Power relays are widely used in various application fields due to their low cost, light weight, dependability, reliability, and good power dissipation. The 7940034328 power relay is one such relay, and it has a maximum power rating of 2 Amps. In this article, we shall discuss the application field and working principles of the power relay 7940034328.

The 7940034328 power relay is mainly used in switching applications, in order to control the flow of current between two circuits. This relay is capable of switching both AC and DC currents, with a maximum load current of 2 Amps. It has a high switching capacity and can handle loads such as motors, pumps, and resistive loads. It is also used for controlling the amount of power being supplied to various devices.

The 7940034328 power relay has two types of contacts: normally open (NO) and normally closed (NC). The NO contact is the main contact that the user interacts with when operating the relay. It has the ability to switch the current on and off, depending on the user’s input. The NC contact is a secondary contact that is used in applications where a normally open switch is not necessary. The relay also has two electrical terminals, one for the input power and another for the output power.

The working principle of the 7940034328 power relay is based on the electromagnetic attraction and repulsion between the relay’s moving contacts. When the switch is in the open position, the electromagnetic attraction causes the movable contacts to close. On the other hand, when the switch is in the closed position, repulsion forces the contacts open. This process is repeated when the switch is in either position.

In order to control the current flow through the relay, the user can manipulate the input signal. This can be done by applying a voltage source to one of the input terminals, which causes the magnetic field to either attract or repel the movable contact, depending on the voltage applied. The voltage supplied to the input terminal will determine the force exerted on the movable contact, and the amount of current allowed through the relay.

The power relay 7940034328 is widely used in a variety of applications such as home appliances, industrial equipment, automotive and communications devices. It offers a cost-effective switching solution that is reliable and robust. It is also economical in terms of its power consumption, making it a viable choice for applications where power is a critical consideration.

In conclusion, the 7940034328 power relay is a versatile device that is suitable for switching AC and DC currents, up to a maximum load current of 2 Amps. It is capable of controlling the flow of current through a relay, by manipulating the input signal. It is used in various applications such as home appliances, industrial equipment, automotive and communications devices, and offers a dependable and cost-effective switching solution. It is also economical in terms of its power consumption, making it a great choice for applications where power is an issue.
