Time Delay Relays are devices used to protect, start, stop, delay and power a variety of electrical and electronic components. They are also used to control the switching of electric signals or power circuits. QM4HS-D2C-48V is one type of time delay relay that is widely used in various applications.

What is a QM4HS-D2C-48V Time Delay Relay?

The QM4HS-D2C-48V time delay relay is an electromechanical timer that can be set for a various timing functions. It is commonly used to control the switching of motor-operated devices such as lathes, milling machines, injection molding machines, robotics, and other electrical and electronic components. This type of relay is also beneficial when used for applications where continuous or repetitive ON/OFF cycle control is required. It is highly reliable and can come in either a normally open (NO) or a normally closed (NC) version.

Applications of the QM4HS-D2C-48V Time Delay Relay

The QM4HS-D2C-48V time delay relay is used in many different applications. Some of these include motor control, surge protection, low voltage control, overload protection, and timer control. It can also be used in industrial, HVAC, and automotive applications, for power and lighting control systems. It can be used to control devices such as motor starters and solenoids, or to provide a delayed start when electric circuits are switched on or off.

Working Principle of the QM4HS-D2C-48V Time Delay Relay

The QM4HS-D2C-48V time delay relay is a timer that uses a voltage input to control an electrical output. When the voltage input is applied, it energizes the relay coil, which then closes the output contacts. When the set time interval is reached, the output contacts open and the output voltage is removed. The time delay can be set by changing the value of the preset resistor, which is usually located on the side of the unit.

The timer includes a circuit board, which is connected to the contacts. The PCB holds the appropriate circuitry for the delay setting, and the output and input terminals. The PCB is also the location of the power supply, which can either be an AC or DC voltage. When the timer is activated, the voltage is applied to the contacts, creating a pulse. This pulse is sent to the circuit board, setting the timer to the desired delay time.

The QM4HS-D2C-48V time delay relay also has a number of other features, such as adjustable timing, repeat cycling, and adjustable trip points. Adjustable timing allows for the duration of the delay to be set, while repeat cycling enables the unit to automatically reset itself after a predetermined period of time. Adjustable trip points allow for the maximum and minimum voltage values that must be maintained in order for the unit to work correctly.

The QM4HS-D2C-48V time delay relay is a highly reliable device that can be used in a variety of applications. It is especially useful when used to control motor-operated devices or power circuits, as it can provide a delayed start when electric circuits are switched on or off. Its adjustable timing, repeat cycling, and adjustable trip points make it a versatile and reliable device for a range of applications.
