Time Delay Relays are among the most common types of relays, which are used to control both electrical and electronic circuits. The relays are actuated by a certain type of electrical signal and generally operate over a range of input voltages. When the incoming signal is strong enough to enable the relay to operate, the Time Delay Relay switches from its normally closed state to an open state and then back to its normally closed state once the relay has elapsed its predetermined time delay.

The 7022X3BT is a commonly used type of Time Delay Relay designed to provide repeatable and reliable on-delay timing operation, controlling both electrical and electronic circuits with a single electronically controlled adjustable time relay. The device can be used to control a wide variety of functions, such as controlling electronic circuits, sensors and switches, and controlling high-voltage electrical circuits.

The Time Delay Relay can be triggered by an analog signal, such as voltage, current, temperature, pressure and distance. The signal is transmitted from the source and determines when and why the switch closes or opens. The time delay of the relay can be adjusted, so that the duration from the start of the signal to the change of state of the switch can be adjusted to suit the application. This adjustment can be carried out manually or with digital programming.

When the 7022X3BT is used, the source signal has to reach a certain threshold for the device to detect and initiate the on-delay timing, so the source signal may be either digital or analog. The adjustable time delay determines when the switch opens and closes after the device has detected the threshold signal. When the device is triggered, it signals the on-delay time interval and then initiates the operation of the switch, either opening or closing, depending on the chosen setting.

The 7022X3BT is found in a broad range of applications, such as industrial process control, machine automation, medical instrumentation, automotive, heating and ventilation control, and even robotics. It is also used for items like circuit breaker trip and hold functions, lighting control, alarm systems, and many other industrial applications. The on-delay timing of the relay can also be used to control motors, tanks, and pumps in varying industrial environments.

The 7022X3BT Time Delay Relay consists of two different circuit boards, one which performs the on-delay timing and another which contains the electrical circuits and other necessary components. A power supply is required to supply the device with energy, while the output signals are sent through I/O connectors. The on-delay timing circuit is the most important element in the Time Delay Relay, which consists of an oscillator, a variable timer, a flip flop and a digital input counter. The oscillator produces a clock signal that is continuously monitored by the variable timer, which in turn calculates the elapsed time from the initiation of the source signal to the change of state of the switch. The flip flop continuously monitors the output of the variable timer and in the case of the 7022X3BT, the flip flop is used to control the digital input counter.

In summary, the 7022X3BT Time Delay Relay is used to control both electrical and electronic circuits over a wide range of input voltages. The adjustable time delay of the device can be used to control functions such as circuit breaker trip and hold functions and is found in a wide variety of industrial and commercial applications. The device consists of two separate circuit boards, one which controls the on-delay timing and the other, the electrical components. The adjustable time delay is governed by an oscillator, a variable timer, a flip flop and a digital input counter which monitors the output of the variable timer and changes the state of the switch accordingly.
