Function and Working Principle
The ASD143 module receives digital signals from industrial field devices and converts them into data that can be processed by the control system. These signals typically represent machine or process states such as ON/OFF conditions, alarm states, limit positions, or equipment status signals.
The module continuously scans connected input channels and transmits the signal information to the automation controller for monitoring and control purposes.
This enables:
- Reliable digital signal acquisition
- Real-time process status monitoring
- Integration of field devices into control systems
- Stable communication within distributed automation architectures
- Improved process visibility and operational control
