Time Delay Relays are electronic components designed to perform a variety of time-delay functions. They are used in a wide range of applications, including industrial automation, programmable logic controllers (PLCs), motors, and robotics. The H3YN-21 AC24 is a type of time-delay relay designed to provide a time-delay control of AC24V, DC12V, B6V and B12V circuits.

The H3YN-21 AC24 has a variety of applications, including starting and stopping motor operations, timer-controlled circuits, timed alarm cycles, and time-delay switching. It can also be used to control multiple loads from a single input by providing a two-phase time-delay operation. In addition, the H3YN-21 AC24 can be used in automated systems to provide an efficient way of controlling the on/off timing of a process.

The working principle of the H3YN-21 AC24 involves the electrical contact points being energized by an input voltage and current. When the input voltage reaches a certain threshold, the relay will activate and cause the contact points to close, allowing the current to pass through. The contact points will then remain closed until the preset time delay has elapsed and the current is no longer present. This allows the user to control the on/off timing of a process or multiple loads from a single input.

The H3YN-21 AC24 also includes a built-in alarm. When activated, the alarm will sound to notify the user that the specified time delay has elapsed. This feature is especially useful in industrial automation systems, where it can be used to detect any changes in the time-delay setting that may have occurred.

The H3YN-21 AC24 is designed to be highly reliable and accurate. It is constructed with solid-state components and is capable of operating in temperatures ranging from -40° C to +85° C. The contact points are designed with low-voltage and current-sinking circuits, and the circuitry is designed to include other advanced features, such as temperature compensation, resistance measurement, and a short-circuit protection.

The H3YN-21 AC24 is a versatile and reliable time delay relay that can be used in a wide range of applications. It is designed to provide a reliable and accurate time-delay control of AC24V, DC12V, B6V, and B12V circuits. It includes a built-in alarm, and its contact points are designed to be low-voltage and current-sinking. Additionally, the circuitry is designed to include advanced features, such as temperature compensation, resistance measurement, and short-circuit protection, making the H3YN-21 AC24 a reliable and versatile time delay relay.
