LED indications are common products in today\'s world, providing an effective way to convey information and visual cues to people. The 19-217/BHC-ZL1M2RY/3T is a type of LED indicator which is used primarily in the industrial and commercial contexts. This article will discuss the application field and the working principle of 19-217/BHC-ZL1M2RY/3T.

Overview

The 19-217/BHC-ZL1M2RY/3T is a single-sided viewing angle, two-color LED indicator. It offers two elements - a red LED and a green LED - which can be used together or independently. The red LED is used as an on/off indicator, while the green LED can be used to indicate a state change in the system. This type of indicator is commonly used in industrial and commercial contexts, such as in automation systems and machinery control.

Application Field

The 19-217/BHC-ZL1M2RY/3T is a popular choice for industrial and commercial applications. It is used in automation systems and machinery control due to its versatility and ease of use. The indicator can be used to indicate a variety of states, from on and off to alarm and standby. Additionally, the red and green LEDs can be used to indicate different states in a system, such as an error condition or machine fault.

The indicator is also often used in video surveillance systems. The green LED serves as an on/off indicator, while the red LED indicates whether or not the system is recording. This type of LED indicator is also commonly used in traffic management systems, with the green LED indicating the normal traffic flow, and the red LED indicating an abnormality, such as a congestion.

Working Principle

The 19-217/BHC-ZL1M2RY/3T LED indicator operates on an open-drain logic system, which means that the LED turns on when the voltage at the anode of the LED is greater than the voltage at the cathode. The LED is connected to a power supply and a digital signal processor (DSP). When a digital signal is sent from the DSP to the power supply, a current is sent to the anode of the LED, causing it to light up. The current is then sent back to the DSP, and the cycle repeats as long as the digital signal is still active.

The 19-217/BHC-ZL1M2RY/3T can be used in conjunction with a switching circuit to control the current flow to the LED in order to achieve the desired effect. The switching circuit can switch the current to the red LED or the green LED, depending on the desired effect. This allows the user to control which LED is illuminated and when they are illuminated.

Conclusion

The 19-217/BHC-ZL1M2RY/3T is a versatile two-color LED indicator that is commonly used in industrial and commercial applications. It operates on an open-drain logic system, with a switching circuit for controlling the current flow to the red and green LEDs. It is effective for indicating different states in a system, such as on and off, status change, error, and recording. This makes it a popular choice for industrial and commercial applications.
