National Instruments 780181-01 C Series Voltage Input Module
The National Instruments 780181-01 (NI-9239) is a four-channel C Series voltage input module designed for precise differential voltage measurements. It features four female BNC connectors and provides 24-bit resolution, a ±10 V input range, and a maximum sampling rate of 50 kS/s per channel. All four channels can be sampled simultaneously, providing synchronized measurements for applications where timing between signals is important. The module also provides 60 VDC channel-to-channel isolation to help protect connected equipment and measurement systems from voltage differences and transients.
The 780181-01 is designed for use with NI CompactDAQ and CompactRIO systems. Its BNC connections provide a convenient interface for standard coaxial cables and shielded sensors, making it well suited for laboratory, test, and industrial measurement setups. The module is enclosed but does not have a conformal coating. The unit is supplied with the module and its safety, environmental, and regulatory documentation; screws and terminal plugs are not included.
The differential inputs help reduce the effects of common-mode noise and ground-loop errors, making the module suitable for measurements where signal integrity is important. The combination of 24-bit resolution, 50 kS/s per-channel sampling, and channel-to-channel isolation allows the 780181-01 to capture dynamic signals accurately while accommodating systems with different ground references.
Typical applications include automated test equipment, power monitoring, data logging, sensor measurement, actuator testing, and real-time control. Simultaneous sampling keeps the four input channels synchronized and phase-coherent, which is particularly useful when comparing multiple signals or analyzing relationships between channels. When installed in a CompactDAQ or CompactRIO chassis, the 780181-01 can also be combined with other C Series modules to create a mixed-signal measurement system.
