Comparison

 

The U3, U6, T4, or T7 are recommended for most new applications:

U3:  12-bit analog inputs.  USB only.  $115.

T4: 12-bit analog inputs.  USB & Ethernet.  $199.

U6:  16-bit analog inputs.  USB only.  $319.

T7:  16-bit analog inputs.  USB & Ethernet (& WiFi on the -Pro version).  $429.

Pro (U6 or T7):  Also adds a 2nd ADC with 24-bit resolution for lower speed (4-160 ms per sample) measurements.

The U3 is our lowest cost device and great for the most cost sensitive applications where 12-bit analog inputs are adequate.  The U6 is in the same family but has a greatly improved analog input system.  Both of these devices are supported on Windows by our UD library and on Linux and Mac by our low-level Exodriver.

The T4 is our lowest cost device with support for Ethernet communications.  It essentially a cross between a U3-HV and a T7.  It is easy to use with the LJM library (Windows/Linux/Mac support) and it is fully compatible with Modbus TCP.

The T7 is our best and most feature packed device.  It has the same analog input system as the U6 (except with 2x the max speed), adds Ethernet in addition to USB, and many other improvements over the U6.  Like the T4, it is easy to use with the LJM library (Windows/Linux/Mac support) and it is fully compatible with Modbus TCP.
