Belonging to an extensive class of automotive relays, the ACJ5112P from TE Connectivity acts as a high-performance, versatile power relay capable of controlling high-current circuits. Featuring a robust design, high peak current capability, and several versatile outputs, this device is an ideal choice for a variety of automotive applications.

ACJ5112P Application Field

The ACJ5112P offers numerous features and configurations to effectively control high-current circuits in automotive systems. Because this device is able to handle current up to 2A, it can be used in many applications, such as alternator control, generator control, starter motor control, battery charging systems, and auxiliary battery control. It can also be used to secure the switch-off of power to the load when the controller is powered down. Moreover, due to its adjustable threshold, the ACJ5112P can be used with all sorts of loads. This relay is also well-suited for a number of non-automotive applications including current regulation, remote site switching, and more.

ACJ5112P Working Principle

The power relay features a robust design with 10A switching capability at 20rs and AC1 rating. It is also equipped with multiple outputs, eliminate the need for additional relays. The ACJ5112P provides two configurations – reversing and solid-state – and a wide variety of features, including over- and under-voltage protection, adjustable threshold, end-of-life signalling, and a ballast-position indicator.

The working principle of the ACJ5112P is based on two different outputs. The reversing output allows the relay to switch between the output and common pin of the DC circuit. The reversing output is used for alternator control and generator control or for switching between a primary and secondary power source. The solid-state output provides a direct connection between the load and the supply, allowing a DC voltage to be connected to the relay without any additional circuitry.

The ACJ5112P has a unique feature, an adjustable threshold that can be manually adjusted to facilitate the switching of devices at higher or lower voltages than the nominal 12V output. This adjustable threshold allows the ACJ5112P to be used in many different types of applications.

As with many electronic components, the ACJ5112P also includes end-of-life signalling. An LED or signal can be provided to indicate the end of life for the device. This feature helps prevent any unexpected failure in the system due to the relay going bad.

Therefore, the ACJ5112P offers a versatile and robust relay designed to control high-current circuits in automotive systems. Its various features and configurations make it suitable for a variety of applications in the automotive field. Its adjustable threshold, combined with its end-of-life signalling capability, provide optimum performance and reliability.
