National Instruments 784278-01 Analog Input Module
The National Instruments 784278-01 is a high-performance 6-channel analog input module. It is also identified as the PXIe-4481 and is developed for advanced voltage measurement applications. This module is ideal for tasks that require high-bandwidth voltage measurements and supports simultaneous sampling across all six channels. Each channel is independently software-selectable for differential or pseudodifferential voltage measurements along with coupling options for both AC and DC inputs. The NI 784278-01 module features a 24-bit Delta-Sigma analog-to-digital converter (ADC) that provides high-resolution measurements. The ADC supports sampling rates ranging from 100 samples per second up to 1.25 MS/s along with an ADC modulator sample rate of 20 MS/s. The module also offers a FIFO buffer size that accommodates 1,023 samples per task, along with an additional 8,221 samples per channel. It facilitates efficient data transfers through Direct Memory Access (DMA) or Programmed I/O.
The 784278-01 includes analog and digital filtering capabilities that ensure accurate frequency domain measurements for dynamic signal analysis. The module's gain settings are independently software-selectable that provides a full-scale input range from ±0.5V to ±10V. This feature allows users to optimize the module for varying signal amplitudes and maintain measurement accuracy across different signal levels. This input module also offers overvoltage protection up to ±30V on positive inputs and ±10V on negative inputs that protectes the system against potential damage from unexpected voltage spikes.
The 784278-01 input unit is also equipped with robust timing and synchronization features. The features include multiple timing engines and support for internal and external timebases. The module’s effective number of bits (ENOB) ranges from 13.1 to 13.5 that depends on the voltage range. The unit is compatible with Transducer Electronic Data Sheet (TEDS) according to the IEEE 1451 standard that enables seamless integration with smart sensors. This input module operates within a temperature range of 0°C to 55°C and is tested to withstand shock and vibration according to IEC and MIL-PRF standards. This ensures reliable performance even in harsh conditions. With a calibration interval of two years and compliance with international safety and electromagnetic compatibility standards, the 784278-01 is a reliable solution for a wide range of voltage measurement applications.
