Combines common I/O circuitry, including analog and digital I/O, into a single module for CompactRIO systems. The C Series Multifunction I/O Module is a cost-effective, general-purpose I/O module that helps system designers fit more functionality into a single system. The module includes analog input, analog output, and 5 V TTL digital I/O channels.The C Series Multifunction I/O Module includes the NI-DAQmx driver and configuration utility that simplify configuration and measurements. NI-DAQmx supports NI programming environments as well as Python, ANSI C, C#.NET, and MathWorks MATLAB® software..
