IO102: Fast 16-bit Analog Input/Output Module With Digital I/O

Fast 16-bit analog module with 32/16 multiplexed analog input channels and 4 analog output channels, and 16 digital TTL channels, and Simulink driver blocks

This I/O module offers lower input sampling and conversion times than the IO101, and therefore smaller overall driver latency times. It is similarly priced to the IO101 but comes with 4 analog outputs instead of 8.

Analog Inputs

  • 32 single-ended or 16 differential channels, multiplexer, all channels share one A/D converter
  • 16 bit resolution
  • Selectable ±10V, ±5V or ±2.5V input range (hardware-selectable, same for all channels)

Analog Outputs

  • 4 single-ended channels, dedicated D/A converter per channel
  • 16-bit resolution
  • 8 µs update and settling time per channel
  • Selectable ±10V, ±5V or ±2.5V output range

Digital I/O

  • 16 TLL channels
  • Direction configurable in 2 banks of 8 channels
