IO101: 16-bit Analog Input/Output Module

16-bit analog module with 32/16 sequential analog inputs, 8 analog outputs, and 16 digital TTL channels, and Simulink driver blocks

This I/O module offers a powerful combination of high analog input and output channel count, small conversion and settling times, and versatile digital I/O for an excellent functionality/price ratio.

Analog Inputs

  • 32 single-ended or 16 differential channels, multiplexer, all channels share one A/D converter
  • 16 bit resolution
  • Selectable ±10V, ±5V, ±3.3V, 0-10V, 0-5V input range (hardware-selectable, same for all channels)
  • Simulink Real-Time™ analog input driver block with optional low-latency acquisition mode

Analog Outputs

  • 8 single-ended channels, dedicated D/A converter per channel
  • 16-bit resolution
  • 12.375µs update and settling time per channel
  • ±10V output range
  • Simulink Real-Time™ analog output driver block with simultaneous update of all active channels

Digital I/O

  • 16 TLL channels, direction configurable in 2 banks of 8 channels.
  • Software selectable debouncing: 0, 4µs, 64µs, 1ms, and 8ms for each input individually
  • Simulink Real-Time™ driver blocks
