The National Instruments 786471-01 Sound and Vibration Input Device, designated as the FD-11634, is an advanced data acquisition solution designed for FieldDAQ applications. This device features eight analog input channels with galvanic isolation between channels and the chassis, allowing for reliable data collection in challenging environments. It has an input voltage range of ±10 V and ±1 V and utilizes a 24-bit delta-sigma ADC with analog prefiltering for high-resolution signal processing. The configurable timebase frequencies include 13.1072 MHz, 12.8 MHz, 12.288 MHz, and 10.24 MHz, enabling flexible sampling configurations.

Data rates are adjustable from a minimum of 500 samples per second to a maximum of 102.4 kilosoamples per second. The 786471-01 supports network synchronization using IEEE 802.1AS over a 1000 Base-TX full-duplex Ethernet connection, with communication protocols including TCP/IP and UDP. It is equipped with two internally switched 8-pin X-coded M12 Ethernet ports that automatically negotiate communication rates of 10, 100, or 1000 Mbps, and can function effectively at a maximum cabling distance of 100 meters per segment.

This device operates on a supply voltage of 9 VDC to 30 VDC with a maximum power consumption of 10 watts. With physical dimensions of 7.8 inches by 3.0 inches by 1.9 inches and a weight of 1.179 kg, the 786471-01 is compact and lightweight. It is designed to perform reliably in extreme conditions, with an operating temperature range of -40 °C to 85 °C and a storage temperature range of -40 °C to 100 °C, while also being able to withstand a relative humidity of up to 100%. This device is certified to meet safety standards including IEC 61010-1, EN 61010-1, UL 61010-1, and CSA C22.2 No. 61010-1, making it suitable for use at altitudes up to 5000 meters.
