Time Delay Relays are a type of electrical switch which operates at a set time interval after a current or voltage signal passes through them. They provide various types of control functionality, such as providing a delay in the operation of a circuit, activating a circuit breaker that breaks a circuit, regulating the speed of electric motors and similar applications. 4-1472973-4 is an example of a Time Delay Relay.

The 4-1472973-4 is a versatile Time Delay Relay which can be used for a variety of different applications. It has a wide input voltage range from 12 volts DC to 110 volts AC, and is capable of providing up to 4 change-over contacts. It has a selectable delay range from 0.1 second to 1 hour and a selectable repeat cycle time from 0.2 second to 10 minutes. It also has many safety features such as an auto-reset time delay, LED operating indicators and short circuit protection.

The working principle of 4-1472973-4 Time Delay Relays is fairly simple. It works by sensing the input current or voltage signal and then sending a relay signal to an output terminal. This relay signal causes the contacts of the relay to open or close, depending on the desired response. These contacts then either make or break the circuit, depending on their state. The advantage of using this type of relay lies in its accuracy, as it is designed to only activate or deactivate the output contacts after a specific time period, eliminating any possibility of incorrect operation.

As mentioned, 4-1472973-4 Time Delay Relays can be used for a variety of applications. In its simplest form, it can be used to delay the operation of a circuit, for example to keep lights on for a set period after the circuit has been switched off. When used in conjunction with motor speed controllers, the device can be used to regulate the speed of the motor, ensuring that it only reaches its maximum speed after a certain time period. The device is also commonly used in industrial and commercial settings to control safety mechanisms, such as fire alarms, sprinkler systems and other safety-related applications. It can also be used in automatic door closer systems, so that they only close when a certain period of time has passed.

The 4-1472973-4 Time Delay Relay is a versatile and reliable device which can be used for a variety of applications. Its accuracy and safety features make it an ideal choice for a wide range of applications, from safety to operating motor speed controllers. Its wide input voltage range and selectable delay range make it a very flexible device, allowing for a wide range of applications and ensuring that it will perform reliably in any situation.
