National Instruments 786471-01 Sound and Vibration Input Device for FieldDAQ

Part Number 786471-01 is the identifying part number for the National Instruments FD-11634 Sound and Vibration Input Device for FieldDAQ. The 786471-01 has 8 analog input channels and features galvanic isolation between channels and the chassis. The input voltage range (AI+ to AI-) is ±10 V, ±1 V. Likewise, it features a delta-sigma ADC with a resolution of 24 bits and analog prefiltering.

The timebase frequencies can take values of 13.1072 MHz, 12.8 MHz, 12.288 MHz, or 10.24 MHz and base clocks can also be synchronized with other FieldDAQ devices using the network synchronization feature. The sampled data rate ranges from a minimum of 500 samples/s to a maximum of 102.4 ksamples/s. The 786471-01 uses EEE 802.1AS for network synchronization over 1000 Base-TX, full-duplex interface. Both the TCP/IP and UDP protocols are used. Likewise, there are two 8-pin X-coded M12 Ethernet ports that are internally switched. Communication rates are auto-negotiated between 10, 100, or 1000 Mbps and the maximum cabling distance is 100 m per segment. 

The 786471-01 has an input voltage range of 9 VDC to 30 VDC and a maximum power consumption of 10 W. It measures (7.8 in. × 3.0 in. × 1.9 in.) in physical dimensions and weighs 1.179 kg. The 786471-01 is recommended for operation between -40 °C to 85 °C at a relative humidity of up to 100%. On the other hand, it can be stored between -40 °C and 100 °C at the same relative humidity levels. Note that it is meant for use within a maximum altitude of 5000 m. The device is designed to meet the requirements of the following safety standards:  IEC 61010-1, EN 61010-1, UL 61010-1, and CSA C22.2 No. 61010-1.
