Function and Working Principle
The MC-TDOD13 acts as an interface layer between the control system and field output devices:
- Control system generates digital output commands.
- Signals are routed to the FTA module.
- The module distributes outputs to individual field wiring terminals.
- Each channel drives external devices such as valves, relays, or alarms.
- Electrical isolation protects the control system from field-side disturbances.
This structure ensures safe, organized, and reliable output signal distribution.
