National Instruments 786374-01 Voltage Input Device for FieldDAQ.

Part Number 786374-01 is the identifying part number for the National Instruments FD-11601 Voltage Input Device for FieldDAQ. The 786374-01 has 8 analog input channels with galvanic isolation between the channels and the chassis. Likewise, the device has a Delta-sigma ADC with a resolution of 24 bits and analog prefiltering. Similarly, the voltage range in the input channels is ±10.5 V. The timebase frequency can be set to 13.1072 MHz, 12.8 MHz, 12.288 MHz, and 10.24 MHz with an accuracy of ±30 ppm maximum. The sample rate may range from a 
minimum of 500 samples/s to a maximum of 102.4 kSamples/s. 

The 786374-01 supports both the TCP/IP and UDP protocols and uses various network ports: HTTP:80 (configuration only), TCP:3580; UDP:5353 (configuration only), TCP:5353 (configuration only); TCP:31415; UDP:7865 (configuration only), UDP:8473 (configuration only). The default MTU size is 1500 bytes. On the other hand, it has two internally-switched 8-pin X-coded M12 ports for Ethernet/ The communication rates are negotiated between 10/100/1000 Mbps depending on the interface. The maximum cabling distance is 100 m per segment and the maximum hops per line is 15. 

The 786374-01 supports an input voltage range of 9 VDC to 30 VDC while the maximum device power consumption can reach 16 W. A 5-pin L-coded male M12 is used for both power input and power output. Note that the torque for M12 connectors should be 0.6 Nm. The maximum current in the Power IN/OUT terminals is 10 A and a 16 A, slow blow fuse is recommended for external overcurrent protection. 

The 786374-01 measures (7.8 in. × 3.0 in. × 1.9 in.) in physical dimensions and weighs 1.2 kg. Likewise, it has a calibration interval of 1 year. The device 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 to 100 °C.  Note that the device should be operated within a maximum altitude of 5000 m.
