LED Indication - Discrete

LED (Light Emitting Diode) technology has been increasingly utilized over traditional electrical or mechanical forms of indicating status. Discrete indicators are used to indicate the state or position of something, and the WP1503EC is one such product. The WP1503EC is an LED indicating device designed with a wide application field, notably being battery-based, low voltage and low power applications.

Applications

The WP1503EC is a great selection for Industrial Controls and Instrumentation applications. The device can be implemented in a variety of positions to indicate the status of low voltage devices such as motors, pumps, and valves. It is well-suited for use in these applications due to its flexible status indication design including Power On/Off, Start/Stop, and Open/Close indication. It is also suitable for portable equipment and communication devices, thanks to its compact size and large number of options.The WP1503EC is also used in various automotive applications. It has been used in car radio systems, Airbag sensors, and fuel injection systems for monitoring basic functionality. The device can also be found in automotive lighting systems in either rear/front or interior lamps. It is also popular in industrial lighting systems as its low voltage design is well-suited to this type of application.

Types

The WP1503EC is available in two different configurations:• Bi-Color Indicator: This is a two-tone indicator, in either red/green or amber/green, which is used to indicate two different states.• Multi-Color Indicator: This type of indicator is used to indicate up to four different states. This configuration is typically used for more complex applications such as indicating the position of multiple motors.

Features

The WP1503EC is an advanced LED indication device due to its wide range of features. These include combining illumination with a physical design to produce a reliable, cost-effective indication solution. It is also designed with a flexible range of lenses and mounting options, including surface mount and panel mount version, allowing you to customize according to the application.The WP1503EC also offers advanced features such as low drop-out LED drivers and an integrated microcontroller. This enables the device to have a high-level of diagnostic capabilities and the ability to switching between multiple configurations. This also allows the device to meet a wide range of environmental requirements such as operating temperature and vibration.

Working Principle

The WP1503EC is designed with a series of indicator LEDs that are arranged and connected in such a way that allows them to be controlled independently. Depending on the design of the device, when the input signal is applied, the integrated microcontroller activates the LED drivers which are responsible for powering the LED’s. The LED illumination is then brought up to the required brightness level.The device also allows for an input signal of either single-ended or differential-ended. For single-ended configurations, the device will provide an output of constant current, thus providing uniform brightness regardless of the current input signal. In differential-ended configurations, the device can respond to a changing input signal, enabling the device to be used for more complex applications such as position or speed indication.Another key feature of the WP1503EC is its ability to distinguish between high and low levels of input. This allows the device to be used for monitoring state change, allowing it to be used in more advanced applications such as programming a logic controller.

Conclusion

The WP1503EC is an advanced device designed with a range of features enabling it to be useful in a variety of scenarios. Its wide application range, lightweight and compact design, advanced features, and its ability to distinguish between high and low levels of input make it an ideal choice for low voltage applications. With its two configurations and its flexibility to respond to digital or analog signals, the WP1503EC is a great choice for a variety of displays.
