Panel Indicators, Pilot Lights

32R-2217T indicator is widely used in industrial control panel. It includes a two-color LED light source, aluminum stone design, wide angle viewing angle, wide application voltage range and long life. It can be applied to the front panel of industrial system for fault indication, signal indication, instruction prompting and other functions. When the switch is opened or closed, the bicolor LED indicator will change the color and provide the application feedback.

Working principle of 32R-2217T

The 32R-2217T indicator consists of two light emitting diodes, one red and one green. The light emitting diodes are embedded in a single package of aluminum alloy. The light from the two diodes is combined into a single beam while travelling through the orifice of the indicator to exit as one mixed color beam. When the switch is opened or closed, the different color light is emitted from the two diodes, thus changing the color of the emitted light beam.

The indicator works on a basic principle of diode circuit voltage drop. When a voltage is applied to the circuit, current flows through the diodes and drops some of it across the diodes. The voltage drop across the two diodes depends on their wattage and the resistance of the circuit. The lower wattage diodes will drop lower voltage across it and thus the greater amount of current will be directed through it, resulting in a brighter light.

This indicator operates with a nominal voltage of 12Vdc. When the application voltage is greater than 12Vdc, the current passing through the two diodes is increased, resulting in a brighter light. Conversely, when the application voltage falls below 12Vdc, the current passing through the two diodes is decreased and the light emitted by them is dimmed.

Applications of 32R-2217T

The 32R-2217T indicator is a flexible and cost-effective solution for industrial applications. It is typically used as an identification light in control panels and machine safety systems. It is also used as fault indication in process control and instrumentation systems. Since it is designed with an aluminum alloy housing, it is suitable for operation in harsh environments where it is exposed to extreme temperatures, dust and vibrations.

It can also be used in outdoor lighting applications as it is designed for wide temperature range and high humidity making it ideal for outdoor applications. Additionally, with its wide operating voltage range of 12Vdc to 32Vdc and long-life, it is suitable for many complex applications.

The 32R-2217T indicator is widely used in Industrial automation systems, machine Interlocking systems, manufacturing equipment, emergency lighting systems and many other critical applications.
