Time Delay Relays

Time Delay relays are a special type of electrical relay coils with an extra set of contacts. The extra set of contacts is connected into the electrical circuit in order to delay the action of the main contacts. The delay is achieved by connecting a coil across the main contacts, which acts as a resistor. The resistance value of the coil determines the amount of time it takes for the relay to activate.

H3M-AC200/220/240-D Application Field and Working Principle

The H3M-AC200/220/240-D is an economic and reliable time delay relay for all types of industrial control systems. It can be used to control motors, switches, lights, and other electrical components. It has a wide range of applications including industrial machinery, home appliances, office equipment, and more. The device is designed to provide a continuous and accurate time delay, with a response time of 0.1 second or less. The H3M-AC200/220/240-D features two main functions: a timer and a reset. The timer function allows users to set the time for an on/off cycle, while the reset feature enables users to reset the timer to its default setting. It also offers adjustable time delay settings with a range of from 0.05 second to 99.95 seconds, and a range of operating voltages from 24 to 250 volts AC.

The H3M-AC200/220/240-D works by detecting changes in voltage or current in the circuit. Once the voltage or current drops below a certain level, a timer begins. Depending on the timer setting, the delay time begins. If the voltage or current has not returned when the delay time is complete, the contacts open and the circuit is interrupted. If the voltage or current returns, the contacts close and the circuit is restored. This allows the user to control devices based on how long the voltage or current has been absent.

The H3M-AC200/220/240-D is a highly reliable device that provides a consistent performance for a variety of uses. Its adjustable time delay settings, adjustable voltage/current levels, and wide range of operating voltages make it ideal for a variety of applications. It is also easy to install and use, making it suitable for both professional and novice users. With its superior performance and reasonable price, the H3M-AC200/220/240-D is an excellent choice for any time delay relay needs.
