Understanding OFF-Delay Function

The FCT18-Q operates with triple OFF-delay (rising edge triggering) functionality. During the delay processing period, the signal will be considered invalid. Here’s how it works:

1. When the input signal (Un) is applied, the relay output (R) remains active
2. The timing function is triggered by the rising edge of the input signal (S)
3. When the input signal is removed, the relay maintains its state for the preset time period (T1+T2)
4. After the delay period expires, the relay returns to its original state

This timing function is particularly useful for applications where equipment needs to continue operating for a specific period after the trigger signal has been removed, such as fans continuing to run after a machine is powered off to allow for cooling.

وقت کی ترتیب کے اختیارات

The FCT18-Q provides an exceptionally broad range of time settings through its intuitive dial selector system. The available time ranges include:

• 0.1-1 second
• 1-10 seconds
• 0.1-1 minute
• 1-10 minutes
• 0.1-1 hour
• 1-10 hours
• 0.1-1 day
• 1-10 days
• 3-30 days
• 10-100 days

Each range is easily selected using the clearly marked rotary dials on the front of the unit, allowing for precise control over your timing requirements from sub-second intervals to multi-month durations.

Ratio Setting Flexibility

The FCT18-Q features fine-tuning capabilities with its ratio setting dial, allowing you to select the exact percentage of the maximum time range. The available ratio settings include:

This precision adjustment allows you to dial in exactly the timing requirements your application demands without compromising accuracy.
