Digital systems interface with the physical world through sensors, and in the hyper-connected world of the Industrial Internet of Things (IIoT), these connections are growing rapidly. With the CompactRIO platform, you can take advantage of decades of NI leadership and innovation in acquiring high quality signals from any sensor or bus with C Series I/O modules that feature measurement-specific signal conditioning and options for bank and channel-to-channel isolation.
Figure 1. Take advantage of decades of NI leadership and innovation in acquiring high quality signals.
With more than 150 NI and third-party C Series modules for measurement, control, and communication to choose from, you can connect CompactRIO to any sensor, signal, or bus. In addition to built-in signal conditioning, these hot-swappable modules feature numerous options for sensor connectivity including screw-terminal, BNC, and D-sub connections. Furthermore, C Series modules are designed to operate in the harshest of environments – with extended operating temperature ranges of -40 °C to 70 °C (-40 °F to 158 °F), 50 g shock rating, and a variety of international safety, electromagnetic compatibility (EMC), and environmental certifications and ratings using these modules to connect your sensors to CompactRIO is sure to meet your needs. See table 1 for a full list of I/O capabilities available for the CompactRIO platform.
