P81W-A48H-CA

P81W-A48H-CA is a type of panel indicators, pilot lights. These devices use LED and incandescent bulbs to provide on/off status indication in a wide variety of applications from machine, industrial equipment to HVAC systems. These devices are particularly suited to control applications and provide assurance of operation.

The panel indicator will usually be supplied from an electrical panel using a separate power source. This power source will usually be a transformer, which can be set up to provide a single phase or multiple phases of power. Depending on the model, the power will either be collected via a Power over Ethernet (PoE) or hard-wired connection.

The P81W-A48H-CA consists of a printed circuit board, a control panel with an input terminal, output terminals, and two indicator lamps. The control panel is generally used to select which of the input terminals provide the current to the indicator lamps. This allows the user to select which terminal\'s status to be indicated by the device.

The LED indicator will light when the voltage on the output terminal exceeds a predetermined value. This value is usually adjustable, allowing for precise control of the illuminated LED intensity. The incandescent lamp will be lit when the voltage on the output terminal exceeds a predetermined value.

The working principle of the P81W-A48H-CA is quite simple. The current from the power source is fed to the input terminal. This is then routed to the output terminals. If the voltage on the output terminals is higher than the predetermined value, the LEDs will light and the incandescent bulb will be lit.

The P81W-A48H-CA panel indicator is a reliable and cost-effective solution for providing status indication in a wide range of applications. It is easy to install and provides assurance that the device is operating correctly. Its ability to be adjusted to illumination preference makes it an ideal choice for any application where precise status indication is required.
