National Instruments Analog Input Module NI9239

The National Instruments (NI) 9239 is a four-channel, 24-bit analog input module designed for use with NI CompactDAQ and CompactRIO systems. Each channel supports a differential input range of ±10 V and offers simultaneous sampling at rates up to 50 kS/s per channel.

Key Features:

• Channels: 4 differential analog input channels

• ADC Resolution: 24 bit

• Sampling Rate: Up to 50 kS/s per channel

• Input Range: ±10 V

• Isolation: Channel-to-channel isolation up to 250 Vrms (screw terminal version) or 60 VDC (BNC version), providing protection against harmful voltage spikes and eliminating ground loop errors

• Connectivity Options: Available with screw terminal or BNC connectors

• Filtering: Incorporates anti-alias filters for improved measurement accuracy

The NI 9239 is engineered for applications requiring high-resolution and high-speed analog measurements, making it suitable for a variety of general-purpose data acquisition tasks.
