National Instruments 786575-01 Wireless Vibration Measurement Device

Part Number 786575-01 is the identifying part number for the National Instruments MON-10467 Wireless Vibration Measurement Device. The 786575-01 features 12 input channels and 4 delta-sigma ADCs with analog pre-filtering and a resolution of 24 bits. The sampling rate is dependent on the internal timebase and the decimation rate. For example, at a decimation rate of 32 and passband of 10.24 kHz, the data rate is 25.6 kS/s. The internal master timebase has a frequency of 13.1072 MHz with an accuracy of  ±100 ppm. Likewise, the input coupling on these channels can be selected as AC or DC with software. 

The wireless acquisition system on the 786575-01 has a maximum per-channel record length of 5 s at a 25.6 kS/s data rate and 10 s at a data rate of ≤ 12.8 kS/s. The maximum number of acquisition channels is 12. The wireless radio is based on the Bluetooth Low Energy (BLE) standard and has a frequency range of 2.400 GHz to 2.4835 GHz. The RF transmitter has a maximum RF output power of 18 dBm while the RF receiver has a maximum input power of -5 dBm. 

The 786575-01 supports DC inputs of  ±30 V and AC inputs of  ±30 V peak. The channel-to-channel common-mode voltage range is ±0.6 V. The device works with the InsightCM application software version 3.4 or later. The AC variant of the device requires an AC input with a rating of  100 V AC to 240 V AC, 50/60 Hz, 10 W, and the operating voltage range is 85 V AC to 264 V AC while the nominal input frequency is 50/60 Hz. On the other hand, the device requires DC input of input rating 24 VDC and input power of 6 W (maximum). The operating DC voltage range is 19 VDC to 30 VDC. The device measures (11.61 in. × 12.32 in. × 4.37 in.) and  (11.61 in. × 16.09 in. × 4.37 in.) without and with antenna respectively.
