464-ALP28H-NYO

Panel indicators are essential components in towercabs, switchgear, annunciator panels, and other electrical control systems. Pilot lights are subcomponents of indicators and are primarily used for signal indication. 464-ALP28H-NYO is an example of a panel indicator and pilot light combination, providing users with reliable indicating and signaling capabilities in a single unit. In this section, we discuss the application field and working principle of 464-ALP28H-NYO.

Field of Application:

464-ALP28H-NYO is a panel indicator and pilot light combination unit designed for control panel illumination and signal indication in harsh electric environments. This unit is ideal for demanding applications such as those found in power generation and instrument control systems, where dependability and long-term operation are a necessity. This unit is especially reliable in damp and wet areas that are time dependent, meaning it can make it through rainy conditions unscathed.

Aside from its ability to handle harsh environments, 464-ALP28H-NYO also has high resistance to vibration, shock, and dust. Additionally, this highly durable unit is also able to withstand temperatures from -55°C to +85°C, making it suitable for nearly any application. Furthermore, the 464-ALP28H-NYO includes an internally-operated socket, meaning users can simple plug-in and mount the unit for immediate operation.

Working Principle:

464-ALP28H-NYO operates on a bi-stable switching principle. This means that this unit will maintain a stable state under all conditions of input control until a new instruction is given. This allows the unit to remain in its current state until it is instructed to switch, preventing unintentional switching and reducing the likelihood of unexpected shutdowns.

To switch this unit, users can employ a variety of methods. This unit can be switched manually or through an electrically-controlled potential. Additionally, 464-ALP28H-NYO can also be used with manually operated switches, motors, transistors, and more. Furthermore, to obtain reliable signal indication or control panel illumination, users can employ either a motor or a vane actuator to switch this unit.

For motor-operated switching, 464-ALP28H-NYO is supplied with a high-power contactor. This contactor will instantly switch the unit in either direction and reset itself when released or touch back down. Furthermore, for more reliable sound signalling, users can connect a loudspeaker or bell directly.

Furthermore, to enhance signal indication, 464-ALP28H-NYO also features an incandescent bulb that can be used to indicate pilot light functions of the unit. This incandescent bulb is rated for a maximum Permissible Continuous Current of 350 mA, meaning it can be used in even the harshest environments without compromising performance or safety.

In conclusion, 464-ALP28H-NYO is an ideal solution for demanding environments. This panel indicator, pilot light combination unit offers users dependable indicating and signaling capabilities in a single unit, while its high resistance to vibration, shock, and dust its ability to withstand temperatures from -55°C to +85°C makes it suitable for nearly any application.
