Working Principle:
Digital control values from the controller are converted to precise analog signals by the DAC. Output amplifiers drive the field devices, while protection circuits safeguard against faults.
Installation Requirements:
- Connect to appropriate terminal base.
- Use shielded cables for output signals.
- Configure output ranges and safe states in software.
Usage Precautions:
- Verify load impedance matches output specifications.
- Configure safe states to prevent hazardous conditions.
- Test outputs before connecting to field devices.
- Monitor for output fault diagnostics.
