National Instruments TS-15100 Data Acqusition Module

The National Instruments TS-15100 (Part Number 788269-01) is a versatile data acquisition module designed for precision measurement applications. The TS-15100 is a great option for researchers and engineers working in industries including industrial automation, aerospace, and defense because of its extensive feature set. The module includes 16 differential or 32 single-ended channels, offering flexibility in data acquisition. The device consists of a 16-bit analog-to-digital converter (ADC) ensuring high-resolution measurements. The TS-15100 operates with DC coupling, exceptional for a wide range of measurement tasks, and also includes input voltage ranges such as ±10 V, ±5 V, ±1 V, and ±0.2 V, with a minimum overrange capability of 4% in the ±10 V range. When powered on, the TS-15100's input impedance is greater than 10 GΩ in parallel with 100 pF, ensuring minimal loading on the signal source, while the bias current resides around ±100 pA, which helps maintain accuracy in sensitive measurements.

With a maximum sampling rate of 250 kS/s (4 µs conversion time), the TS-15100 allows for quick data gathering. There is very little interference between channels at 10 kHz thanks to crosstalk of -50 dB for single-ended measurements and -65 dB for differential measurements. The module also has a 350 kHz analog bandwidth. The accuracy varies with range. For instance, with self-calibration, the typical gain error at 23 °C is ±0.017%, and the offset error is ±3.1 mV in the ±10 V range. These values marginally increase in the absence of self-calibration.

Designed to withstand various environmental conditions, the TS-15100 operates effectively in temperatures ranging from 0 °C to 55 °C and can be stored safely in temperatures between -40 °C to 71 °C. It operates within 10% to 90% relative humidity, non-condensing, and can be stored in 5% to 95% relative humidity, non-condensing. The module is also designed to endure operational vibrations from 5 Hz to 500 Hz at 0.3 g RMS and non-operational vibrations up to 2.4 g RMS. It can withstand operational shocks of 30 g, half-sine, for 11 ms pulses.

In terms of power requirements, the module requires a maximum power consumption of 650 mW from the backplane, with thermal dissipation of up to 800 mW. The TS-15100 is lightweight, weighing approximately 39.7 grams (1.40 oz), making it easy to integrate into various systems. The TS-15100's combination of high resolution, extensive input range, and robust environmental tolerance makes it an excellent tool for high-precision data acquisition in demanding applications. Its specifications ensure reliability and accuracy, which are critical for professional and academic research environments.
