- Four isolated analog output channels for FLEX I/O systems
- Configurable voltage and current ranges with 15-bit-plus-sign resolution
- Channel-to-channel, channel-to-backplane, and channel-to-power isolation
1794-OF4I is the Allen-Bradley FLEX I/O module for four isolated analog output channels.
Each channel can be configured for the documented current or voltage range, with factory calibration, independent isolation, and selectable update timing.
Before replacement, confirm the terminal base, 24 V DC field power, channel wiring, output mode, scaling, load resistance, update rate, calibration, and controller configuration.
Availability, condition, price, and shipping time for 1794-OF4I are confirmed during quotation.

- Record the voltage or current mode assigned to every channel
- Preserve engineering scaling, update timing and fault behavior
- Restore controller ownership and tag mapping before enabling outputs
- Each output channel is isolated from the other channels
- Current-loop resistance must remain within the available drive capability
- Voltage-output loads must remain within the documented current limit
- Use an approved FLEX I/O terminal base for the installed arrangement
- Compare terminal designations and keying with the wiring drawing
- Verify 24 V DC field power, polarity, shields and loop continuity
- Isolated 4–20 mA and 0–20 mA control loops
- Isolated bipolar and unipolar voltage commands
- Distributed analog-output control in FLEX I/O systems
