50739180974600F panel indicators, pilot lights, are used for many different types of monitoring and control applications. They normally provide a visual indication of an open, close or other condition. The device can be used to alert the user to a specified event. The most basic type of panel indicators, pilot lights are analog lights that show an indication of a state or condition. Below is a discussion of the common types of panel indicators, pilot lights and how they work.
LED Panel Indicators
LED panel indicators, often referred to as LED pilot lights, are some of the most versatile and inexpensive panel indicators available today. They are used in applications ranging from HVAC to industrial equipment and conveyor controls. There are several types of LED panel indicators including single and dual color models, momentary or latching switches, and diffused or rugged lenses. An LED panel indicator is driven by a transistor to provide a variety of functions, such as display a given state, indicate a status change, or indicate an input condition.
Incandescent Pilot Lights
Incandescent pilot lights, or lamps, were the traditional panel indicators used before the advent of solid-state technology. They are still used in some applications, especially those requiring dim illumination. The lamps are typically powered by 24V AC or DC and can be configured for a single or dual-color indication. Two 6V lamps can be used and wired in series, while one 12V lamp can be used for a single indication. The lamps must be wired in series to prevent blown bulbs.
Neon Pilot Lights
Neon pilot lights are an inexpensive alternative to incandescent lamps. They are typically powered by 120V AC or DC and offer a brighter illumination than incandescent lamps. There are two types of neon pilot lights: single-colored and dual-colored. Single-colored neon pilot lights glow brightly when they are energized and do not require an anode connection to light. Dual-colored neon pilot lights use two circuits, one for each color, and require an anode connection to light each color.
Bi-Color Panel Indicators
Single or dual-color bi-color panel indicators use two LEDs, one red and one green, to display two distinct colors. This allows the device to be used in applications that require a green or red indication to show either the "on" or "off" status. The color of the light is determined by the polarity of the applied voltage. The device is powered by 12V DC and requires an external power source.Buzzers and Sounders
Buzzers and sounders are useful for panel indicators that require an audible indication. They are typically powered by 24V AC/DC and can be either pulsed or continuous. The devices can also be configured for a single or dual audible indication. For example, a single indication may be used to indicate a warning event, while a dual indication may be used to indicate an alarm or fault condition.Working Principle
The basic operation of panel indicators is to provide a visible indication of a state or condition. The device is typically powered by a 12V DC or 24V AC/DC power source and connects to a signal source such as a circuit control board. The signal source is typically a contact closure or signal voltage such as 0/4-20 mA. When the signal source is activated the panel indication will be triggered, providing visual or audible indication of a given state or condition.The specific data is subject to PDF, and the above content is for reference
