Understanding ON-delay (Rising Edge Triggering)

The FCT18-AdR’s timing function utilizes ON-delay with rising edge triggering, providing precise control over when your connected equipment activates. The timing diagram illustrates how this works:

1. When the input voltage (Un) is applied, the unit is powered
2. When the control signal (S) rises from low to high, the timing sequence begins
3. After the set delay period (T1), the relay (R) is activated
4. The relay remains active until the set operational time (T2) elapses
5. This sequence repeats with each rising edge of the control signal

This functionality makes the FCT18-AdR ideal for applications requiring precise timing after a trigger event, such as sequential machine operations, delayed start processes, or time-controlled cycling.

Comprehensive Time Range Options

The FCT18-AdR offers exceptional versatility with its wide range of time settings:

Time Range	Application Examples
0.1-1s	Fast process control, quick cycling operations
1-10s	Short delay sequences, brief equipment pauses
0.1-1m	Timed process stages, short cooldown periods
1-10m	Extended processing operations, material curing
0.1-1hr	Production cycle timing, equipment warm-up
1-10hr	Long industrial processes, extended operations
0.1-1day	Day-long timing sequences, overnight operations
1-10day	Multi-day processing, extended monitoring
3-30day	Monthly maintenance timing, long-term processes
10-100day	Quarterly operations, extended monitoring cycles

Each time range is easily selectable via the intuitive dial interface, and the precise timing within each range can be fine-tuned using the ratio setting dial, providing 19 adjustment points from 10% to 100% of the selected range.
