Product Description
The National Instruments C Series Voltage and Current Input Module, with part numbers 781068-01, 785040-01, 781068-02, and 199272C-01L, offers a versatile solution for data acquisition, featuring 16 analog input channels that support a voltage range of ±10.2 V and a current range of ±21.5 mA.
Designed to deliver precise measurements, the module boasts a high resolution of 52 ms and a high-speed mode of 2 ms, accommodating rapid changes in signal with ease. The voltage input impedance is greater than 1 GΩ, ensuring minimal loading on the measured circuit, while the current input impedance is around 85 Ω, suitable for most sensing applications.
Compatibility with CompactDAQ and CompactRIO platforms makes integration seamless for a variety of systems, and a maximum sample rate of 500 samples per second (S/s) enables timely data collection. Inclusion of 50/60 Hz noise rejection significantly improves signal quality in noisy industrial environments.
Connection options include a standard 37-pin DSUB and a 36-pin spring terminal, offering flexibility for wiring, which can accommodate a wire gauge range from 26 AWG to 16 AWG. The module is also designed for durability, with weights of 5.7 oz for the spring terminal version and 5.1 oz for the DSUB version, indicative of its solid construction.
