PM5-KWD

Panel indicators are devices specifically designed to inform operators of current and past system operation. They are frequently found in industrial, process control and automation applications. The PM5-KWD is one type of panel indicator designed provide this service. It is a LED based device which is visible in most lighting conditions and incorporates several features.

The PM5-KWD works by making an electrical connection when a specific condition is detected. This connection has a direct effect on the illuminated status of the LED. When the LED is illuminated, the condition is indicated as “on”. When the LED is extinguished, the condition is indicated as “off”. The PM5-KWD utilizes this concept of illumination and extinction to create an effective, efficient and reliable way of monitoring a range of system conditions.

The LED is controlled through the use of two adjustable potentiometers connected to the LED supply voltage. A low setting will cause the LED to dimly illuminate while a high setting will cause the LED to be brightly illuminated. It is this adjustable nature of the PM5-KWD that makes it very versatile when used in different applications.

The working principle of the PM5-KWD is very simple. When a condition is detected, an electrical connection is made which causes the LED to illuminate at the current setting. An example of this would be in an industrial oven where a thermocouple is used to detect when the temperatures has reached a certain level. Once the temperature is detected, the LED will illuminate indicating that the oven has reached its desired temperature.

In addition to indicator lights, the PM5-KWD can also be used as pilot lights. Pilot lights provide an indication of system state through the use of colors. The PM5-KWD is capable of illuminating multiple colors to give a more detailed indication of what is happening within the system. For example, red may indicate an error condition while green may indicate everything is running smoothly.

The PM5-KWD can also be used to create audible alarms. This is done by wiring the PM5-KWD in series with a buzzer or horn. When the LED is illuminated, the buzzer or horn will sound indicating an alarm condition. This is especially useful in critical systems where a visual or audible alarm is necessary to alert personnel as to an unexpected system state.

The PM5-KWD is a versatile and reliable device which can be used in a range of applications. Its ability to be adjusted to indicate a multitude of conditions as well as its ability to provide both visual and audible alarms makes it an ideal device for many applications. It is specifically designed to give operators up to date information on system state in a variety of industrial, process control and automation applications.
