National Instruments 779785-01 Voltage Input Module
National Instruments part number 779785-01 is an identifying part number for the NI-9229 Voltage Input Module, an exceptional choice for general-purpose applications. The NI-9229 module, part of the C series voltage input modules by National Instruments, features 4 analog input channels, a 50 kS/s per channel maximum sampling rate, and a 24-bit analog input resolution across all three part numbers. It boasts independent analog input channels, each with its own signal path and analog-to-digital converter (ADC), enabling simultaneous sampling across all channels.
The NI-9229 module features robust filtering technologies, using analog and digital filters to ensure precise signal representation within specified frequency bandwidths—passband, stopband, and anti-imaging bandwidth. The 779785-01 stands out by employing a screw terminal front connection type and no conformal coating, compared to the other part numbers of the NI-9229. Part number 779785-01 features a 250 Vrms channel-to-channel isolation, enhancing safety and minimizing noise interference, crucial in environments with high electrical disturbances. In comparison, it also offers 250 Vrms channel-to-channel isolation with screw terminals but includes conformal coating for enhanced protection in adverse conditions. The absence of conformal coating in the product means it is suitable for applications where precision and isolation are necessary, but the ability to withstand extreme environments is not paramount.
Additionally, part number 780180-01 with 60 VDC channel-to-channel isolation features a BNC connector, catering to setups requiring quick connections. Part number 779785-01 is lighter than its BNC connector counterpart, weighing 147 grams (5.2 ounces). Its dimensions are 2.783 inches (70.68 mm) in height, 3.469 inches (88.11 mm) in depth, and 0.900 inches (22.86 mm) in width.
Thanks to its compact design, the 779785-01 does not require significant space rearrangements. It is designed to handle specific safety voltage limits to ensure safe operation. For channel-to-channel and channel-to-earth ground connections, it can continuously handle up to 250 Vrms under Measurement Category II. The safety voltage limits for environments classified as explosive atmospheres are lower, with both channel-to-channel and channel-to-earth ground voltages capped at 60 VDC under Measurement Category I.
