Power relays are electro-mechanical tools that are often used to connect or control electrical circuits. The BR231-112A1-12V relay is a large power contactor that can be used for applications requiring higher amperage than the average power relay. In this article, we will discuss the application fields and working principle of the BR231-112A1-12V relay.

Application Field

The BR231-112A1-12V relay is an alternative to electromechanical contactors that can carry as much as 12 Amps of current in DC and can switch up to 240 Volts AC. This relay is primarily used in HVAC systems, automotive applications, and power mains supplying drive systems, lighting, or other large AC loads. Common applications include controlling high-power motor starters, water heaters, lights, and other AC loads, as well as controlling motor speeds and directions. The BR231-112A1-12V relay is also suitable for domestic applications, such as switching between AC and DC power sources.

Working Principle

The BR231-112A1-12V relay works by using an electromagnetically-actuated switch. When current passes through the electromagnet, it creates a magnetic field, which in turn moves the switch\'s armature, thus connecting or disconnecting the load. The armature is held in place by a spring, and the relay\'s design ensures that the contacts are securely made and broken when the armature moves. The power relay also has a small secondary coil, which further reduces the current in the circuit and helps prevent arcing when the contacts are broken.

The BR231-112A1-12V relay can also be used with a variety of auxiliary contacts. These are additional contacts that can be used to connect other circuits, allowing a single relay to control multiple devices. Auxiliary contacts are useful for controlling multiple AC loads simultaneously, and they can also be used for signal logic applications. These contacts are designed to be capable of carrying up to 1 Amp of current and are usually rated for 30 Volts AC.

The BR231-112A1-12V relay is a powerful and reliable tool for switching high current DC and AC loads. The robust design ensures reliable operation in a wide variety of applications, and its ability to accept auxiliary contacts adds versatility to any system. The BR231-112A1-12V relay is an excellent choice for any application requiring a robust and reliable contactor.
