2. Isolation: Each channel is electrically isolated to prevent interference and protect the PC from high-voltage transients.
3. A/D Conversion: The onboard 12-bit ADC converts the analog input into digital form at up to 800 samples per second.
4. Data Transfer: Converted data is transferred to the PC memory via the AT bus interface, where it can be processed, displayed, or logged by user software.
5. Digital I/O Control: The TTL I/O lines can be used for triggering, control signals, or synchronization with external devices.
