ACV31112 Relays

Automotive relays perform a variety of functions in automotive systems, including starting, turning on lights, and controlling the power supply to multiple circuits. ACV31112 relays are among the most popular automotive relays used in vehicle applications.

The ACV31112 is a power relay with a maximum switching capacity of 6 amperes. It has two sets of seven pins, with three pole connections and four circuit connections. These connections are labeled P1, P2, P3, C1, C2, C3, and C4. The two sets of pins allow the relay to be connected to both a positive voltage and a negative voltage.

The ACV31112 has a two-position variant with an upper and lower position. In the upper position, the relay is off and in the lower position, the relay is on. This relay also has a selectable lockout feature so that once the desired position is set, the contacts are prevented from being changed.

The ACV31112 relay is typically used to control and regulate the power supply in automotive circuits, preventing unnecessary or excessive electrical current from flowing through the circuit. This prevents overloading or damaging of the circuit\'s components, and increases the safety and efficacy of vehicle systems. It is most often used to control the level of electrical current in systems that utilize high current carry capacity. Examples of common ACV31112 applications include starter circuits, alternator circuits, fuel injector circuits, and turn signal circuits.

In addition to its use in automotive circuits, the ACV31112 can also be used in other industries, such as marine and industrial applications. The ACV31112 relay is also widely used in motorsports, as it provides reliable protection against unstable power supplies. The ACV31112 relay can also provide overload protection in other, non-automotive applications, such as household appliances and other electrical devices.

The working principle of an ACV31112 relay is simple. The pins on the relay are connected to an electrically-powered internal electromagnet. When a current is sent through the electromagnet, it produces a magnetic field, which then attracts the armature and the contacts, closing the circuit. When the current is reversed or no current is supplied, the armature is released and the contacts open, which breaks the circuit.

The ACV31112 relay is a reliable and durable relay option for a variety of automotive applications. Its two-position variants and selectable lockout feature make it a popular choice for automotive system use. Its ability to protect against overloading is also valuable in prolonging the working lifespan of component parts.
