1794-IE8 Functional Description

The Flex 8 Point Analog Input Module 1794-IE8 Allen-Bradley is an 8-channel analog input module designed for distributed I/O architectures in industrial automation. This versatile module supports multiple signal types including 0-20mA, 4-20mA, ±10VDC, and 0-10VDC inputs, making it compatible with various field instruments and transmitters. The Flex I/O Analog Input Module Rockwell 1794-IE8 features 12-bit resolution in unipolar mode and 11-bit plus sign in bipolar mode, delivering precise measurement capabilities for process control applications.

With a rapid 256μs conversion rate across all channels, the Allen-Bradley 1794-IE8 Flex 8 Point Analog Input Module offers 0.20% full-scale accuracy at 25°C, maintaining stable performance with minimal drift (0.00428%/°C for voltage, 0.00407%/°C for current). The module operates on 10.5-31.2VDC power and requires compatible terminal bases like 1794-TB2 or 1794-TB3 for installation. Its compact design (3.7×2.1×31.8 inches) supports both DIN rail and panel mounting options.

The 1794-IE8 Single Ended Module AB seamlessly integrates with FLEX I/O communication adapters including Ethernet, ControlNet, and Remote I/O variants. Featuring Removal and Insertion Under Power (RIUP) capability, this module allows maintenance without system shutdown. Its robust construction withstands operating temperatures from -20°C to 55°C and vibrations up to 5g (10-500Hz), ensuring reliability in harsh industrial environments.

As part of the FLEX I/O family, the Analog Input Module 1794-IE8 Allen Bradley eliminates the need for additional terminal strips by enabling direct sensor wiring to its terminal base. The module's conformal coating option provides enhanced protection for demanding applications. With its combination of high accuracy, flexible configuration, and rugged design, this analog input module serves as an ideal solution for diverse process measurement and control requirements in modern automation systems.
