Panel Indicators - C905-NWO2-O

Introduction

C905-NWO2-O is a kind of panel indicator designed by EVERLIGHT. It includes two different types, which are Type A,Type B. The products of the two types are matched with an LED or a Neon Tube to indicate the working status of a device. Type A is a pre-assembled panel indicator suitable to be used in most applications. Type B offers customers the option of panel organization.

Application field

C905-NWO2-O can be widely applied in a variety of fields like machinery, automatization, metallurgy, electricity, food and beverage, medical treatment, chemicals etc. It is ideal for use in car, boat, or even a caravan, providing visual indication of the device’s status.

Working principle

The C905-NWO2-O panel indicators can generally be divided into two structure types: The Lamp Type and the LED Type.

• Lamp type: This panel indicator includes two types of Neon lamp, one is the low current Neon lamp(CWNE), the other is high current Neon lamp(TCBE-A). The CWNE is conveniently used for detectingthe voltage via an extra current limiting resistor. The TCBE-A is applied for making certain outputs for power panel.

• LED type: This panel indicator has three kinds of LED. They are red, yellow and green. The red LED lights up when the electrical circuit is on , while the green LED will be illuminated in case of the electrical product is off. Besides, the yellow LED stands for caution signal. All the LEDs need a driver circuit to work.

Conclusion

The C905-NWO2-O panel indicators play an important role in a variety of fields. Types A and B serve different purposes; even the same type offers multiple LED options. The working principle of the panel indicator is relatively simple. It supplies visual indication of the device’s status by different LEDs.
