Analog Inputs:

The LabJack U6 has 14 external analog inputs (AIN0-AIN13). AIN0-AIN3 are available on screw terminals and also on the DB37 connector. All 14 analog inputs are available on the DB37 connector.

The maximum input range is ±10 volts, with software selectable gains of x1, x10, and x100. Each analog input can be measured single-ended, or differentially in even/odd pairs. Analog input resolution is 16 bits at max speed (~20 μs conversion time), increasing to 18+ bits at slower speeds (see Sections 3.1 and 3.2 of the User's Guide). Input impedance is at least 1 GΩ, with typical input bias currents of only 20 nA.

Command/response (software timed) analog input reads typically take 1-4 ms depending on number of channels and communication configuration. Hardware timed input streaming (supported with hi-speed converter only) has a maximum rate that varies with resolution from 4 ksamples/s at 18 bits to 50 ksamples/s at 16 bits.

The U6-Pro has all the features of the normal U6 with the addition of an auxiliary low-speed high-resolution (24-bit) sigma-delta ADC. Analog input resolution varies from 19.5 bits (RMS or Effective) at max speed (4 ms conversion time), to 22 bits at slower speeds (160 ms conversion time).

For more information about the analog inputs see Section 2.7 and Appendix A of the User's Guide. For data rate information see Sections 3.1 and Sections 3.2. The User's Guide can be found on the U6 Support page.

Temperature Sensor:

The LabJack U6 has a temperature sensor located very close to the AIN0-AIN3 screw-terminals. Accuracy is ±2 degrees C (max). This sensor is particularly useful for thermocouple cold junction compensation (CJC).

Fixed Current Outputs:

The LabJack U6 has 2 fixed current outputs of 10 μA and 200 μA. These are useful for measuring resistance (resistors, thermistors, RTDs).

Analog Outputs:

The LabJack U6 has 2 analog outputs (DAC0 and DAC1) that are available both on screw terminals and the DB37 connector. Each analog output can be set to a voltage between about 0 and 5 volts with 12-bits of resolution. The analog outputs are based on a true voltage reference.

The analog outputs are updated in command/response mode, with a typical update time of 1-4 ms depending on communication configuration.

For more information about the analog outputs see Section 2.8 and Appendix A of the User's Guide. For data rate information see Section 3.1. The User's Guide can be found on the U6 Support page.

Digital I/O:

The LabJack U6 has 20 digital I/O channels which can be individually configured as input, output-high, or output-low.

The first 4 FIO are available on screw terminals and the DB37 connector. All 8 FIO and 3 MIO are available on the DB37 connector, and 8 EIO and 4 CIO are available on the DB15 connector. Note that on the U6, CIO0-CIO2 are the same as MIO0-MIO2.

Command/response (software timed) reads/writes typically take 1-4 ms depending on communication configuration. The digital inputs can also be read in a hardware timed input stream where up to 16 inputs count as a single stream channel.

For more information about the digital I/O see Section 2.9 and Appendix A of the User's Guide. For data rate information see Sections 3.1 and 3.2. The User's Guide can be found on the U6 Support page.

Timers:

Up to 4 digital I/O can be configured as timers. The timers are very flexible, providing options such as PWM output, pulse timing, pulse counting, and quadrature input.

For more information about the timers see Section 2.10 and Appendix A of the User's Guide. The User's Guide can be found on the U6 Support page.

Counters:

Up to 2 digital I/O can be configured as 32-bit counters. Since counting is one possible mode of the timers above, the U6 has up to 6 counting inputs.

For more information about the counters see Section 2.10 and Appendix A of the User's Guide. The User's Guide can be found on the U6 Support page.

I/O Protection:

All I/O lines on the U6 are protected against minor overvoltages. The AIN lines can withstand continuous overvoltage of ±20 volts, the FIO lines can withstand up to ±10 volts, while the EIO/CIO/MIO lines can withstand up to ±6 volts.

High Channel Count Applications:

By using USB hubs, many LabJacks can be interfaced to a single PC, providing an inexpensive solution for high channel count applications.

Optional Accessories:

The CB15 is a simple screw terminal breakout for the DB15 connector.

The CB37 (Rev. 2.1) is a simple screw terminal breakout for the DB37 connector. The CB37 (Rev. 1.2) is also available.

The EB37 experiment board also provides screw terminals for the DB37 connector, and in addition provides a solderless breadboard and useful power supplies.

The RB12 provides a convenient interface for the U6 to industry standard digital I/O modules, allowing electricians, engineers, and other qualified individuals, to interface a LabJack with high voltages/currents. The RB12 relay board connects to the DB15 connector on the LabJack, using the 12 EIO/CIO lines to control up to 12 I/O modules. Output or input types of digital I/O modules can be used. The RB12 is designed to accept G4 series digital I/O modules from Opto22, and compatible modules from other manufacturers such as the G5 series from Grayhill. Output modules are available with voltage ratings up to 200 VDC or 280 VAC, and current ratings up to 3.5 amps.

The LJTick-Divider (LJTD) signal-conditioning module is designed to divide 2 single-ended higher voltage analog signals down to 0-2.5 volt signals.

The LJTick-DAC (LJTDAC) provides a pair of 14-bit analog outputs with a range of ±10 volts. Plugs into any digital I/O block, and thus up to 10 of these can be used per device to add 20 analog outputs.

The LJTick-InAmp (LJTIA) signal-conditioning module provides two instrumentation amplifiers ideal for low-level signals such as bridge circuits (e.g. strain gauges) and thermocouples. Each amplifier converts a differential input to single-ended.

The LJTick-RelayDriver (LJTRD) allows 2 digital I/O lines to each control a relay or other moderate load up to 50V/200mA.

The LJTick-CurrentShunt (LJTCS) signal-conditioning module is designed to convert a 4-20 mA current loop input signal into a 0.47-2.36 volt signal.

The LJTick-Proto (LJTP) consists of an 8x8 grid of holes for prototyping custom signal-conditioning modules.
