Binay Opto Electronics Private Ltd. Manufactures LED Semaphore Indicator. Binay Opto Electronics Private Ltd. Binay Opto Electronics Private Ltd. Also offers LED based pilot lights, aviation obstruction lights, alarm lights, etc. LED Semaphore Indicator is a good reliable solid-state replacement for the conventional electromechanical semaphore indicator unit. In power distribution panels, LED Semaphore Indicators are normally provided to give a visual indication of the condition of a circuit. It consists of a rotating mechanical disc with inscribed pointers, which is actuated by relays. As it is an electromechanical device, the current consumption is high [100mA to 200mA]. Three input terminals are provided; common, red input, and green input. The unit`s current consumption is very minimal, at around 25mA. Finally, the LED Semaphore unit provides easier and greater visibility, since the LED rows are illuminated.
