    Feature 
      
    
      - Simple expansion (via AI-EXP48 option) results in 32DI/64SE analog inputs
 
      - Any analog input can measure voltage or thermocouples—any TC type on any channel
 
      - Over-sampling  mode, including line-cycle rejection for ultra stable TC and low-level  voltage measurements, even in the presence of AC power line noise
 
      - 2 timer outputs
 
      - Synchronous  I/O, where all analog inputs, digital I/O and counter/timer I/O can  occur synchronously, resulting in precise time correlation between all  I/O
 
      - Low latency control outputs capable of responding to inputs in as fast as 2 µs
 
      - 1 MS/s, 16-bit A/D converter 
 
      - 8 differential or 16 single-ended analog inputs
 
      - 24 digital I/O lines
 
      - 4 counter inputs capable of measuring frequency, period, pulse width, or quadrature encoders up to 20 MHz
