Time Delay Relays are versatile electronic components used to control open and close times of machines and electrical circuits.
LT4H8-AC240V is one type of time delay relay which is available in a wide variety of applications and fields.
It functions by opening or closing an electrical circuit after a certain time delay, thus enabling it to act as a timer or delay device to regulate the flow of current.

Application Field

The LT4H8-AC240V time delay relay comes in a variety of application fields where its maximum voltage is up to 240 volts. These include compressors for cooling and air conditioning systems, lights, pumps, air conditioning, and robots. Additionally, its application field is continually expanding as new uses for it are being found in increasingly more complex industrial and household settings.

Working Principle

The LT4H8-AC240V is a general-purpose time delay relay with a normally open contact that closes "instantaneously" when power is connected. It then keeps the contact closed for a set amount of time, after which it will reopen, thus turning off the circuit. The amount of time the contact remains closed is regulated by the user and can be adjusted to as little as one second. This time delay feature makes the LT4H8-AC240V an ideal component in applications which requires a delay before turning off or restarting a machine or circuit.

The LT4H8-AC240V contains a spring that allows it to open and close based on the amount of voltage used and the amount of time elapsed. It also contains two blocks of metal which come together when the voltage is applied, thus allowing current to flow. Once the set time delay has expired, the blocks of metal separate and the current stops, thus turning the circuit off.

The time delay relay has different standby times and different protective functions, depending on the user\'s requirements. This includes protections against inrush currents, short-circuit protection, overvoltage protection, and over-temperature protection. Furthermore, the device is also equipped with protective features for both high and low temperatures.

The LT4H8-AC240V time delay relay is a versatile component that can be used in a variety of applications. Its adjustable time delay setting allows it to act as a timer or delay device, thus regulating the flow of current in an array of scenarios. It is also equipped with various protective features, making it a safe and efficient way to control open and close times of machines and electrical circuits.
