USB digital to analog conversion (USB DAC) of 4 voltages / currents
The USB Analog Output Module generates 4 programmable analog voltage or current sources and it is available for different output voltage ranges: 0-5V, 0-10V.
Optionally, the USB Analog Output Module is also available for negative output voltages of ±5V, ±12V.
Two of the four output terminals can be combined in order to create up to two floating output voltages without having a common ground line with the host computer.
The current output option of the USB Analog Output Module provides current sources of 4-20mA instead of voltages. It is dedicated to build USB programmable 4-20mA interfaces. 4-20mA interfaces are the industry standard for reliable long distance transmissions of measurement signals. The advantage of 4-20mA interfaces is the elimination of the transmission line itself.
Current sources drive a specified current through a load. Because of the limited current provided by USB, the maximum ratings must be considered.
In order to fit the application best and in order to reduce the consumed power the a minimum, current outputs are carried out in two different ways fitting two different burden resistors of 250 and 500 Ohms.
High precision USB DAC Module
All analog output channels are independent and have a accuracy of 0.25% and a resolution of 12 bit.
True 0 Volt output
The outputs are able to drive exactly 0.0V without an offset.
Typical Application: 0-10V and 4-20mA Interfaces
The 0-10V option is best suited to generate 0-10V interfaces as they are wide-spread in automation, home automation and building sector.
For example, the module can control the flow of pumps or the power of central heating units.
Additionally, 0-10V interfaces are often used in order to control the brightness of lightning. The USB Analog Output Module is able to supply up to 4 voltages and hence it can control up to 4 lightning systems.
In combination with the AI4 USB Analog Input Module, which provides 4 analog input channels, a reliable transmission of measurement data can be realized with the 0-10V interface.
For long distance transmission it is recommended to realize a 4-20mA interface by using the 4-20mA current option of the USB Analog Output Module.
Galvanic USB Isolation
All LucidControl USB IO Modules are available with galvanic USB isolation. Contact us for more information.
Bus Powered – No Power Supply needed
All LucidControl are most cost-effective because the required power is supplied by USB and they do not need additional power supplies. Since the Analog Output Modules are able to drive high voltages and high currents the USB current limits must be taken into account and an additional USB hub with external power supply is recommended.
Industrial ready Design
The housing of LucidControl can be directly mounted on standard DIN-Rails ready for switch board assembly.
Using industrial standard IO connectors ensures reliable interconnection.
Easy installation of Hard and Software
LucidControl modules are easy to install and start working immediately after set up.
The IO Modules are compatible with Windows, Linux, Raspberry Pi and Beagle Bone
LucidControl provides drivers for all major operating systems. Command line tools and APIs for Windows and Linux are available.
API is available for .NET, Java and Python.
