The LabJack U12 is the simplest member of the family, with 12 analog inputs (12 bit ±10 VDC, programmable gain amplifier), 20 digital IO, 2 voltage outputs and USB interface.

Screw terminal connections, with short-circuit and overvoltage protection, for the extra 16 digital I/O on the LabJack U12.

High-level linear voltage output and high accuracy. Operating temperature range from 0 to +150 °C.

The most economical member of the LabJack family, the U3-LV has 16 flexible I/O (digital input, digital output, 12 bit 0 to 3.6 VDC analog input), 2 voltage outputs and USB interface.

The most economical member of the LabJack family, the U3-HV has 12 flexible I/O (digital input, digital output, 12 bit 0 to 3.6 VDC analog input), 4 HV analog inputs (12 bit -10 to 20 VDC), 2 voltage outputs and USB interface.

Provides convenient screw terminal access to 12 digital I/O available on a DB15 connector.

A signal conditioning module that divides 2 single-ended uni-polar channels of 0 to 10 V analog signals down to 0 to 2.5 V signals. V_output = V_input/4 

Plugs directly into the standard screw terminal block found on newer U3/U6/UE9/T4/T7. On board switch allows 5 various gain settings, one of them being custom.

Allows 2 digital I/O lines on a U3, U6 and UE9 to each control a relay or other moderate load. Each has a switch to ground (i.e open-collector) that can hold off up to 50 V and can sink up to 200 mA.
