The NI PCI-6032E is a multifunction data acquisition module for PCI bus computers, delivering 16-bit analog input measurement with up to 100 kS/s sampling. This E Series card provides 16 single-ended or 8 differential input channels, configurable input ranges from ±10 V down to ±0.1 V (including 15 ranges for signals under 50 mV), and integrated overvoltage protection at ±25 V. The module includes 8 TTL-compatible digital I/O lines, two 24-bit counter/timers with 20 MHz timebase for PWM and encoder inputs, and an RTSI bus for multi-instrument synchronization. Hardware-based analog triggering supports direct analog inputs or postgain signals, while onboard self-calibration eliminates manual calibration procedures.
