ISOLATED SIGNAL OUTPUT / FLEX I/O
1794-OF4I
4-Point Isolated Analog Output Module
Four channels. Two signal families.
The 1794-OF4I converts controller output data into analog signals for field devices. Its four isolated channels can be used for voltage or current output, making it relevant to applications such as command references, valve position control and other analog setpoints when the field device matches the selected range.
Use this module when separate analog output channels and channel-to-channel isolation are important to the system design. Confirm the signal type, load and terminal base before replacement.

|
CHANNELS / 01
4 Isolated
Four analog output points with channel isolation. Verify the terminal base and wiring arrangement used by the installed unit.
|
OUTPUT / 02
±10 V
Voltage output range. Match the selected range to the receiving device and the configured controller data.
|
OUTPUT / 03
0–20 mA
Current output range. Check the loop wiring and device input requirements before applying power.
|
Additional technical points: 15 bit + sign output resolution; 2.5/5.0 ms output conversion rate; 24 V DC supply rating. Performance depends on the selected range, load, terminal base and installation conditions.
REPLACEMENT CHECK
Match the signal before matching the part number.
Tell us whether your application uses voltage or current output, the existing terminal base, the required quantity and the destination. This helps focus the inquiry on the correct configuration rather than just a similar-looking module.

ANALOG OUTPUT
1794-OF4I
Four isolated analog output channels for voltage or current signals. Use it when the controller must command an analog field device.
|
ANALOG INPUT
1794-IF4I
An input module serves the opposite signal direction: it acquires analog values from field devices rather than generating output commands. Verify exact channel and range requirements.
|
MIXED I/O
1794-IF2XOF2I
A combined input/output design can suit applications needing both signal directions in one module. It is not a one-for-one substitute for four isolated outputs.
|
System fit: the 1794-OF4I is part of the FLEX I/O family. Select compatible terminal-base hardware and verify channel wiring, output range, load and controller configuration as a complete assembly.

BUYER'S CHECKPOINTS
1794-OF4I — Frequently Asked Questions
1. Can 1794-OF4I drive a 4–20 mA field device?
The listed current output range is 0–20 mA. Confirm the receiving device's required range and the channel configuration before commissioning; a 4–20 mA application must be configured and scaled appropriately.
2. What is the practical difference between 1794-OF4I and 1794-OE4?
The 1794-OF4I is a four-point isolated analog output module. The 1794-OE4 is a different FLEX I/O output model; verify isolation, signal range, terminal base and application requirements rather than treating the model numbers as interchangeable.
3. Does 1794-OF4I support both voltage and current signals?
Yes. The module supports ±10 V voltage output and 0–20 mA current output. Select the range and data format for each channel to match the controlled device and controller program.
4. What should be checked if a 1794-OF4I output does not match the commanded value?
Check the channel's selected range and data format, controller scaling, field wiring, load conditions and the module's status. Also confirm the terminal-base arrangement and the system's 24 V DC supply.
5. What details are needed to order a replacement 1794-OF4I?
Provide the complete catalog number and series from the label, the terminal-base model, output signal type, quantity and destination. If possible, include a photo of the installed unit to help verify the configuration.
RETURNS / REPLACEMENT
Contact us within 7 days after delivery if a problem arises. Items returned for review should be in original condition, and the reason for return must be stated clearly. A return or replacement is arranged after receipt and inspection. The buyer covers return shipping costs.
