Panel Indicators, Pilot Lights, and 2191QU7-24V are all types of visual signals primarily used in industrial and commercial automation applications. UK-based Schneider Electric is one of the foremost manufacturers of these products. The company’s 2191QU7-24V is a voltage-controlled indicator light featuring an LED panel lamp that is designed to work with a variety of DC and AC voltage supplies. It is specifically engineered for quickly alerting maintenance personnel to voltage fluctuations.

Application Field of 2191QU7-24V

The primary application field for the 2191QU7-24V is electrical systems. It can be used as part of electronic equipment, circuit protection, and lighting systems in both commercial and industrial settings. It can also be installed in a variety of other electrical installations, such as vehicle, appliance, or machine control systems. Additionally, due to its high reliability, it can also be used in safety systems, such as emergency lighting, exit signs, and explosion-proof equipment.

Working Principle of 2191QU7-24V

The 2191QU7-24V is designed for quickly sensing and then indicating changes in supplied voltage. Its inner workings are based on a EIC network, which is a series circuit comprised of several elements designed to provide a wide range of currents, resistances, and cutoff voltages. In the case of the 2191QU7-24V, the network is made up of an LED panel lamp, EIC, resistor, IC, and a few other components, all of which work together to detect and indicate changes in voltage. When a pre-set voltage is reached, the current through the LED panel lamp is cutoff instantly, causing it to flash and immediately alert personnel to the change in voltage.

The 2191QU7-24V is an outstanding example of advanced engineering and design. It is designed to operate reliably at DC and AC voltages between 12V and 24V, making it ideal for a wide variety of applications. Its built-in over-voltage protection further enhances its safety and reliability. Additionally, its extremely low-energy consumption ensures its continued operation even in locations without access to a continuous power supply. The 2191QU7-24V is a highly reliable, low-cost, and efficient solution for instantly indicating changes in voltage.
