About LabJack U12

The U12 series is the original LabJack. The device is solid - the firmware hasn't changed in a decade, and it has a very long service record of reliability and customer satisfaction - all with an attractive price point. It can be used for measurement and control within simple analog and digital systems. We continue to produce and sell U12s because a large number of our customers have integrated them successfully into other products. New applications should consider the U3 series over the U12 because the U3 is faster, more flexible, and is compatible with our wide array of LJTick accessories. Analog Inputs: The LabJack U12 has 8 screw terminals for analog input signals (AI0-AI7). These can be configured individually as 8 single-ended channels, 4 differential channels, or combinations in between. Each input has a ±10 volt input range, 12-bit resolution, and an input bias current of ±90 microamps. Differential channels can make use of the low noise precision PGA to provide gains up to 20. The LabJack U12 is capable of both software and hardware timed acquisition. Analog Outputs: The LabJack U12 has 2 screw terminals for analog output signals (AO0 & AO1). Each analog output can be set to a voltage between 0 and the supply voltage (+5 volts nominal) with 10-bits of resolution. The analog outputs are controlled in command/response mode at up to 50 Hz per channel.
