OPCARD 2.0 is a complete ultrasonic testing device, suitable for all ultrasonic measurements and due to many additional digital inputs/outputs and internal processor it can be used as a controller for more complicated devices.

The card can work together with following devices:

· 32 channel multiplexer - the card can control it directly;
· Scanner - it has input for incremental encoders;

The card has an implemented one channel pulser & receiver and can be used with one transducer or with two (one is sending, and the second one receiving).
