Function and Working Principle
The NFAI543-S00/A4500 receives digital output commands from the Yokogawa controller and converts them into standard 4–20 mA analog current signals for controlling field instruments.
Each output channel operates independently with electrical isolation, ensuring accurate signal transmission while minimizing electrical interference between channels.
Operating Sequence
- The controller generates a digital control command.
- The module receives the digital data.
- Internal D/A converters convert the digital value into a 4–20 mA output signal.
- The analog signal is transmitted to the connected field device.
- The field device adjusts its operation according to the received control signal.
Key Features
- 16 isolated analog output channels
- Standard 4–20 mA current output
