Time Delay Relays are versatile and often used in the industrial world where they are used to delay the changeover of a circuit for delay on break or delay on make applications. The most commonly used type of delay relay is the 7022BK. This type of relay is a time delay relay that is used in applications such as elevators, HVAC/R, and security systems.
The 7022BK is a time delay relay controlling two circuits - a control circuit and a controlled circuit. The device is designed with a pair of independent contact blocks, and each contact block has a single-pole double-throw switch. The control circuit operates at voltages up to 250 Vac or 125 Vdc. The controlled circuit can be used to control devices with a control voltage up to 240 Vac or 125 Vdc.
The device contains a timing unit, a time setting unit, and a time delay relay block. The timing unit consists of a capacitor connected in series with a resistor and a diode. The time setting unit contains a potentiometer connected in series with a resistor. The time delay relay block has a pair of normally open and normally closed contacts. When power is applied to the time delay relay block, the normally open contact is energized and the normally closed contact is de-energized.
When a signal is received by the control circuit, the timed duration of the device is activated. The time setting unit is adjusted to select the timing value, which is the amount of time before the device switches. The start time of the time delay relay is either manual or automatic, with either a delay on break or a delay on make application. When the triggered signal is removed, the time delay relay will reset and switch back to the original state.
The main purpose of the 7022BK is to control devices or processes by setting a time delay between the activation and reset of a control signal. This allows for automation of devices or processes, reduces the need for manual operation, and increases safety by removing the need for personnel to be in close proximity to a process.
Time Delay Relays like the 7022BK are used in various applications, ranging from industrial automation, to power control, and even in home security systems. In industrial applications, they can be used to control the operation of motors, pumps, and similar types of equipment. They can also be used to control the time necessary for processing operations, such as in conveyor systems. In home security systems, they can be used to trigger alarms after the expiration of a certain delay. Another common use of time delay relays is for time delay on make or break applications in HVAC/R systems.
Time Delay Relays offer a great degree of flexibility and control for various applications and devices due to their versatility and easy adjustability. The 7022BK is one of the more commonly used time delay relays due its wide range of application and easy adjustability. This type of time delay relay provides reliable, accurate control of process time and is essential in applications ranging from industrial to consumer electronics.
