NI DAQCARD-4350

NI lists DAQCard-4350 by exact model name on its archived legacy portable device support matrix, confirming it as a primary NI hardware model rather than an accessory. In separate official documentation, NI defines the NI 435x family as covering NI 4350 and NI 4351 devices and describes that family as high-precision temperature and voltage meters. https://www.ni.com/en/support/documentation/supplemental/08/archived--traditional-ni-daq-and-daqmx-driver-support--legacy-po.html ; https://docs-be.ni.com/bundle/370841b/raw/resource/enus/370841b.pdf

At the NI 435x family level, NI states support for accurate thermocouple and DC voltage measurements, and also for temperature measurement with RTDs or thermistors, resistance using built-in precision current sources, and current measurement using external shunt resistors. NI further states that the hardware uses a 24-bit sigma-delta ADC with differential analog inputs. https://docs-be.ni.com/bundle/370841b/raw/resource/enus/370841b.pdf

The NI 435x manual shows channels CH0 through CH15, supporting family-level description of 16 differential analog input channels. NI also specifies six bipolar DC voltage ranges of ±625 mV, ±1.25 V, ±2.5 V, ±3.75 V, ±7.5 V, and ±15 V, with input protection to ±42 VDC when powered on and ±17 VDC when powered off. https://docs-be.ni.com/bundle/370841b/raw/resource/enus/370841b.pdf
