Introduction to the FCT18-AgR Pulse Delayed Relay

The VIOX FCT18-AgR is a high-performance pulse delayed relay designed for industrial automation systems that require precise timing control. With its ON-delay functionality and rising edge triggering mechanism, this device offers exceptional reliability for critical timing applications across various industries. The FCT18-AgR stands out in the market due to its wide time range settings, versatile power supply options, and robust anti-interference capabilities.

What is a Pulse Delayed Relay?

A pulse delayed relay is a specialized timing device that creates a controlled delay between when an input signal is received and when the output is activated. The FCT18-AgR specifically utilizes ON-delay functionality, meaning that when the trigger signal (Un) is applied, the relay output (R) activates only after a preset delay period has elapsed. This type of timing control is essential in sequential operations, process control, machine startup sequences, and safety applications.

Key Features of the FCT18-AgR Pulse Delayed Relay

Eksepsjonell rekkevidde og nøyaktighet

The FCT18-AgR offers an impressive timing range from 0.1 seconds to 100 days, making it suitable for both rapid-response applications and long-term delay requirements. With ten distinct time setting ranges, including:

• 0,1-1 sekund
• 1-10 sekunder
• 0,1-1 minutt
• 1-10 minutter
• 0,1-1 time
• 1-10 timer
• 0,1-1 dag
• 1-10 dager

This wide range enables precise control for virtually any industrial timing application. The time error is maintained at less than 0.5%, with a time deviation of just 0.1% and repeat accuracy of 0.5%, ensuring consistent and reliable operation in critical timing sequences.

Flexible Ratio Setting

One of the standout features of the FCT18-AgR is its adjustable ratio setting, which allows fine-tuning of the timing duration within each time range. The ratio can be set from 10% to 100% in 5% increments (10%, 15%, 20%, etc.), providing exceptional precision for your specific application requirements.

Allsidige strømforsyningsalternativer

The FCT18-AgR supports a wide power supply range from 12V to 240V AC/DC, making it compatible with virtually any industrial power system. This versatility eliminates the need for additional power conversion components, simplifying installation and reducing overall system complexity. The device features a generous voltage tolerance of -15% to +10%, ensuring stable operation even in environments with fluctuating power conditions.

Tydelige visuelle indikatorer

The FCT18-AgR features intuitive LED indicators for operational status monitoring:

• Grønn LED for indikering av strømtilførsel
• Rød LED for indikasjon av reléstatus

These visual cues allow for quick troubleshooting and status verification at a glance.

How the FCT18-AgR ON-Delay Function Works

The FCT18-AgR operates on a rising edge triggering mechanism, where the timing sequence begins when the input signal (Un) transitions from low to high. During the preset delay period, the signal processing occurs, and the output remains inactive. Once the delay time has elapsed, the relay output (R) activates.

The timing function diagram illustrates this operation:

1. When the input signal (Un) is applied, the delay processing begins
2. The signal (S) is considered invalid during the delay processing period
3. After the preset time (T) elapses, the relay output (R) activates
4. This process repeats for each triggering event

A critical advantage of the FCT18-AgR is that the delay processing is not affected by the signal (S), ensuring consistent timing regardless of signal fluctuations.
