Industrial Application Scenarios
The FCT18-BR single interval relay excels in scenarios where controlled timing intervals initiated by control signals are critical. Below are key applications where its functionality delivers superior performance:
Warning Light Systems
Activates warning lights for a preset period when triggered by a sensor or control signal, ensuring safety alerts are clearly visible.
Key Benefits:
- Ensures critical warnings remain visible for required duration
- Automatically resets for subsequent alerts
- Reduces energy consumption compared to continuous operation
Conveyor Processing
Controls processing time for items on a conveyor, activating equipment for a fixed interval after sensor detection.
Key Benefits:
- Ensures consistent processing time for each item
- Automatically resets for next item
- Improves production quality and consistency
Safety Lockout Systems
Maintains safety locks for a preset period after activation, preventing accidental access to hazardous areas.
Key Benefits:
- Enforces mandatory safety lockout periods
- Automatically releases after set interval
- Compliant with industrial safety standards
Chemical Dosing Systems
Activates chemical injection pumps for a precise interval when triggered by process sensors, ensuring accurate dosing.
Key Benefits:
- Ensures precise chemical quantities
- Automatically stops after set interval
- Reduces waste and improves process consistency
Ventilation Control
Activates ventilation systems for a preset time when triggered by air quality sensors, maintaining safe working conditions.
Key Benefits:
- Ensures adequate ventilation after contamination events
- Automatically shuts down after required interval
- Reduces energy consumption
Automated Testing
Controls test equipment activation for precise intervals when triggered by product sensors, ensuring consistent testing procedures.
Key Benefits:
- Ensures consistent test durations
- Automatically resets for next test cycle
- Improves product quality and reliability
Timing Sequence
Timing Operation:
- Control signal (S) applied – output (R) closes and timing starts
- After preset time (T) – output (R) opens
- Output remains open until next control signal (S) is applied
- Control signal can be shorter or longer than T
