Product Overview
The 1797-IE8 is an Allen-Bradley FLEX Ex analog input module in the Flex I/O 1797 family. It provides eight non-isolated single-ended analog input channels, each configurable for current inputs typically 4-20 mA. It integrates into a distributed control system via a Flex I/O terminal base and communicates through adapters (e.g., Ethernet/IP). It is suited for intrinsically safe installations in hazardous industrial environments and is commonly used for process signal monitoring in oil & gas, chemical, and other hazardous-area installations.
