CompactRIO systems provide high-performance processing capabilities, sensor-specific conditioned I/O, and a closely integrated software toolchain that make them ideal for Industrial Internet of Things (IIoT), monitoring, and control applications.

Hetrogeneous Architecture

CompactRIO Controllers feature a hetetrogeneous architecture with two processing targets.

  1.  Real-time processor for communicatiion and signal processing  
  2.  FPGA for implementing  high-speed control, custom timing and triggering, and signal processing directly in hardware.

Combines customizable software with powerful processing and I/O for any measurement, control, or monitoring application.

Connects to many sensors and buses and support measurements such as temperature, voltage, resistance, audio frequency, and more.

Extensive I/O

Eliminate the need for separate subsystems by connecting components – like motors, cameras, and HMIs – directly to your CompactRIO Controllers with built-in I/O such as Gigabit Ethernet, serial and USB ports and slots for upto eight I/O Modues for measurements-specific signal conditioning.
