Time Delay Relays

Time delay relays are used to allow a circuit to remain on for a predetermined period of time, or to activate a circuit or process at a certain elapsed time. The H3Y-4 AC240 120S is one such time delay relay. This piece of equipment is designed to permit adjustable time delays from 0 to 10 sec.

Application Field

The H3Y-4 AC240 120S time delay relay can be used to replace traditional mechanical timers and is suitable for many applications. It can be used in home appliances, industrial equipment, and many other settings. It can be used to delay the opening or closing of a switch, and is perfect for controlling layoff time and load times. It can also be used in place of fixed time delay relays, such as in motor controllers for start-up, shut down, and timer-controlled lighting systems. Additionally, it can be used for various other time delay applications, such as in hoist control systems and conveyor systems.

Working Principle

The H3Y-4 AC240 120S is a common type of time delay relay. It utilizes an internal delay unit to adjust the delay time, which is then triggered by an external electrical switch connected to the input terminals. When the external switch is activated, a signal is sent to the delay unit, and the delay begins. When the delay unit times out, a signal is sent to the output terminals, which will activate the connected circuit. The H3Y-4 AC240 120S includes a dial for setting the length of the delay period. Adjustment of the dial changes the amount of time the output relay is activated, allowing the user to change the relay’s output within the range of 0 to 10 seconds. This is done by adjusting the dial, setting the 0 position as the maximum delay time and the 10 position as the minimum delay time. Once the time delay has been set, the input terminal’s switch remains activated unless the entire power to the device is cut off. In this case, the time delay will reset, and the switch must be reactivated before the cycle begins again. In summary, the H3Y-4 AC240 120S time delay relay is a versatile and reliable piece of equipment that can be used in many different applications. It is able to provide adjustable time delays from 0 to 10 seconds, and is ideal for a range of applications, including home appliances, industrial equipment, motor controllers, and lighting systems.
