- Four single-ended analog output channels support voltage or current commands.
- Configurable ranges include ±10 V, 0…10 V, 0…20 mA, and 4…20 mA.
- The XT design is rated for operation from -20 to 70 °C.
1794-OE4XT is an Allen-Bradley FLEX I/O XT analog output module designed for distributed industrial control systems.
The module converts controller output data into four field-level voltage or current commands and connects through a compatible FLEX I/O terminal base.
Before installation or replacement, verify the applicable hardware series, terminal base, external field supply, output range, load, wiring, and installed-system requirements.
Availability, condition, price, and shipping time for 1794-OE4XT are confirmed during quotation.

- Use 1794-TB2, 1794-TB3, 1794-TB3S, 1794-TB3T, 1794-TB3TS, or 1794-TBN as the terminal base for 1794-OE4XT.
- Set the terminal-base keyswitch to position 4 and use shielded wiring for the analog signal connections.
- Provide a 10.5…31.2 V DC external supply; the documented 1794-OE4XT supply current is 165 mA at 24 V DC.
- Field-to-system isolation is rated at 50 V continuous.
- The isolation barrier is tested at 850 V AC for 60 seconds.
- The four output channels are not isolated from one another.
- The XT operating-temperature range is -20…70 °C.
- Relative-humidity capability is 5…95% without condensation.
- The open-style module requires installation in a suitable enclosure.
- FLEX I/O voltage-output control loops using 0…10 V or ±10 V commands.
- Industrial current-output loops using 0…20 mA or 4…20 mA commands.
- Distributed I/O installations requiring operation across the documented XT temperature range.
