LEDs are a type of diode used to visually indicate presence of power, or alert the user to a specific condition such as a fault or the operating state of a system. This is the case with the WP7104PBC/Z, a discrete LED indicator. This article will discuss the application field and working principle of this type of LED.

The WP7104PBC/Z is a basic continuous two-level LED indicator that provides visual indication of power and/or system state. It consists of two columns of six LEDs, arranged in two separate circuits. When power is connected, the two circuits light up in different colors—red for the left circuit, and blue for the right circuit. When operating normally, the left circular LEDs stay lit, while the right circular LEDs blink in sequence. This type of LED is used for various purposes, including for indicating an alarm condition, providing visual feedback to the user during power logon operations, and checking for electrical continuity.

The working principle of a WP7104PBC/Z is quite simple. When power is supplied to the terminal pins, current flows through both the left and right circular LED circuits, lighting them up accordingly. When the system is in normal operation, the left row of LEDs stay lit while the right row of LEDs blink in a sequence, creating a visual indication of electrical continuity and system state. When an alarm or other fault condition is detected, the right row of LEDs will light up in sequence to warn the user of the problematic system state.

The WP7104PBC/Z can be used in a wide array of applications, from industrial and commercial settings, to residential and personal use. In industrial and commercial settings, the device is typically used to give visual indication of a system’s state, such as during power logon operations. The two-level and blinking LEDs can also provide visual feedback for various operations, such as closing and opening a door, activating a system, and security monitoring, etc. In residential and personal use, the device may be used as a status indicator for multiple devices connected to the same control system.

In summary, the WP7104PBC/Z is a discrete LED indicator, providing two-level lighting and blinking operation to indicate the state of power and system operation. Its application field is varied, ranging from industrial and commercial settings, to residential and personal use. The device is easy to use, and can be integrated into existing systems to provide visual feedback and status indication.
