6. Does the system provide diagnostic information for maintenance?
   Yes, it continuously monitors sensor health, circuit integrity, and reports faults to reduce false trips and maintenance downtime.

7. Is the module suitable for SIL-rated safety systems?
   Yes, the 3300/53 Overspeed Protection System is SIL 2 certified, meeting international safety integrity standards.

8. How accurate is the speed measurement and trip detection?
   The system provides ±0.5% full-scale speed accuracy across its operational range.

9. Can the module operate reliably in harsh environmental conditions?
   Yes, it operates from -40°C to +85°C and 0–95% relative humidity, ensuring reliability in extreme industrial environments.

10. Can multiple 3300/53 modules be networked for complex machinery?
    Yes, multiple modules can operate in parallel to provide coordinated overspeed protection across machinery trains.
