Panel Indicators, Pilot Lights

The 2191QL1-6V are types of panel indicators, also known as pilot lights. They are used to indicate the nature of the process inside various machines and equipment. In industrial operations, it is important to be able to detect any irregularities that might cause malfunction or harm. Because of this, indicators are often fitted in machines to provide visual notification of any changes that may occur in the working situation.

2191QL1-6V panel indicators are available in a range of designs that can accommodate a variety of application needs. Typically, they are configured to work with a voltage range of either 12 or 24V DC. The device can accept voltages as low as 6V and as high as 33V at a maximum of 1A current.

The working principle behind these indicators is generally the same regardless of the configuration. A current passes through a coil, creating an electromagnetic field. This field attracts the armature housed in the indicator’s housing. When the armature is activated, the latch contact is opened or closed and an indication is given to the user. Indicators can use either an LED or an incandescent bulb in order to emit the indication. In addition, some indicators come with a buzzer or alarm in order to provide an audio indication of any changes in the working environment.

2191QL1-6V panel indicators are used in a variety of industries, including manufacturing, power generation, chemical processing, and telecommunications. In these industries, it is important to be able to detect changes in the environment quickly and effectively. The indicators help provide early warning of potential emergencies, allowing operators time to take the necessary steps to ensure safety.

The 2191QL1-6V panel indicators are available in a variety of colors, including green, red, orange, yellow, and blue. This allows the device to be used in a range of applications, from warning light and audio alarms to process monitoring. By having a variety of colors, operators can easily identify potential problems without having to refer to a detailed logbook.

In summary, the 2191QL1-6V panel indicators are primarily used for detecting changes in an industrial environment. They work by creating an electromagnetic field which causes the armature to be attracted and actuates a switch, giving an indication to the user. Available in a range of colors, the indicators can be used to give visual, audible, or both warning of potential problems. As such, they are an essential piece of equipment in industries such as manufacturing, power generation, chemical processing, and telecommunications.
