UDAQ-1408DA, UDAQ-1408DE

UDAQ-1408DA and UDAQ-1408DE are multifunctional modules for the PC USB interface.

The modules are intended for common applications. They are fitted with 14-bit ADC, allowing to measure up to 40,000 measurements per second, featuring programmable amplifier and multiplexer.

The UDAQ-1408DA module features eight differential non-isolated analog inputs (ie. analog inputs GND signal is connected to the PC common ground), two digital inputs operating with HC/TTL signal levels (non isolated) and one relay output. The analog inputs use the D-Sub 25 connector, digital inputs and outputs use the plug-in terminal block.

The UDAQ-1408DE module features are identical to UDAQ-1408DA, but the analog inputs are isolated from the PC common ground.

Both types feature low consumption and they are powered from the USB port only.
