Overview
The Yokogawa F3DA04-6R, based on the F3DA04 analog output module, converts digital data into voltage or current signals for output control within the FA-M3 PLC system. It provides four output channels, a 16-bit digital-to-analog converter (DAC), and a channel conversion speed of 2 us. Software configuration supports multiple output ranges and synchronized updates across active channels.

DCS Process Signal Conversion and Output Control
The F3DA04-6R generates analog voltage and current signals from digital values supplied by the FA-M3 controller. Its 16-bit DAC supports configurable output ranges, allowing the module to interface with compatible analog control inputs.
- Voltage output: Supports four selectable ranges, including -10 to 10 V and 0 to 10 V.
- Current output: Supports 4 to 20 mA, 0 to 20 mA, and -20 to 20 mA.
- Synchronous updates: The DACs of all active channels on the same module can update synchronously.
- Output timing: The update time depends on the number of channels updated in one instruction.
- CPU failure response: The output behavior during CPU failure can be configured independently for each channel.
The output terminals share a common negative reference and are not isolated from one another. The digital signal isolation coupler provides isolation between the output terminals and internal circuitry, with a stated withstand rating of 500 VDC for one minute.
Frequently Asked Questions (FAQ)
Q: How many analog output channels does the F3DA04-6R provide?
A: It provides four analog output channels. Each channel supports software-configurable voltage or current output ranges.
Q: Can all four output channels update simultaneously?
A: Yes. The module supports synchronous DAC updates across all active channels. The update time is 2 us plus 2 us multiplied by the number of channels updated.
Q: Are the analog output channels electrically isolated from each other?
A: No. The output terminals share a common negative reference. The specified 500 VDC, one-minute withstand rating applies between the output terminals and internal circuitry, not between individual output channels.
Field Installation Guidelines
- Install the F3DA04-6R in a compatible Yokogawa FA-M3 system and confirm the assigned module position before wiring.
- Verify the external 24 VDC supply polarity and ensure the supply remains within the specified 19.2 to 30 VDC range.
- Select the required voltage or current output range through the supported software configuration before connecting field devices.
- Check the input requirements and allowable load of each connected device. The module specifies minimum load resistance values for voltage outputs and a 600 ohm minimum load for current output.
- Route analog signal wiring separately from high-voltage and high-current conductors to reduce electrical interference.
- Connect cable shields according to the plant grounding design and applicable Yokogawa installation instructions.
- Do not apply an external voltage or current directly to the output terminals.
- Configure the required output behavior for CPU failure and verify the resulting field signal during commissioning.
