National Instruments 783732-01 C Series Voltage Input Module
The National Instruments 783732-01 is a spring-terminal variant of the NI-9221 voltage input module. It identifies as an 8-channel single-ended analog input module built for the C Series platform. The module uses a 12-bit successive approximation register ADC for signal conversion. The input impedance measures 1 MΩ resistance with 5 pF capacitance across each channel. The overvoltage protection extends to ±100 V channel-to-COM for added circuit safety. Its settling time to 1 LSB measures 1.25 μs across the input range.
The 783732-01 voltage input module calibrated accuracy reaches ±0.04% gain error at 25 °C. Each of the 8 channels on this device accepts an input range of ±60 V. The maximum aggregate sample rate reaches 800 kS/s on standard chassis and 475 kS/s on R Series expansion chassis. This wide voltage range suits industrial-level and automotive measurement applications. The input bandwidth on the unit reaches a minimum of 950 kHz at -3 dB. Its offset error under calibrated typical conditions measures ±0.07% of the 62.50 V range. The gain drift stays within ±34 ppm/°C across the full operating temperature band. The offset drift remains within ±580 μV/°C for stable long-term measurements.
This NI spring-terminal module weighs 152 grams for compact chassis integration. Its wire gauge compatibility spans 0.2 mm² to 2.5 mm². Its insulation strip length for spring-terminal wiring measures 13 mm from the wire end. The channel-to-COM safety voltage on this model reaches ±60 V DC maximum. Its withstand voltage rating reaches 2,300 V RMS through a 5-second dielectric test. The shock tolerance on the 783732-01 reaches 30 g at an 11 ms half sine profile. The module carries an IP40 ingress protection rating for enclosed environments. A maximum altitude rating for operation reaches 2,000 meters above sea level.
The power consumption in active mode stays within 1 W maximum for the voltage input module. Its vibration tolerance includes 5 g RMS random vibration from 10 Hz to 500 Hz. Its sleep mode power consumption drops to 1 mW maximum for reduced idle draw. The calibration interval for this module is set at 1 year. Operating temperature range for this module spans -40 °C to 70 °C.
