Time Delay Relays are basically electrical relays with a built-in timer that can be adjusted to delay the energizing of the electrical load for a specified period of time. The PMH-10H-AC120V Time Delay Relay, is a popular product that has a wide range of applications in many industries.

Application field

The PMH-10H-AC120V Time Delay Relay can be used in various fields like automotive, industrial control, hvac, energy management and process control applications. It is specially designed for industrial control circuits where contactor control, motor or lighting control are required. This relay can also be used in applications such as motor speed control, temperature control, pressure control, surge protection and time delay control.

Working Principle

The PMH-10H-AC120V relay is a pot-type time delay relay that is actuated by pressing a special button. When the button is pressed, the relay’s timer is activated and the load connected to the relay is energized after a pre-set time delay. The button is normally a plastic former inside a stainless steel case that can be easily pressed.

When the timer is activated, a certain amount of energy is stored inside the relay and is released when the preset time has elapsed. The energy is released through a special contact that connects the positive and negative terminals of the relay. The contact closes after the preset time and the load connected to the relay is energized.

The PMH-10H-AC120V relay is equipped with two time ranges, which can be selected by an internal switch. The two time ranges are adjustable from 0.1sec to 10min and 1min to 10h. It has a compact size and is UL rated, which makes it suitable for use in industrial control and other electrical applications.

The PMH-10H-AC120V Time Delay Relay is an efficient and reliable device used for many applications. It is easy to install and operate and provides reliable protection against overload and equipment damage. It provides a variety of time delays, which can be adjusted to meet the needs of different applications.
