LEDs (Light Emitting Diodes) have been used for years to indicate the status of a device or system. LEDs are often used in combination with discrete outputs, such as the QLMP-P147-QR011, to indicate the type of state that a device or system is in. This article will discuss the application of the QLMP-P147-QR011 with respect to LED indication and its working principle.

The QLMP-P147-QR011 is a discrete device that offers an excellent combination of consistent output current and a rugged case design, making it suitable for many different applications. The device features a standard 2‑pole female header and a 2‑pole male header and can be used with both F‑type and S‑type fuses. It also has a built‑in fuse protection, allowing it to operate in environments where line faults or overvoltages may be present. With its level of sophistication and durability, it is ideally suited for use in numerous applications such as industrial, electrical, and fire safety systems.

When it comes to LED indication, the QLMP-P147-QR011 is primarily used to provide an indication of an open or closed state. Its 2‑pole male header allows the connection of up to three LEDs, which can then be used to visually signal whether the device is in the open or closed state. When the 2‑pole male header is open, the LEDs are illuminated, and when the 2‑pole male header is closed, the LEDs are off. If the open or closed state of the device needs to be determined, a low-pressure contact switch or an opto-isolator can be used to sense the open or closed state.

The actual working principle of the QLMP-P147-QR011 is quite simple. The 2‑pole male header of the device creates a low resistance circuit when it is closed. This low resistance circuit causes a current to flow through the LEDs, thus illuminating them. When the 2‑pole male header of the device is open, the LEDs are turned off because there is no current flow in the circuit.

The QLMP-P147-QR011 can be used for LED indication in a variety of applications, such as industrial machinery, fire safety systems, electrical control panels, and warning systems. Its rugged design and simple working principle make it suitable for a wide range of applications. The device is also a cost-effective solution that can provide reliable LED indication.

In conclusion, the QLMP-P147-QR011 is a discrete device that can be used for LED indication. Its 2‑pole male header allows connection of up to three LEDs, which can then be used to visually signal whether the device is in the open or closed state. Its rugged design and simple working principle make it a suitable solution for a variety of applications, such as industrial, electrical, and fire safety systems.
