783311-01
789130-01
±500 mV, 50 kS/s/ch, 24-Bit, Simultaneous Input, 4-Channel C Series Voltage Input Module
Overview
The NI-9238 performs differential analog input. The measurement range is compatible with many low-voltage sensors such as current shunts and current transducers in high-current applications. When used with higher-voltage C Series Voltage Input Modules, the NI-9238 can measure power and energy consumption for applications such as appliance test, industrial machine monitoring, power quality analysis, phasor measurements, and harmonic analysis.

NI-9238 Accessories and Software
- Product (Part Number)DescriptionRecommended use casesFlexLogger Professional (785748-3501)FlexLogger Professional, Subscription License, Download
Recommended for automated, extensible data logging with NI data acquisition (DAQ) hardware. Automate tests using alarms, triggers, and events, and expand capabilities with plug-ins.
Key Features
- Multichassis synchronization—Synchronize multiple NI chassis for accurate, time-aligned measurements across high channel counts.
- Logging triggers—Start, stop, or segment data recording automatically based on sensor thresholds or other conditions to capture only what matters.
- Events—Respond to specific occurrences during a test, such as activating equipment when a condition is met (for example, start cooling fans when temperature exceeds a limit).
- Automation APIs—Control and monitor FlexLogger from external applications (Python, NI LabVIEW, or NI TestStand), enabling integration into larger automated test systems.
- Calculation channels—Perform real-time math on acquired data (averages, RMS, custom formulas) to track derived measurements as the test runs.
- Plug-ins—Extend FlexLogger with custom LabVIEW or Python plug-ins to integrate third-party hardware, perform custom analysis, or connect to lab systems.
- CAN/LIN logging—Acquire and log automotive network data alongside sensor measurements for complete vehicle or subsystem testing.
LabVIEW+ Suite (788509-35)NI LabVIEW+ Suite, Subscription License, DownloadRecommended for engineers building full test and validation systems where modular code development and higher-level frameworks are needed to accelerate development for shorter time to market.
The LabVIEW+ Suite includes the following products:
