        • PRODUCT OVERVIEW

          What is this product?

          Allen-Bradley 1794-OE4XT is a four-point analog output module for the FLEX XT I/O system. Rockwell Automation specifies Series B hardware, a nominal 24 V DC external supply with a 10.5–31.2 V DC operating range, 15 mA FlexBus current and keyswitch position 4. The module installs on a documented FLEX terminal base and provides the analog output interface for a remote I/O station. The complete catalog number, series, terminal base, output wiring and connected load must be checked together before replacement or migration.

      Information

      Overview Manuals Wiring Base Fit Migration

      Features:

      • Four analog output channels are provided in the FLEX XT I/O format for operation from -20 to 70 °C in a compatible station.
      • The module uses a 24 V DC nominal external supply, accepts 10.5 to 31.2 V DC and draws 15 mA from the 5 V FLEXBus.
      • Installation uses keyswitch position 4 and one of the officially listed FLEX XT terminal bases, with no channel-to-channel isolation.

      1794-OE4XT is a Series B Allen-Bradley FLEX XT four-point analog output module. It combines extended-temperature service with a compact terminal-base design for distributed I/O stations, and the installation instructions specify 50 V continuous basic insulation from field-side circuits to the system. The complete catalog number, Series B marking, terminal-base selection, external 24 V DC supply and output wiring must be confirmed together before replacement or commissioning.

      Official source: Rockwell Automation 1794-OE4XT Installation Instructions, publication 1794-IN125E-EN-P, June 2024. Verify the supplied module series and terminal-base installation against the current product documentation.
      Allen-Bradley 1794-OE4XT official installation instructions Manuals / Datasheets / Links Important Notice: Other accessories, manuals, cables, calibration data, software, licenses and related items are not included unless listed in the stock item description. All prices are shown in USD.

      Wire the four 1794-OE4XT analog output channels through an approved terminal base and keep the field-side circuits within the installation-instruction limits. The module has 50 V continuous basic insulation to the system but no isolation between individual channels.

      Set the terminal-base keyswitch to position 4 and use an officially listed base: 1794-TB2, 1794-TB3, 1794-TB3S, 1794-TB3T, 1794-TB3TS or 1794-TBN. Confirm the base code and wiring before inserting the module.

      Rockwell Automation places 1794-OE4XT in End of Life with a discontinuation date of 28 February 2027 and identifies 5094-OF8XT as the functional replacement. Because the replacement belongs to FLEX 5000, treat migration as an engineered platform change rather than a drop-in swap.

      Technical notes

      Allen-Bradley 1794-OE4XT is a Series B four-point FLEX XT analog output module that requires 24 V DC nominal external power, 15 mA from the 5 V FlexBus and keyswitch position 4. Rockwell lists 1794-TB2, 1794-TB3, 1794-TB3S, 1794-TB3T, 1794-TB3TS and 1794-TBN terminal bases. Confirm the complete catalog number, series, terminal base, field-power circuit and analog load before exchange. Rockwell lists the product as End of Life with a planned discontinuation date of 28 February 2027 and identifies 5094-OF8XT as the functional replacement, which requires a separately engineered migration review.

      Confirm 1794-OE4XT Series and Terminal Base

      Verify the complete catalog number 1794-OE4XT, the Series B marking and the installed FLEX XT terminal base before ordering. Supply a clear nameplate photograph and confirm the keyed position 4, output wiring and terminal-base code; this prevents substitution with a visually similar FLEX I/O analog module or with the functional replacement 5094-OF8XT without an approved migration plan.

      Information Needed to Quote the 1794-OE4XT

      Please provide quantity, the full catalog and series marking, a legible nameplate photograph, the mating FLEX XT terminal base and the controller or adapter used in the station. Include the destination country and requested delivery date so Moore Automated can confirm the correct Series B four-output module, exact supply scope and shipment schedule.

      • What is the application role of this FLEX XT module?

        It provides four analog output points in a documented FLEX XT I/O station. The required output range, connected load and controller configuration must match the existing application.

      • What must be checked during installation?

        Set the terminal-base keyswitch to position 4, isolate field power, verify the 24 V DC supply and preserve the original channel wiring. Follow publication 1794-IN125E-EN-P.

      • Is 1794-OE4XT still an active Rockwell product?

        Rockwell lists it as End of Life with a planned discontinuation date of 28 February 2027 and identifies 5094-OF8XT as a functional replacement. Availability is confirmed against current Moore Automated stock.
