Time Delay Relays are electrical relays with an electronic timer installed inside of them. The timer can be set to delay the relay from engaging the circuit, or delaying the de-activation of the relay, or both. This allows complex automation and control scenarios to be achieved without the need for manual input. The most commonly used type of time delay relay is the H3JA-8A AC100-120 3M.

The H3JA-8A AC100-120 3M time delay relay is a multi-function unit and can be used to accomplish a variety of tasks. It features a control input that will start the timer; the time period is adjustable and the device will stay active for the programmed duration before cutting off. The relay has a manual reset capability that must be manually operated to reset the time delay. This is beneficial in applications where periodic operation is required, but manual resetting is not necessarily desired.

The H3JA-8A AC100-120 3M time delay relay also features a power input that will cause the relay to energize immediately, without waiting for the timer to start. This feature can be used when an individual momentary switch closes or opens a circuit. The time delay functionality of this device allows a connection or disconnection to be made after a set time period, making it ideal for applications that require the power to stay on until the set time has passed. For example, this time delay relay is used in applications such as automobiles, cranes, assembly lines, and elevators, where timing needs to be accurate.

The H3JA-8A AC100-120 3M time delay relay also features an adjustable time delay. This means the user can set the timer to wait for a certain amount of time before the contact closes, allowing for accurate timing in applications such as motor control, on/off control of lights, and other similar electrical systems that require a delay to happen before the device is engaged. This offers users flexibility when setting up automated events.

The working principle of the H3JA-8A AC100-120 3M time delay relay is simple, yet highly effective. When power is applied to the relay, the timer starts counting down from the set time. Once the set time has elapsed, the relay will then energize the contact, thus engaging the circuit. Depending on the model, the contact will either stay energized until the reset button is pressed or will return to its original state at the end of the set time period.

The H3JA-8A AC100-120 3M time delay relay is highly versatile and can be used in a variety of applications. It is typically used in industrial settings, but can also be found in residential applications as well. Its accuracy and ease of use have made it a popular choice for many automation projects. Whether it is used in an industrial setting or for a home automation project, the H3JA-8A AC100-120 3M time delay relay is sure to provide the desired results.
