Alarms, buzzers, and sirens are warning signals used to indicate potential danger or other important information. EFB-RL20C102 is one of these devices. Its application field and working principle will be discussed in this article.

Application Field

The EFB-RL20C102 is an audible alarm used in industrial, commercial, and residential applications. It is suitable for a variety of applications including fire, safety, security, or emergency notifications. This device can be used in warning systems, alerting lights for emergencies, and doorbells. It can also be used to indicate equipment failures or operational issues. It is particularly useful in environments where noise levels are high so that audible sound can be heard more easily.

Characteristics

The EFB-RL20C102 is a non-polar safetyRelay with a nominal operating voltage of 24 VDC. It is rated for continuous operation at up to 1A at 24VDC. It has a nominal supply voltage of 24VDC. The relay has an audible sound output of 100dB(A) at a distance of 1m and a frequency range of 0 to 5 kHz. It is also designed to be dust and moisture resistant.

Working Principle

The EFB-RL20C102 works by activating an electric circuit when the voltage increases or decreases. When the voltage exceeds or falls below the specified threshold, the relay can be energized or de-energized. This can create an audible alarm sound. This type of relay is equipped with a safety circuit capable of detecting a potential overheating in the motor and cutting off the power supply. Additionally, it is also capable of monitoring external voltage sources and detecting open or short circuits to ensure reliable operation.

Conclusion

In summary, the EFB-RL20C102 is a non-polar safetyRelay designed for industrial, commercial, and residential applications. It is equipped with a safety circuit capable of detecting potential overheating in the motor and can be used to create an audible alarm sound. Additionally, it has a nominal operating voltage of 24 VDC, a rated power of up to 1A at 24VDC, and a sound output of 100dB(A) at a distance of 1m. These characteristics make the EFB-RL20C102 an ideal choice for warning systems, fire and safety systems, and other applications requiring an audible signal.
