Allen-Bradley 1794-IJ2XT Flex I/O frequency input module is a high-performance 2-channel input and 2-channel isolated output module developed by Rockwell Automation for precise signal measurement and control in industrial automation systems. The 1794-IJ2XT module features two input channels, each supporting a maximum input frequency of 1–32 kHz with a sine wave signal, and requires a minimum on-state voltage of 10V. It also provides two isolated outputs with a nominal output voltage of 24V DC, ensuring stable operation and signal integrity. Designed for accurate frequency monitoring within the Flex I/O 1794 platform, this module offers reliable performance in demanding process and motion control applications.
