Power Relays, Over 2 Amps

The HJ2-DC110V is a type of relay with a maximum rated current of up to 2 amps. It is mainly used in automatic control systems and industrial machines, and is suitable for applications that require a frequent switch of the load power supply. This type of relay is also commonly used in alarm systems to detect and monitor the variation of the power supply voltage and to activate the alarm when the voltage exceeds set limits.

Application Field

The HJ2-DC110V power relay is primarily used in applications where an overload or short circuit should be prevented, including in automatic control systems and industrial machines. It is designed to provide reliable, low power switching, making it suitable for use in harsh industrial environments such as oil refineries, chemical plants, and manufacturing processes.

The HJ2-DC110V is also used in alarm systems which require reliable switching of the power supply, in order to detect specific conditions and activate the alarm. This type of relay can be used to detect when the power supply voltage is outside of a set limit, indicating that the system needs to be checked. This ensures that any faults in the power supply or equipment can be detected and rectified before any serious damage is caused.

Working Principle

The working principle of the HJ2-DC110V relay is based on an electromechanical contact. The relay has a normally open contact, which is held in the open position with a spring. When energized with DC voltage, the contact is then moved into the closed position, allowing electricity to flow. This process is reversible, and when de-energized, the contact is released, allowing it to open again.

The HJ2-DC110V relay also includes an internal circuit breaker that helps to protect against prolonged high current. This feature helps to prevent the relay from overheating and becoming damaged, and is particularly beneficial in applications where the load power supply is frequently switched on and off.

Conclusion

The HJ2-DC110V is an electromechanical power relay with a maximum current rating of up to 2 amps. This type of relay is commonly used in automatic control systems and industrial machines, where a reliable, low power switch is required. It can also be used in alarm systems to detect abnormal conditions and activate the alarm, ensuring that any faults in the power supply or equipment are rectified promptly. The internal circuit breaker helps to prevent the relay from overheating and becoming damaged, making it suitable for use in harsh industrial environments.
