The RTD Embedded Technologies DM6430HR-1 is a PC/104 form factor data acquisition module delivering 16-bit analog I/O with full AT bus interface and DMA support. It captures analog signals at 100 kHz with 10 µs conversion time, processes up to 16 single-ended or 8 differential input channels across ±10V range, and generates two 16-bit analog outputs. The module integrates programmable digital I/O, dual 16-bit timer/counters, and an 8 MHz on-board clock for precise timing and synchronization in embedded systems.
