Off Delay Timer Wiring Diagram

Off delay timers are an essential component of many electrical systems. They are used to delay the operation of a circuit or device after an input signal has been removed. This article will provide a comprehensive guide to off delay timer wiring diagram, including the basic concept, application, and practical example.

What is an Off Delay Timer?

An off delay timer is an electrical device that provides a delay between the removal of an input signal and the deactivation of the output signal. It is used in many applications where it is necessary to delay the operation of a device or circuit after an input signal has been removed. The off delay timer is commonly used in industrial control systems, HVAC systems, and lighting control systems.

The off delay timer consists of several components, including a control circuit, a timing circuit, and an output circuit. The control circuit receives the input signal and triggers the timing circuit. The timing circuit then starts a countdown timer, and when the timer reaches zero, the output signal is deactivated. The off delay timer can be programmed to provide a delay of several seconds, minutes, or hours, depending on the application requirement.

Off Delay Timer Wiring Diagram

The off delay timer wiring diagram is relatively simple. It involves connecting the control circuit, timing circuit, and output circuit in series. The control circuit is connected to the input signal, which triggers the timing circuit. The timing circuit is connected to the output circuit, which is used to control the device or circuit being delayed. The wiring diagram is typically provided by the timer manufacturer and should be followed closely to ensure proper operation of the device.

The off delay timer can be wired in several ways, depending on the application. The most common wiring configuration is the Normally Open Off Delay (NOOD) configuration. In this configuration, the timer is normally open, and the output signal is inactive. When the input signal is received, the timer is triggered, and the output signal is activated. When the input signal is removed, the timer starts counting down, and the output signal is deactivated when the timer reaches zero.

Another common wiring configuration is the Normally Closed Off Delay (NCOD) configuration. In this configuration, the timer is normally closed, and the output signal is active. When the input signal is received, the timer is triggered, and the output signal is deactivated. When the input signal is removed, the timer starts counting down, and the output signal is activated when the timer reaches zero.
