VIOX FCT18-AP Power On-Delay Timer Relay

Panimula

The VIOX FCT18-AP is a high-precision power on-delay timer relay designed for industrial automation and control systems where reliable timing functions are critical. This compact DIN rail-mounted device provides exceptional timing accuracy and versatility, making it the ideal choice for applications requiring controlled sequential operations, machine startup delays, and process timing control.

With its ON-delay functionality, the FCT18-AP ensures that output contacts only activate after a precisely programmed delay following power application. This capability is essential in preventing system damage, ensuring proper initialization sequences, and coordinating multiple equipment operations in industrial environments.

What is a Power On-Delay Timer Relay?

A power on-delay timer relay is a control device that introduces a deliberate time delay between when power is applied to the relay and when its output contacts change state. This timing function is critical in many industrial applications where equipment needs to start in a specific sequence or where systems require initialization time before engaging connected loads.

In the FCT18-AP relay, once power is applied to terminals A1-A2, the timing cycle begins. The device counts down the preset delay time (indicated by ‘T’ in the timing diagram) before activating the output contacts. This controlled delay provides system protection and ensures proper operational sequences across various industrial applications.

Detailed Timing Function

The FCT18-AP operates with the “Ap: ON-delay” timing function. This means:

1. When input voltage (Un) is applied, the timing cycle (T) begins immediately
2. The output relay (R) remains inactive during the timing period
3. After the preset time has elapsed, the output relay activates
4. The relay remains activated as long as the input voltage is maintained
5. If the input voltage is interrupted before the timing cycle completes, the timer resets
6. When input voltage is removed, the output relay immediately returns to its inactive state

This timing function is ideal for applications requiring equipment to start only after a specific delay following power application, ensuring proper system initialization and sequential operations.
