E7022BC004

Time Delay Relays are a type of automotive relays, designed to delay for a specified amount of time before opening or closing the connection after a signal is applied. E7022BC004 is a time delay relay from UTC, featuring an industry-standard 8 pin octal plug, with a wide range of programming options, to meet many different types of applications.

The E7022BC004 is typically used to implement time-delay functions in control systems, allowing it to increase system flexibility, reduce complexity and save space.

Application Field of E7022BC004

The E7022BC004 time delay relays are used in a wide range of applications, including automotive, industrial, medical and consumer applications. Here are some typical applications where the E7022BC004 can be used:

• Automatic door openers
• Car wash drying systems
• Air conditioning units
• Medical equipment
• Air conditioning systems
• Industrial processes

For example, an automatic door opener may use a time delay relay to delay opening of the door for a set amount of time. In car washes, a drying system could be set up involving a time delay relay, to ensure that the car is fully dry before the system turns off.

E7022BC004 can also be used in air conditioning systems, for example, to prevent the system from starting up or shutting down too fast, or in medical equipment, to ensure proper functioning. It can also be used in industrial processes, such as machine start-up or shut-down sequences.

Working Principle of E7022BC004

The E7022BC004 time delay relay works by using electronic timing components to switch the relay on or off after a specified period of time. It’s typically used with an external power supply voltage, for example 12V or 24V.

When the power supply voltage is applied, the relay will remain in an OFF state until the delay has finished. At the end of the delay period, the relay will switch to an ON state and will remain in that position until the power supply voltage is removed. The amount of time for the delay period can be adjusted using an external potentiometer.

The E7022BC004 can also be used with other external components, such as a switch or timer, that can be used to control the start and stop times of the delay period. The relay can also be used in a latching configuration, where it will remain in the ON position until the power supply voltage is removed, regardless of the position of the external switch.

In addition to the delay timer, the E7022BC004 also includes LED indicators for indicating the status of the relay, such as ON or OFF, as well as a voltage regulator for controlling the voltage supplied to the relay and preventing it from operating outside its rating.

Conclusion

The E7022BC004 is a versatile time delay relay from UTC, which can be used in a wide range of applications. It’s typically used to implement time delay functions in control systems, allowing it to increase system flexibility, reduce complexity and save space. It can also be used with other external components, such as switches and timers, to control the start and stop times of the delay period.
