The USB interface module EXDUL-381E has eight grounded or four differential 16 bit A / D input channels with bipolar (+/- 0.63 V, +/- 1.27 V, +/- 2.55 V, +/- 5.1 V, +/- 10.2 V) input voltage ranges. The conversion initiation including the associated configuration of the A / D components (area / channel selection) takes place via software command. In addition, the module has 8 digital inputs and 2 digital outputs with electrical isolation via high-quality optocouplers and additional protective diodes. Special high-performance output optocouplers can handle a switching current of up to 150 mA. The module is supplied with the necessary operating voltage via USB or an external voltage source.The connections for the external power supply and the connections for the analog and digital inputs and outputs are fed to a 24-pin screw terminal strip. The programmable LCD display enables the display of digital I / O status information or programmable user-specific data. The compact housing allows use as a mobile module on a notebook or as a control module with mounting on DIN EN mounting rails in control and mechanical engineering.
