PLC 1794-OE4XT XT 4-Channel Analog Output Module

1794-OE4XT is a four-channel analog output module that sends voltage or current control signals from a compatible 1794 distributed I/O station to field devices. Its terminal base, 24 V DC field supply, output mode, load and controller configuration must match the installed system.

1794-OE4XT provides four single-ended, non-isolated analog outputs. The configured voltage or current mode and the connected load must be verified for every channel before commissioning.

1794-OE4XT supports a nominal ±10 V voltage range and a maximum 0–20 mA current range. The selected controller data format, field wiring and load must be compatible with the chosen output mode.

1794-OE4XT is documented for 1794-TB2, 1794-TB3, 1794-TB3S, 1794-TB3T, 1794-TB3TS or 1794-TBN terminal bases. Confirm the installed base, keyswitch position 4 and terminal wiring before replacement.

1794-OE4XT has four single-ended, non-isolated outputs, so it should not be treated as a channel-to-channel isolated module. Grounding, common references, field supply and load connections must follow the official wiring instructions.

1794-OE4XT is listed with an end-of-life status and a planned discontinuation date of 28 February 2027; the official functional replacement is 5094-OF8XT. A migration still requires verification of the terminal base, wiring, controller project, output configuration and physical system architecture.

For 1794-OE4XT, provide the exact catalog number, quantity, terminal-base model, voltage or current mode, connected load, 24 V DC supply, controller model and project revision, installation environment and delivery destination.
