Panel indicators, such as the M22N-BN-TWA-WA, are used to indicate when an action has been taken, or when a system is functioning normally. They use a simple yet efficient design to provide visual and audible feedback to the user. The M22N-BN-TWA-WA in particular uses two LEDs, LED1 and LED2. These LEDs are used to indicate two different status, either normal or failure. When both LEDs are illuminated, it indicates that the system is functioning normally and that no action has been taken. When only one LED is illuminated, it indicates that a malfunction has occurred, and the corresponding LED will be lit. This helps the user identify which LED indicates normal operation and which LED indicates failure.

The M22N-BN-TWA-WA employs a more sophisticated design than just the use of two LEDs. It is powered by 220V AC, and has three terminals on the bottom. Two of these terminals are used to control the two LEDs, while the third terminal is used to receive signals from the system controller. This signal tells the indicator when to turn on the LED, and when to turn it off. The terminals also feature a yellow LED which is used to indicate a fault condition.

When there is a fault condition, the LED will be illuminated, assuming that the switch is in the “ON” position. The user needs to then press the “TEST” button, which will indicate a successful operation once the fault has been corrected. The physical design of the M22N-BN-TWA-WA also features audible feedback, with a built-in buzzing sound that is activated when the TEST button is pressed.

The M22N-BN-TWA-WA is highly versatile, as it can be used in a variety of applications. These include but are not limited to industrial control panels, lighting controls, switch panels, and alarm systems. It can also be used for fire alarm systems, overload protection systems, and power supply protection systems. Its versatility also extends to the size of the unit; the M22N-BN-TWA-WA can be purchased in sizes ranging from 16mm to 48mm.

The working principle of the M22N-BN-TWA-WA is quite simple. The controller will send a signal to the indicator, which will either turn on or off the LED1 or LED2. This signal can also be used to activate the audible feature, which will buzz when the TEST button is pressed. When a fault is present, the yellow LED will be illuminated, and the TEST button need to be pressed in order to reset the indicator.

Overall, the M22N-BN-TWA-WA is a reliable and versatile panel indicator that can be used for a wide variety of applications. Its design features two LEDs, which can indicate normal and fault conditions. It is also capable of providing audible feedback when needed. It can be used in industrial control panels, lighting controls, switch panels, alarm systems, and other similar applications. The simple yet effective design ensures that it is easy to use and reliable for long-term operation.
