Description
1. Product Title
National Instruments NI‑9205‑ 32‑Channel 16‑Bit C‑Series Voltage Analog Input Module
2. Product Overview
The NI‑9205 is a multiplexed C‑series analog voltage input module designed for NI CompactDAQ and CompactRIO measurement and control platformsNI. It supports flexible channel configuration with up to 32 single‑ended or 16 differential analog input channels for multi‑point voltage acquisition. Equipped with a 16‑bit ADC and programmable gain amplifier, NI‑9205 offers four configurable input ranges to adapt to different sensor output levels. Built‑in over‑voltage protection and isolation circuits defend measurement electronics against field‑side surge damage caused by mis‑wiring or transient noise. This module converts analog field sensor signals into digital data for host system processing, delivering high‑density, cost‑effective multi‑channel sampling for test benches and condition‑monitoring setups while reducing signal acquisition hardware complexity.
