Operation and Functionality

Timing Function: Bp – OFF-delay

The FCT18-BP operates with an OFF-delay timing function, which works as follows:

• When input voltage (Un) is applied, the output relay (R) remains inactive.
• When the control input is triggered, the output relay activates immediately.
• When the control input is deactivated, the timing cycle (T) begins.
• The relay remains activated for the duration of the preset time (T).
• After time T elapses, the relay returns to its inactive state.
• If the control input is reactivated during timing, the timer resets and starts a new cycle when the control input is deactivated again.

Time Setting Configuration

The FCT18-BP offers exceptional flexibility with 10 selectable time ranges:

• 0.1-1s: For rapid cycling applications requiring sub-second precision
• 1-10s: Ideal for standard automation sequences
• 0.1-1m: Short-duration minute-range timing
• 1-10m: Medium-duration minute-range timing
• 0.1-1hr: Hour-range timing for longer processes
• 1-10hr: Extended hour-range timing
• 0.1-1day: Day-range timing for daily cycles
• 1-10day: Extended day-range timing
• 3-30day: Month-range timing
• 10-100day: Long-term timing for extended processes

Time setting is performed using the rotary dial on the front face of the relay. First, select the appropriate time range, then fine-tune the specific time value within that range using the ratio setting dial, which provides adjustment from 10% to 100% of the selected range in 5% increments.

تنظیم نسبت

The ratio setting dial allows for precise adjustment within the selected time range, offering settings from 10% to 100% in 5% increments (10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 100%). This combination of range selection and ratio setting provides exceptional precision across all timing requirements.

نصب و سیم کشی

The FCT18-BP features straightforward installation on standard 35mm DIN rails (EN/IEC 60715) with a compact footprint of only 90mm×18mm×64mm, making it ideal for space-constrained control panels.

Wiring Connections

The relay features clearly labeled terminals:

• A1-A2: Power supply input terminals

FAQs About the FCT18-BP Interval Timer Relay

What is the difference between an interval timer relay and a standard timer relay?

An interval timer relay like the FCT18-BP specifically manages the timing between operational states, allowing precise control over how long a device remains activated after a trigger event. The OFF-delay function keeps the output relay energized for a preset time after the control signal is removed, which is particularly useful for applications requiring continued operation after the initiating signal ends.

Can the FCT18-BP be used in outdoor applications?

The FCT18-BP has an IP20 protection rating, making it suitable for indoor installation within appropriate enclosures. For outdoor applications, the relay must be installed within a weatherproof control panel or enclosure that provides adequate protection against moisture, dust, and temperature extremes.

What is the expected lifespan of the FCT18-BP?

The FCT18-BP is built for long-term reliability with a mechanical life of 10 million operations and an electrical life of 100,000 operations at rated load. This translates to many years of service in most industrial applications, particularly when operated within specified electrical and environmental parameters.

How accurate is the timing function across different temperature ranges?

The FCT18-BP maintains excellent timing accuracy across its operational temperature range, with a temperature coefficient of just 0.05%/°C referenced to 20°C. This means timing precision is minimally affected by temperature fluctuations, making it reliable even in environments with variable thermal conditions.

Can the FCT18-BP be used with both AC and DC control circuits?

Yes, the FCT18-BP with the “W” voltage designation is designed to work with both AC and DC power supplies from 12V to 240V, making it exceptionally versatile for integration with various control system types without requiring separate models for different voltage systems.
