HC4D-DC100V-D

Power Relays, Over 2 Amps: HC4D-DC100V-D Application Field and Working Principle

The HC4D-DC100V-D is a power relay over 2 Amps with an application field for DC, DC motor and AC motors in the range from 0.46A to 2.2A. It supports a wide array of applications without needing assembly and safe and reliable operation is achieved through proven long-term vibration endurance.

This is a DC power relay with two main applications: DC motors and AC motors. It comes with 100V with a rated load current of 2.2A. It operates between a temperature range from -40°C to +125°C, or from -40°F to +257°F, featuring long-term vibration endurance and wide voltage range stability. The relay is DIN-rail mountable and its contactless design ensures the contact position of the power relay is not affected by external vibrations.

Working Principle

The HC4D-DC100V-D power relay works through the electromagnetic field effect, meaning it only needs to connect the power current and requires no other form of control. When the operating voltage exceeds a certain value, an electromagnetic field is generated that causes a pull on the armature. This action causes the contacts of the relay to close, which powers the circuit. In reverse, when the voltage drops, the armature is released as the energy in the electromagnetic field dissipates and the active contacts open. Automatic opening and closing of the contacts is achieved, and when the contacts are closed, the power for the motor is powered.

In terms of durability, the HC4D-DC100V-D is shock and vibration resistant, making it perfect for use in industrial environments where the movement of equipment and machines is often repetitive and powerful. It is also dust and water resistant with a IP40 and IP53 rating for dust and water resistance respectively. This makes it an ideal choice for machinery used in harsh or outdoor environments.

Advantages

The HC4D-DC100V-D power relay has a number of advantages compared to other power relays. Its contactless design ensures that its use is not affected by external vibrations, making it perfect for use in machinery and vehicles that experience a lot of movement. It also has a wide voltage range, meaning it can power various applications without needing extra components, such as transformers. The automatic opening and closing of contacts makes its use very easy, and its durability ensures that it does not require frequent repair or replacement.

Applications

The HC4D-DC100V-D power relay is mainly used for the operation of DC and AC motors, such as in refrigerators, pumps and other small machinery. Its contactless design also makes it suitable for use in motorised vehicles, such as tractors, forklifts and excavators, where its durability and resistance to shock and vibration makes it a reliable choice. It can also be used in machines for food and beverages, medical and pharmaceutical equipment, and instrumentation.

The HC4D-DC100V-D power relay is an ideal choice for use in motorised applications, particularly for those working in harsh or outdoor environments. It is shock and vibration resistant, dust and water resistant, and does not require extra components like transformers to operate. Its simple operation and reliable performance makes it perfect for a wide range of applications.
