Panel indicators are small light-emitting devices mounted on the surface of a device or piece of equipment and used to indicate its operational condition. Pilot lights are small light-emitting devices that are used to indicate the status of a control mechanism.

The PM5-A12R28V is a panel indicator and pilot light manufactured by Niebergeller Corporation. It is an LED-based unit that has a chromed or black plastic bezel and a round lens construction that provides a bright and vibrant indication of device status. The PM5-A12R28V has three distinct operating modes: steady on, flashing and sequential blinking. Its LED can be self-generated when wired snappily, providing steady on or sequential blinking indications. The indication light source can also be externally controlled, and offers flash or steady on depending on the polarity of the applied voltage.

The PM5-A12R28V is designed specifically for applications requiring precise indication of device or equipment status. It is commonly used in industrial automation and process control applications such as factory automation, automotive, aircraft, computer communications system, medical instrumentation, and marine systems. The PM5-A12R28V can be used to indicate the state of switch position, machine status, emergency or warning alarms, or simply to emphasize signals or information. It can also be used to direct workers or operators in crowded and confusing shops to locate specific stations or devices.

The working principle of the PM5-A12R28V is relatively straightforward. As previously mentioned, the device comes in three distinct operating modes: steady on, flashing and sequential blinking. With steady on, the LED remains lit permanently once the power is applied. With flashing, the LED will flash at a predetermined rate, and with sequential blinking, it will begin to blink in a sequence until the power is turned off.

The power that is used to power the indicators is the voltage applied by users. This voltage can vary according to the application and the type of power supply that is used. Typically, it ranges from 5 volts to 24 volts, but it can also be higher if needed. Once the desired voltage is applied, the indicator is ready to work as per the user’s needs and expectations.

In order to achieve the desired indication, the user needs to connect the indicator terminals to the voltage source or controller. Once power is applied, the device starts indicating as desired. The PM5-A12R28V can be adjusted for brightness and duration simply by modifying the duty cycle of the applied voltage. By changing the duty cycle of the power, the user can obtain the required indication levels and time duration for the indication.

The PM5-A12R28V is a versatile panel indicator and pilot light device that can provide precise indication of device status with ease. With its durable construction and simple operating principle, the PM5-A12R28V is well suited for a variety of industrial automation and process control applications. It comes in a variety of lens styles and colors, allowing users to customize the look and feel of their devices.
