Allen-Bradley 1794-IE4XOE2 Flex I/O combination analog I/O module is a versatile and high-performance device from the Rockwell Automation Flex I/O 1794 series, designed for precise analog signal measurement and control in industrial automation systems. The module features four single-ended, non-isolated analog input channels configurable for current signals of 0–20 mA and 4–20 mA, and voltage signals of ±10V DC and 0–10V DC. It also provides two single-ended, non-isolated analog output channels configurable for 0–20 mA, 4–20 mA, and ±10V DC output signals. The 1794-IE4XOE2 module requires use with Flex I/O terminal base units, including 1794-TB2, 1794-TB3, 1794-TB3S, 1794-TB3T, and 1794-TB3TS, ensuring secure installation and reliable system integration.
