PM4S-A2C60M-AC120V

Time Delay Relays (TDRs) are electrical components that provide an automatic way to control or delay the operation of a circuit, for a predetermined amount of time. The PM4S-A2C60M-AC120V time-delay relays are commonly found in many industrial, commercial and domestic applications. This article will discuss the features and working principles of this type of relay and the application fields where it is commonly used.

Features of PM4S-A2C60M-AC120V Time Delay Relays

The PM4S-A2C60M-AC120V is a time delay relay designed for use with alternating current power supply systems. It is a two-pole relay and is rated for 30A at 120VAC. The time delay range is adjustable from 0.1 seconds to 60 minutes with a single-stage manual reset. It is equipped with an LED indicator to alert the user when the time delay is satisfied. It is also equipped with a red reset button for manual reset and an adjustable knob for setting the delay time. The unit is mounted on a 9-inch base and features screw-type terminals for wiring in different circuits.

Working Principle of PM4S-A2C60M-AC120V Time Delay Relays

The PM4S-A2C60M-AC120V time delay relay is designed to work with alternating current. When power is applied to the relay, a timer circuit is initiated. This timer circuit either starts counting up or down depending on the setting of the adjustable knob. When the amount of time set on the knob has passed, an internal switch closes, and the relay will remain in this state as long as power remains applied. When power is removed, the internal switch will open, resetting the time delay.

Application fields and uses of PM4S-A2C60M-AC120V Time Delay Relays

Time delay relays such as the PM4S-A2C60M-AC120V are commonly used in a wide variety of applications. Some typical applications are:

• System startup and shutdown control
• Timer functions for automatic lighting systems
• Release of doors in large enterprises
• Motor maintenance assistance
• Level control timer in water tanks

These relays are also used to control ON/OFF cycles in combustion furnaces, pumps, and central heating systems. They are also used to control exterior alarms, interior lighting, and other automated systems. Time delay relays are ideal for controlling long wait and start up times. They are also used in conjunction with other components in automated systems.

Conclusion

The PM4S-A2C60M-AC120V is a reliable time delay relay used in many industrial, commercial, and domestic applications. It Offers adjustable time delay range and wide application fields. The main principle of the TDR is that it uses a timer circuit which enables an internal switch to close after a predetermined amount of time, thus allowing for delayed operation of a circuit. This makes time delay relays ideal for many automation and control applications.
