50 kS/s/ch, ±20 mA, 24-Bit, 8-Channel C Series Current Input Module—The NI-9253 is an 8-channel analog input module for ComapctDAQ and CompactRIO systems. Each channel provides a ±20 mA input range and 24 bits of resolution at a 50 kS/s sample rate. The NI-9253 has several diagnostic features to ensure your system is operating nominally at all times with open channel detection, power supply detection, and configurable thresholds. The NI-9253 has eight LEDs to indicate the status of each channel and the power supply so that a user in the field can easily validate that the system is operating normally. The NI-9253 also features a number of programmable hardware filters. By choosing the specific Butterworth and comb filters for your application, you can significantly reduce the noise in your system.
