Product Overview

The 1794-IJ2XT is an Allen-Bradley Flex I/O-XT 2-point high-resolution frequency input module within the Flex XT I/O system. It acquires frequency signals and provides two isolated output channels for use in control systems that monitor and react to rotational or pulse-based sensors, such as encoders or flowmeters. The module interfaces with a 24 V DC isolated customer-supplied output supply, integrates into Flex I/O racks on DIN rails, and is suited for industrial installations requiring precise speed or flow feedback. Part number 1794-IJ2XT.
