DMM-32DX-AT

Analog I/O PC/104 Module Advanced Automatic Autocalibration

Description

Overview

Analog I/O PC/104 Module with Advanced Automatic Autocalibration

DMM-32DX-AT is an advanced embedded A/D board.  It includes a comprehensive suite of analog and digital features to fit a wide variety of embedded application needs:

  • The 32 A/D input channels feature high-accuracy 16-bit resolution, 250KHz maximum sampling rate, programmable input ranges, and user-selectable single-ended / differential configuration.
  • The 4 D/A output channels feature user-selectable output ranges as well as a programmable waveform generator feature, 16-bit standard, 12-bit optional.
  • The 24 digital I/O feature bit by bit direction programmability as well as buffers for enhanced output current of -15mA (logic 1) / 64mA (logic 0).
  • The on-board programmable counter/timer circuitry includes a 32-bit counter/timer for A/D and D/A sample timing, as well as a 16-bit counter/timer for general counting, timing, and programmable interrupt functions.
  • Extended temperature operation of -40°C to +85°C is tested and guaranteed. Using our patented auto-autocalibration technology, DMM-32DX-AT will provide accurate analog measurements across its entire rated operating temperature range, ensuring reliable performance for critical applications.
  • Our advanced Universal Driver software is included free with DMM-32DX-AT and all our SBC and I/O boards. The Universal Driver provides a programming library that simplifies control of all the board’s features and enables you to develop your application software quickly.
  • Board uses only ceramic capacitators for durability in high altitudes and other harsh environments.
