Power Relays, Over 2 AmpsRelays are electrical components that allow an external current to control an internal current. This is done by having an external current turn an internal switch on or off. Power Relays can control a much greater power than a typical switch, and JQ1A-24V is one of many relays on the market capable of doing this. The JQ1A-24V relay has many applications, and an understanding of its working principle can help to identify its limitations and capabilities.In the most basic sense, the JQ1A-24V relay has two states: an On state when it is in an external current, and an Off state when there is no external current. When the relay is in an Off state, no current is drawn from the external power source, and the internal switch is in an "open" position, meaning that the current is disconnected from the internal load. When the relay is in an On state, the current flows through the external power source and into the internal switch, which closes, allowing current to flow into the internal load.The JQ1A-24V relay is typically used for controlling high-current loads, such as those in automobile and HVAC (heating, ventilation and air-conditioning) systems. The relay is typically used to control loads in the range of up to 2.5 amperes, and the external current required for switching is in the range of 5V to 24V. In the case of applications which require more power than the JQ1A-24V relay can provide, a higher amperage relay is available.It should be noted that the JQ1A-24V relay is not recommended for use in applications that involve large current and voltage loads, as the internal switch can be damaged if it is used to carry more than its rated current and voltage. Additionally, the internal switch may need to be replaced if the external power supply is interrupted while the relay is in an On state, as this can damage the internal switch and reduce the life of the relay substantially.The JQ1A-24V relay is generally well suited for automotive and HVAC applications. Its internal switch can handle up to 2.5 amps, and the external power supply required for switching is in the 5V to 24V range. The life expectancy of the relay is quite good, although care should be taken to ensure that the external power supply is not interrupted while the relay is in an On state. Additionally, the total current and voltage carried by the relay should not be allowed to exceed its rated levels, as this could damage the internal switch and reduce the life of the relay.
