Product Overview

The Allen-Bradley 1797-IE8H is a Flex Ex I/O module in the 1797 series, providing eight intrinsically-safe analog input channels with HART protocol compatibility. It mounts on a terminal base within Flex Ex I/O distributed control systems, collecting analog current signals (e.g. 4-20 mA) from hazardous-area field devices. Commonly used in process control, petrochemical, and intrinsically safe hazardous environments, the 1797-IE8H enables field-device monitoring with integrated diagnostics.
