Panel Indicators, Pilot Lights

1051C4 is a four light sequence panel indicator which provides a visual, in-panel indication of the operating status of a process. It combines 4 indicator lights together, each with its own label as to it’s indication or operation.

Application Field

The 1051C4 is most commonly used in automation and machine control systems, industrial and manufacturing processes, and other applications of similar nature. It can provide a powerful visual indicator when it is necessary to display the status of a process or system with more than a single set of lights.

Working Principle

The 1051C4 indicator light uses a simple electrical circuit that consists of a series of resistors and transistors. Each resistor and transistor is connected to one of the four individual LED indicator lights, each of which is activated when the appropriate voltage is applied to the circuit. The circuit is designed so that when one light is activated, the others are not activated.

The voltage applied to each circuit is determined by a control device such as a panel switch or PLC input. When the switch or PLC input is closed, it supplies the necessary voltage to the appropriate circuit, thus activating one of the four indicator lights.

Therefore, the 1051C4 indicator light can be used to provide a visual indication of the status of a process or system. It is a very reliable and effective way of conveying information, and can be used in a variety of different applications.
