      Overview Manuals Common Applications Product Precautions
      FLEX I/O 8 Point Analog Input Module provides the documented interface for its installed Allen-Bradley FLEX I/O system.
      • Consolidates mixed analog measurements in one field I/O position
      • Provides configurable channel interpretation for voltage or current loops
      • Uses the FLEX I/O terminal-base architecture for field termination
      • Supports controlled channel verification during commissioning

      Connects configured current or voltage field loops to the FLEX I/O adapter and controller for process measurement acquisition. The installation uses the manufacturer-specified host position, companion hardware and field/control wiring for the intended industrial application.

      System commissioning includes identity checks, connection verification, controlled energization and functional diagnostics for 1794-IE8.

      Important Notice: Confirm the complete 1794-IE8 marking, approved system arrangement, connection records and controlled functional test before commissioning or replacement.
