Time Delay Relays

Time delay relays are relays that are designed to delay the switching of electrical circuits for a pre-determined time. They are often used as a safety measure to provide a delay between the activation of a primary circuit and the activation of a secondary circuit. The 7012NK model is a time delay relay that is designed for a wide range of applications.

7012NK Application Field

The 7012NK time delay relay is ideal for various industrial applications such as motor starters, timer circuits, home appliance control circuits, infrared remotes, and HVAC/R systems. It has a built-in adjustable timer and selectable timing range, making it highly versatile. The 7012NK time delay relay also includes a pre-wired power source connector with screw terminals. This allows for easy installation and maintenance.For example, the 7012NK time delay relay can be used in HVAC/R systems to adjust thermostat settings. In this case, it would be used to switch on the cooling or heating systems once the room temperature reaches a certain level. This helps to ensure that the system runs efficiently and consumes less energy than if it were switched on constantly.The 7012NK time delay relay can also be used in remote control systems. It can be linked to an infrared receiver that activates the relay upon receiving a command from a remote. This makes it easier to operate home appliances such as television sets, air-conditioners, and lights without having to manually operate the appliance. The 7012NK time delay relay is also suitable for motor starter applications. The adjustable timer settings can be adjusted to allow for the motor to start at a predetermined time or in a certain amount of time. This helps to prevent overloads or sudden surges of electricity, as well as providing safety to the motor.

7012NK Working Principle

The 7012NK time delay relay works by delaying the switching of an electrical circuit. The relay is connected to both the primary circuit and the secondary circuit. When the primary circuit is activated, a signal is sent to the relay which then delays the switching of the secondary circuit. The timing or duration of the delay can be adjusted using the relay’s adjustable timer. This timer is controlled using a timer knob which can be turned to a specific setting to alter the timing of the delay. The 7012NK time delay relay can be set to as little as 0.5seconds up to 24 hours. The 7012NK time delay relay also includes a pre-wired power connector. This connector contains two terminals which are used to power the relay’s main circuitry. The power connector also includes an LED light that indicates when the power is on and when the relay is activated.

Conclusion

The 7012NK time delay relay is a versatile and dependable time delay relay that is suitable for a wide range of applications. It is capable of delaying the switching of electrical circuits for up to 24 hours and includes a pre-wired power connector for easy installation. It is capable of ensuring safety in motor starters and other systems.
