Time Delay Relays are a type of automatic control switch which can be used to delay the operation of a controller for a predetermined period of time. The H3YN-4 AC24 is a modern-day model of such a relay.

The H3YN-4 AC24 includes two circuits, one that triggers the sequence and another that outputs a signal to the control device. It is somewhat similar to a timer in that the circuit starts and ends at certain predetermined intervals without any manual intervention. Its most basic function is to provide a time-delay output and in some cases, it is used to sense the presence of an element such as a pressure switch or a resistive sensor. It can also be used to to provide the safety and system signals necessary for certain industrial operations.

This particular model has a rated voltage of 200VAC, a rated current of 24VAC, a time delay range of 0.1-30 seconds, and a temperature range of -20°C to +55°C. It also includes a green LED light that functions as a living indicator when the circuit is energized. The H3YN-4 AC24 has two operation modes – momentary and latching. In momentary operation mode, when an output signal is sent to the control circuit, the time-delay output signal is triggered to begin. This will allow the output signal to finish and then for the time-delay output signal to end in the specified time frame. In latching operation mode, the time-delay will continue until the output signal is turned off. The main working principle behind the H3YN-4 AC24 is that when a set time delay is initiated, the output signal generated will be of a fixed duration. This output signal will then send a signal to the control circuit, starting the process of activating the desired controller. It is often used in various applications, such as circuits that require a time-delay before they are energized, circuit breakers to interrupt a power source and de-energize any associated equipment, and emergency power off (EPO) circuits that disconnect a device or machine from the power source after a desired time delay.

In addition, the H3YN-4 AC24 provides both output protection and circuit safety, making it an attractive device for a wide range of industrial applications. It is also easy to install and use, making it a suitable choice for both the novice and expert alike. This is one of the reasons why the H3YN-4 AC24 has become so popular over the years and is a staple part of many industrial installations.
