FCT18-Ata On-Delay Relay with Summation Control
Accumulative Timing Control with Retrigger/Restart Functionality
Product Overview
The FCT18-Ata is a specialized on-delay relay with summation control signal functionality. Engineered for industrial automation systems requiring accumulative timing, it provides precise control where timing only accumulates during signal presence. With its compact 18mm DIN rail design and wide operating voltage range (12-240V AC/DC), the FCT18-Ata is the optimal solution for applications requiring intermittent timing accumulation with high precision (±0.1%).

Industrial Application Scenarios
The FCT18-Ata relay with summation control excels in scenarios requiring accumulative timing only during signal presence. Below are key applications where its unique functionality delivers superior performance:
Production Line Cycle Counting
Tracks cumulative operational time of machines only when active, enabling precise maintenance scheduling based on actual usage rather than calendar time.
Key Benefits:
- Accurate maintenance scheduling based on actual usage
- Prevents unnecessary downtime
- Reduces maintenance costs
Energy Usage Monitoring
Accumulates active time for energy-intensive equipment to calculate and optimize energy consumption patterns.
Key Benefits:
- Precise energy usage tracking
- Identifies inefficient equipment operation
- Enables targeted energy-saving measures
Irrigation System Control
Accumulates watering time across multiple cycles to ensure plants receive precise hydration regardless of intermittent operation.
Key Benefits:
- Optimized water usage
- Precise irrigation control
- Adapts to scheduled watering cycles
Batch Processing
Controls cumulative heating/cooling time for materials processed in multiple stages with intermittent operation.
Key Benefits:
- Ensures consistent product quality
- Accurate process timing across interruptions
- Reduces material waste
Equipment Life Tracking
Monitors cumulative operational hours for critical machinery to predict maintenance needs and prevent failures.
Key Benefits:
- Predictive maintenance scheduling
- Extended equipment lifespan
- Reduced unexpected downtime
Ventilation Control
Ensures cumulative ventilation time is met in environments with intermittent occupancy signals.
Key Benefits:
- Maintains air quality standards
- Energy-efficient operation
- Complies with safety regulations
Timing Sequence
Timing Operation:
Control signal (S) applied – accumulation starts
Control signal (S) removed – accumulation pauses
When accumulated time reaches preset time (T) – output closes
