputs LCTR-AI4-5 0 V 5 V
LCTR-AI4-10 0 V 10 V
LCTR-AI4-24 0 V 24 V
Symmetrical Inputs LCTR-AI4-5S -5 V 5 V
LCTR-AI4-10S -10 V 10 V
LCTR-AI4-24S -24 V 24 V

The module can measure voltages within the range VMin to VMax.


2.2 Interface and Interconnection


2.2.1 USB Connection

Please see LucidControl User Manual for more information.

LucidControl AI4 is rated with a maximum current of 40 mA.


2.2.2 IO Connection

LucidControl Analog Input Schematic Connection

2.2.2-1 Analog Input Connection

Fig. 2.2.2-1 shows the interconnection of the module in a typical application.

The analog input voltages are represented by voltage sources of voltages within the valid range.

The terminals 2, 4, 6 and 8 are internally connected to ground.

Attention

All inputs are protected against overvoltage. Applying a voltage higher than VInMax = 30 V may damage the input.
All inputs are protected against faulty polarity. Applying a voltage lower than –VInMax = -30V may damage the input.


2.3 Setup of Hard- and Software


2.3.1 Microsoft Windows®

Please see LucidControl User Manual for more information.


2.3.2 Linux

Please see LucidControl User Manual for more information.


2.3.3 Installation of LucidIoCtrl Command Line Tool

Please see LucidControl User Manual for more information.


2.3.4 Ready to Start

After the module has been installed successfully (if it was necessary at all) the green power LED is switched on and signals that the module is ready for use.

The following examples demonstrate the functionality of the module by using the LucidIoCtrl command line tool.

Windows Examples
For all examples it is assumed that the module is connected to COM1.

Reading the voltages of all 4 input channels
LucidIoCtrl –dCOM1 –tV –c0,1,2,3 –r [ENTER]
-> CH00:5.000 CH01:5.000 CH02:5.000 CH03:5.000

Linux Examples
For all examples it is assumed that the module is connected to /dev/ttyACM0.

Reading the voltages of all 4 input channels
LucidIoCtrl –d/dev/ttyACM0 –tV –c0,1,2,3 –r [ENTER]
-> CH00:5.000 CH01:5.000 CH02:5.000 CH03:5.000
