Power relays refer to electrical switches operated by voltage. BR231D-450B3-28V is one of the power relays with voltage reach up to 28V, and holding current of over 2 Amps. It usually integrates a semiconductor which is controlled by small amount of voltage and current, and is then connected to electromagnetic mechanism.

The application field of BR231D-450B3-28V mainly includes two parts: Control Circuit and Power Circuit. In the control circuit, it is used to open and close the power switch, and eventually providing DC power to other electrical equipment. In power circuit, it is usually used as the input of PLC controlling system(Programmable Logic Controller) or control electric motor with voltage up to 28V and current of over 2 Amps.

The working principle of BR231D-450B3-28V belongs to Electromagnetic Relay\'s category. It contains Coil, Moving Core, Contacts, Armature and Spring. Coil is an electromagnetic coil which generates magnetic field when electricity passes through, and the magnetic field makes the moving core moves in and out of the Coil through Magnetic Attraction, then Armature acts as a switch to turn on and off the Contacts, which eventually open and close electric circuits. Spring is used to make sure the moving core returns to its original position when the electrical current is shut off. This process usually happens in a very short time, which makes it able for BR231D-450B3-28V to be used in situations such as PLC controlling systems.

BR231D-450B3-28V applies Advanced Automation Technology (AAT) to make sure the working accuracy would not be affected by external environment like humidity, temperature, dust and etc. The product is also equipped with breaking capacity protection and over temperature protection, which significantly enhances its reliability. Therefore, it\'s a valid choice in power relays field for current ≥2 Amps and voltage ≤28V.
