PRODUCT DESCRIPTION
ALLEN BRADLEY 1794-IE12/A - FLEX I/O Analog Input Module
The ALLEN BRADLEY 1794-IE12/A is a high-density FLEX I/O analog input module designed for industrial process control and data acquisition applications. It provides 12 differential input channels for precise measurement of current and voltage signals, integrating seamlessly into distributed control architectures via a FLEX I/O adapter. This module is critical for monitoring process variables such as pressure, temperature, flow, and level within manufacturing, energy management, and environmental control systems.
