Understanding the FCT18-BR Timing Function
The FCT18-BR operates with an OFF-delay function with rising edge triggering (BR). This specific timing mode works as follows:
- When power (Un) is applied, the relay remains inactive
- When the control signal (S) is applied (rising edge), the relay (R) activates immediately
- When the control signal (S) is removed, the relay (R) remains activated for the preset time interval (T)
- After the time interval (T) elapses, the relay deactivates
- If the control signal is reapplied during the time interval, the timing sequence restarts
This timing pattern makes the FCT18-BR ideal for applications requiring extended operation after a trigger event has ended.
