Time delay relays are electrical circuits designed to facilitate specific functions such as delay on, delay off, and trigger pulses. They have been used in a variety of industrial and automotive applications. PM4HF8-M-AC240VW is one such time delay relay, and it can be used in many different applications and has a variety of features that make it a great choice for industrial and automotive purposes.

PM4HF8-M-AC240VW application field

PM4HF8-M-AC240VW is a versatile time delay relay that can be used for a variety of purposes such as controlling water level in a tank, turn on lights after doors open, and reset time delays for devices and other applications that require a set time sequence. It can also be used for controlling motors, determining door locking time delay, regulation of hoisting and conveyor systems, etc. This product is designed to operate in a wide variety of military and industrial environments and is suitable for both AC and DC applications.

PM4HF8-M-AC240VW Working Principle

PM4HF8-M-AC240VW is a single-phase, single-action, two-stage time delay relay. It is designed with a single input voltage of 90 to 240VAC, which provides adjustable currents and is suitable for AC and DC applications. The time delay relay has two distinct stages that are a fixed stage and an adjustable stage. The fixed stage includes an inrush arrestor as well as overload protection, and can provide 0.5-5 second timing range. The adjustable stage is programmed via an onboard LCD and includes a 50 millisecond to 30 minute timing range.

The time delay relay also features an under voltage protection and a reset/interrupt function that allows you to reset the set time. The reset/interrupt function is used to reset the product and is available during setting or after the product is released. In addition, the time delay relay also features a power input indicator that is activated when power is supplied to the product.

Conclusion

PM4HF8-M-AC240VW is a versatile and reliable time delay relay that can be used for a variety of applications. It has adjustable currents with a wide voltage range, two stages of time delay, and provides protection in the event of an overload or voltage fluctuation. It is also highly effective in controlling motors, determining door locking time delay, and resetting time delays for various devices.
