Detailed Timing Function Explanation

The FCT18-2T implements an ON-delay function with falling edge triggering, providing precise control over timing sequences. When the input signal (Un) is applied, the timing sequence begins. The operation is visualized through the following sequence:

1. When power (Un) is applied, the timer remains in standby mode.
2. The control signal (S) triggers the timing operation upon activation.
3. Two separate timing channels (T1 and T2) operate independently:
   • 11-14(R1) corresponds to timing channel T1
   • 21-24(R2) corresponds to timing channel T2
4. When the control signal (S) changes state (falling edge), both timing channels begin their respective delay countdowns.
5. Each relay contact switches state after its pre-configured delay time elapses.
6. Multiple trigger signals during operation will restart the timing sequence (retrigger capability).

Configurable Time Settings

The FCT18-2T offers exceptional flexibility with its comprehensive range of time settings. The rotary dials allow for precise configuration of delay times across multiple time scales:

Adjustable Ratio Settings

In addition to time range selection, the FCT18-2T features precision ratio adjustment from 10% to 100% in 5% increments. This allows for fine-tuning the exact timing value within the selected time range, providing exceptional control granularity for your application requirements.
