C46-BCR28H-CWO

Panel Indicators, Pilot Lights comprise a wide range of indicating electrical products intended for use in control and monitoring circuits. One of the most popular are the C46-BCR28H-CWO, a type of panel indicator. This article will discuss the applications and working principles of this device.

The C46-BCR28H-CWO is used to indicate the presence of electrical current or voltage. The device produces a flashing red light that offers a visual indication of 24 to 48 volts of AC or DC current or voltage being present. This is a unique feature when a standard indicator involves an LED where only a steady still light is available. The device can operate on 12, 24 or 48 volts.

C46-BCR28H-CWO is used in a variety of applications, primarily for alarming and monitoring. It is ideal for use as an indication light for a variety of commercial and industrial applications such as fire alarms, machine controls, access control systems, and alarm panels. It is also used in the automotive, marine and telecommunications industries. The device is designed to be low power and operates at a temperature range of -20°C to 70°C.

The device is relatively easy to install and requires a low level of maintenance. It is reliable and has LED life typically in the order of 100,000 hours. Its low energy consumption makes it ideal for applications where energy costs need to be kept under control. Furthermore, as the device is panel mountable, a single panel can accommodate multiple indicators.

C46-BCR28H-CWO features a unique opto-isolator design. This technology ensures that there is an electrical barrier between the panel and the indicator itself. This allows the device to function safely even in the presence of dangerous voltages, and also helps ensure a reliable communication data rate between the two components.

The working principle of the device is based on the interaction between an LED and a phototransistor. When current or voltage flows to the device, the LED emits a light that is detected by the phototransistor. This in turn triggers the flashing red light. As the phototransistor is reverse biased, the light is pulsed on and off. This alternating current then passes through a capacitor and a resistor before reaching the phototransistor again, thus allowing it to continue working.

C46-BCR28H-CWO is a reliable and cost-effective indicator light for many applications. Its opto-isolator design ensures safe operation and its low power consumption makes it an ideal choice for energy conscious projects. Furthermore, the device is easy to install and maintain, making it a popular choice among panel indicator, pilot lights.
