LabJack is an EPICS module that supports LabJack T-series I/O modules. 

 

Previous releases of the LabJack module just used the EPICS Modbus driver, and only provided basic support. 

 

This release is a driver derived from asynPortDriver, and it supports the more advanced features of the LabJack devices.

 

The driver supports the 4 current T-series modules:

 

LabJack T4: https://labjack.com/products/labjack-t4

- 4 single-ended analog inputs

  - +- 10V range

  - 12-bit

  - Up to 50 kHz total streaming input rate, i.e. 1 channel at 50 kHz, 2 channels at 25 kHz, etc.

- Up to 8 additional analog inputs (0-2.5 V range, 12-bit).  These can also be configured as digital I/O bits.

- 2 analog outputs

  - 0-5V range

  - 10-bit

  - Up to 50 kHz streaming output rate

- 20 digital I/O bits

  - Rach configurable as input or output.

  - 8 of these can configured as 0-2.5V analog inputs.

- $245

 

LabJack T7: https://labjack.com/products/t7

- 14 single-ended / 7 differential analog inputs

  - Programmable range (+-10V, +-1V, +-0.1V, +-0.01V)

  - 16-bit

  - Up to 100 kHz total streaming input rate, i.e. 1 channel at 100 kHz, 2 channels at 50 kHz, etc.

- 2 analog outputs

  - 0-5V range

  - 12-bit

  - Up to 100 kHz streaming output rate

- 23 digital I/O bits

  - Each configurable as input or output.

- $520

 

LabJack T7-Pro: https://labjack.com/products/labjack-t7-pro

- Same as the T7 except that each analog input can be software switched between 16-bit and 24-bit ADC, trading off resolution for speed.

- In 24-bit mode the ADCs support 9 types of thermocouple inputs.

- $750

 

LabJack T8: https://labjack.com/products/t8

- 8 differential analog inputs

  - 11 input ranges from +-11V to +-0.15 V

  - 24-bit sigma/delta ADC

  - Supports 9 types of thermocouple inputs

  - Up to 40 kHz streaming input per channel, i.e. up to 320 kHz total scanning rate.

- 2 analog outputs

  - 0-10V range

  - 16-bit

  - Up to 40 kHz streaming output rate

- 23 digital I/O bits, each configurable as input or output.

- $1,400
