U3-HV. USB DAQ device with 4 dedicated high-voltage analog inputs, 12 flexible I/O, and 4 dedicated digital I/O. The flexible I/O can be configured as either digital or analog, thus providing up to 16 analog inputs, or up to 16 digital I/O. It also has two 10-bit analog outputs, up to 2 counters, and up to 2 timers.
What is LabJack used for?
LabJack Corporation makes data acquisition and control hardware to connect the physical world to your computer. We help you monitor and control your project or application from your PC. In that way, a LabJack device serves as a bridge between the real world and the virtual one.
What is the maximum output voltage of a U3 LabJack?
4.95 volts
The LabJack U3 has 2 analog outputs (DAC0 and DAC1) that are available on the screw terminals. Each analog output can be set to a voltage between about 0.04 and 4.95 volts with 10 bits of resolution (8 bits on older hardware revision 1.20/1.21).
How do you set up a LabJack?
U3 Quickstart Tutorial
- Install the appropriate LabJack driver and software bundle.
- Connect the U3 to the computer or hub.
- Run LJControlPanel.
- Click “Find Devices”.
- Select the connection (i.e. “USB – 1”).
- Click “Test”.
- Connect jumper wire from DAC0 to AIN0/FIO0.
- Control Panel will read the voltage level of AIN0.
What is a Labjack device?
LabJacks are USB/Ethernet/WiFi based measurement and automation devices which provide analog inputs/outputs, digital inputs/outputs, and more. A LabJack is an essential part of a computer-based instrumentation.
How does a Labjack work?
The LabJack U3-LV could be connected to a solid-state relay and used as a simple on-off controller. The device could read an analog input, such as voltage from a thermocouple, then output a digital control signal to a solid-state relay to switch on a fan or heater.
How do you use Labjack U6?
U6 Quickstart for Windows Overview
- Install the appropriate LabJack driver and software bundle.
- Connect the U6 to the computer or hub.
- Run LJControlPanel.
- Click “Find Devices”.
- Select the connection under the device serial number (i.e. “USB – 1”).
- Click “Test”.
- Connect jumper wire securely from DAC0 to AIN0.
What is DAQ device?
DAQ is the process of measuring an electrical or physical phenomenon, such as voltage, current, temperature, pressure, or sound. A DAQ system consists of sensors, DAQ measurement hardware, and a computer with programmable software. Learn more.
What is a USB DAQ?
Included software acquires, displays, reviews, and exports data with ease and without programming. Our hardware and software combinations take you from concept to results in minutes.
What is a LabJack device?
How does a DAQ work?
DAQ hardware is either connected to the computer using the USB ports or through the PCI-Express slots on the motherboard. The DAQ hardware takes in the analog signals from the sensors and converts them to digital signals readable by the computers.
How do I use labjack with the U3?
1. Install the appropriate LabJack driver and software bundle. The utility application referenced in the following steps (LJControlPanel) is only available in the Windows Installer. The package for Linux and Mac will allow communication to the U3, but no similar application is available for Mac and Linux at this time.
What U3 variants are covered in this datasheet?
This datasheet covers all U3 variants: U3-LV, U3-HV, U3-LV-OEM, and U3-HV-OEM. These HTML pages form the complete datasheet, manual, and user’s guide for the U3. Most information in this datasheet applies to all U3 variants.
What is the voltage range of the u3-hv?
The U3-HV has 4 high-voltage channels that have a range of +/-10 volts or +20/-10 volts. For low-voltage channels on a U3, a good solution is the LJTick-Divider. See Section 2.6.3.6 of the U3 User’s Guide. : Could not load labjackud driver. Ethernet connectivity availability only.
Should I get the ljtd-uni21v or the stock uni10v for the u3-lv?
If you go with the LJTD, you could get the stock UNI10V version (attenuates 14V down to 3.5V) and use the 0-3.6V special range on the U3-LV. Or you get the custom LJTD-UNI21V which attenuates 20.5V down to 2.5V.
