H3DS-AL AC24-230/DC24-48 application field and working principle

Time Delay Relays are relays with a time delay. They have an adjustable time delay function that typically provides a delay of up to five minutes. Time Delay Relays are primarily used to delay the starting and stopping of motors, widely used in automatic control systems.The H3DS-AL AC24-230/DC24-48 Time Delay Relay is an excellent choice for applications that require an adjustable time delay. It features an integrated mini voltage regulator, allowing it to be connected to a wide range of voltage sources. The integrated voltage regulator also helps to protect the system from voltage spikes and other power disturbances.The H3DS-AL AC24-230/DC24-48 Time Delay Relay features a wide range of adjustable time settings, from 0.05 to 5 minutes. It also features a low power consumption design, and is capable of operating in extreme temperature environments. The H3DS-AL AC24-230/DC24-48 also has an extended service life, typically rated at 5,000,000 cycles.Regarding its application field, the H3DS-AL AC24-230/DC24-48 Time Delay Relay can be used for applications that require a delay in starting or stopping motors, such as conveyor systems, door openers, and other applications in the industrial and consumer markets.Now, let’s discuss the working principle of the H3DS-AL AC24-230/DC24-48 Time Delay Relay. The relay operates on the principle of electromagnetism. It works by passing a current through a coil, creating an electromagnet. This electromagnet is connected to the relay’s armature, which is a switch that is connected to the power supply. When the relay is triggered, the electromagnet pulls on the armature, closing the switch and allowing current to pass through the relay.When the current is passed through the relay, it triggers the timer, which controls the duration of the time delay. This is done by a resistor that is connected in series with the relay coil. The resistor starts to charge when the current flows through it, creating an adjustable voltage drop across the system. Once the timer reaches its set time, the voltage drop causes the relay to de-energize, and the circuit opens, stopping the current flow.In summary, the H3DS-AL AC24-230/DC24-48 Time Delay Relay is an excellent choice for applications that require an adjustable time delay. It features a wide range of adjustable time settings, is capable of operating in extreme temperature environments, and has a low power consumption design. The relay operates on the principle of electromagnetism, wherein an electromagnet is connected to the relay’s armature, and an adjustable timer is used to control the duration of the time delay. This device can be used for applications that require a delay in starting or stopping motors, such as conveyor systems, door openers, and other applications in the industrial and consumer markets.
