National Instruments NI-9235

The National Instruments NI-9235 (Part Number: 785995-01) is a highly versatile C Series Strain/Bridge Input Module designed for precise strain measurement applications. This module features eight channels, each capable of measuring dynamic strain with an input range of ±29.4 mV/V and accommodating 120 Ω bridge configurations. With a maximum sampling rate of 10 kS/s per channel, the NI-9235 supports high-speed, synchronized measurements, making it ideal for scenarios that necessitate real-time comparison across multiple channels.

For enhanced safety and reduced common-mode noise, the NI-9235 offers reliable isolation with up to 60 VDC continuous isolation and 1,000 Vrms transient isolation. The module is equipped with integrated overvoltage protection, safeguarding against excessive voltage between terminals, set at ±30 V. Each channel includes an independent 24-bit analog-to-digital converter and input amplifier, ensuring optimal performance, while the common excitation supply for EXC terminals adds to its efficiency. The module's shunt calibration circuitry features software-enabled switching and precision resistors, with unique shunt calibration resistors for each channel allowing for independent operation. Constructed with a spring terminal front connector and weighing 5.6 oz, the NI-9235 is designed for seamless integration into high-channel-count measurement systems for CompactRIO or CompactDAQ platforms.
