PCN-112D3MH is a type of power relay, with 2 Amps or more rating. It is widely used in various control and switching applications, due to its stable performance and simple structure.

The PCN-112D3MH is a galvanic-isolated D-contact relay, which is manufactured from high quality plastic and epoxy potting material for strong insulation and superior performance. The relay is composed of a coil, an armature and a normally closed contact, and has a resistive load capacity of 40W. It is equipped with an integrated diode protection circuit, which helps protect the relay against high voltage transients, also providing superior EMC-protection against external noise.

The working principle of the PCN-112D3MH power relay is simple. When the rated coil voltage is applied, the coil will be energized and create a magnetic field surrounding the armature and the normally closed contact. This magnetic field will make the armature and the contact move apart, breaking the circuit and allowing the relay to turn on. When the voltage is removed from the coil, the magnetic field will cease and the armature and the contact will be allowed to move back together, completing the circuit and turning the relay off. This simple action enables the relay to be used for controlling power in various applications – for example, to turn on a motor, an electric heating element, or to switch a power supply off or on.

The PCN-112D3MH power relay is used in a variety of control and switching applications, including industrial control systems, telecom networks, process automation, and residential and commercial environments. It is highly reliable and can be used in all kinds of harsh environments, such as high or low temperature, high humidity, high vibration and high electromagnetic interference. In addition, the relay has a long life expectancy due to its integrated protection circuits, and also features low power consumption and high electrical noise immunity.

In conclusion, the PCN-112D3MH power relay is a highly reliable product with excellent performance, and is suitable for a vast range of control and switching applications. It is easy to use and maintain, and can be used in many different kinds of environments. The simple working principle and integrated protection circuits make it an ideal choice for various control and switching applications.
