A rather rare indicator.
IEL indicators are luminescent capacitors. They need to be powered
with a voltage of about 250V and
a frequency of 0.4-1 kHz. The current through the segment is 0.1 – 0.5 mA. The control is built using resistor optocouplers. You can also use any miniature relays. In
industrial devices, KU103V thyristors were used to control small IELS
. The service life of the indicator is about 500 hours. They glow very beautifully in the dark. You can output symbols not only in the form of Arabic numerals, but also in the form of alien counter symbols from the Predator movie
