Understanding On-Delay Timer Functionality

The FCT18-P implements an ON-delay timing function with falling edge triggering, which means the timing cycle begins when the input signal transitions from high to low (falling edge). The timing diagram illustrates how the relay operates:

• Un (Power): Represents the power supply to the timer relay
• S (Trigger Signal): The control input that initiates the timing sequence
• R (Relay Output): The relay output status during operation
• T1 & T2: Timing periods where T1 represents the initial timing delay and T2 represents the relay activation period

When power is applied to the timer relay, it remains in standby mode until a control signal is received. Once the control signal transitions from high to low, the timer begins counting (T1 period). After the preset delay time expires, the relay activates (T2 period) and remains active until the next control signal triggers a new timing cycle.

Tùy chọn thiết lập thời gian toàn diện

The FCT18-P offers an extensive range of time settings to accommodate various application requirements. The time setting dial allows for precise configuration within the following ranges:

The selection of the time range is made using the rotary dial on the front of the unit, while fine-tuning within each range is achieved using the ratio setting dial. The ratio setting allows adjustment from 10% to 100% of the selected time range, providing precise control over the timing function.

Flexible Wiring Options

The FCT18-P supports both NPN and PNP control signal configurations, allowing integration with various control systems and sensors:

Cấu hình NPN

In the NPN configuration, the control signal sinks current to ground. This setup is commonly used with NPN transistor outputs or open-collector outputs from PLCs and other control devices.

Cấu hình PNP

In the PNP configuration, the control signal sources current from the positive supply. This setup is typically used with PNP transistor outputs from sensors or PLC output modules.

Both configurations offer connection terminals for:

• OA1 (DC+ / AC L): Positive DC or AC Line connection
• S: Control signal input
• OA2 (DC- / AC N): Negative DC or AC Neutral connection
