2150QA1

Panel Indicators, Pilot Lights

2150QA1 is a panel indicator series designed for applications where accurate indication of process variable values or alarm conditions is required. 2150QA1 is suitable for a wide variety of process control instrumentation and machines. 2150QA1 is composed of a bright LED display which is visible even in brightly lit surroundings

The 2150QA1 panel indicator works by exposing a light-emitting diode (LED) to an alternating or direct current field, whose ability to conduct electric current and emit light varies according to the voltage or current it senses. The 2150QA1 is generally used to measure an input signal or a combination of signals from other devices or systems, such as transducers, strain gages, resistors, and thermocouples. The signal is processed by a circuit board, or other logic, to generate an output signal that is connected to the LED, provided in either 2, 4, or 8 colors. The LED illuminates in a distinctive manner corresponding to the input signal.

Typically, a low voltage DC power supply is used to power the LED. The LED is connected to the power supply with two wires. One wire is connected to a positive voltage source and the other one is connected to a negative voltage source. The current flowing through the circuit controls the intensity of the LED. When an input signal is introduced to the circuit, it causes a change in the current flow and the change in the current flow results in a change in the light intensity of the LED. This is how the 2150QA1 indicator works to measure and display process variable values or alarm conditions.

When the LED is illuminated, the light output can be seen even in brightly lit surroundings. The LED display is also designed to provide user comfort and long life. The LED display features a wide viewing angle and an adjustable brightness level. Additionally, the display is designed for high endurance in order to withstand intense sunlight and harsh environmental conditions. Finally, the 2150QA1 LED display is also low on power consumption and long-lasting, making it an economical choice for process control instrumentation and machines.

In summary, 2150QA1 panel indicators make an excellent choice for processes where accurate indication of process variable values or alarm conditions is required. The LED display is designed for a wide viewing angle, adjustable brightness levels, low power consumption, and long life, assuring users of its reliability and cost-effectiveness.
