Function and Working Principle
The MC-TDOD14 acts as an interface layer between the control system and field devices:
- The control system generates digital output commands.
- These signals are routed to the FTA module.
- The module distributes signals to individual field terminals.
- Each channel drives external devices such as valves, relays, or alarms.
- Electrical isolation protects the control system from field-side disturbances.
This ensures safe, organized, and reliable signal transmission.
