Function and Working Principle
The NFDV561 receives digital output commands from the Yokogawa controller and converts them into discrete electrical signals that control connected field equipment.
Each output channel operates independently, allowing the module to switch external devices according to the control program executed by the CPU. Electrical isolation protects both the controller and connected equipment from electrical interference and faults.
Operating Sequence
- The controller executes the automation program.
- Digital output commands are transmitted to the NFDV561.
- The corresponding output channels switch ON or OFF.
- Connected field devices receive the control signals.
- Process equipment performs the required control operation.
Key Features
- High-reliability digital output module
