Is a USB/Ethernet based multifunction data acquisition and control device. It features high data acquisition rates together with a high resolution ADC
Analog Inputs:Â
The LabJack T7 has 14 external analogue inputs (AIN0-AIN13). AIN0-AIN3 are available on screw terminals and also on the DB37 connector. All 14 analogue inputs are available on the DB37 connector. The Mux80 multiplexer can expand this to to 80 single ended or 40 differential channels.
The maximum input range is ±10 volts, with software selectable gains of x1, x10, x100 and x1000. Each analogue input can be measured single-ended, or differentially in even/odd pairs
Command/response (software timed) analogue input reads typically take 1-4 ms depending on number of channels and communication configuration. Hardware timed input streaming has a maximum rate that varies with resolution from 4 ksamples/s at 18 bits to 50 ksamples/s at 16 bits
It is possible to connect thermocouples directly to the T7. The T7 has an internal temperature sensor, which can be used for cold junction compensation. DAQFactory contains thermocouple linearisation as a built-in conversion function.
For more information about the analog inputs see Section 15 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 T7 Support Page .
Analog Outputs:Â
The LabJack T7 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 0 and 4.9 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 1.2-4.0 ms depending on communication configuration.
For more information about the analog outputs see Section 16 of the User's Guide on the Support Page
Digital I/O:Â
The LabJack T7 has 23 digital I/O channels which can be individually configured as input, output-high, or output-low. 8 of these lines are called flexible digital I/O (FIO) and can be software configured as up to 6 timers and 2 counters.
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 3 CIO are available on the DB15 connector.
Command/response (software timed) reads/writes typically take 1.2-4.0 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 14 and Appendix A of the User's Guide. The User's Guide can be found on the T7 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.
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 T7 has up to 6 counting inputs
I/O Protection:
All I/O lines on the T7 are protected against minor overvoltages.
Power Supply:Â
Power can be provided by the USB cable or an external 5 volt supply (included). When only Ethernet is connected, and an isolated power supply is used (such as the included wall-wart), the entire T7 is electrically isolated.
High Channel Count Applications:Â
By using USB hubs or Ethernet switches, many LabJacks can be interfaced to a single PC, providing an inexpensive solution for low-speed high channel count applications.
Modbus:Â
Modbus is an industry standard command/response protocol for data acquisition and control equipment. The T7 supports Modbus/TCP in hardware, so any software that supports Modbus/TCP can talk to the T7 with no further software/drivers required. (More Info)
