We have a line that uses a bunch of tri color led indicators. They
are listed to work with voltages of 12-24 VDC.
They fail within hours to a few months. Since the system runs at
24VDC, I figured putting a 820 ohm resistor to drop the voltage to
about 15 vdc when illuminated would fix everything. Well it does not
seem to be so.
FWIW, the indicator is a P+F LED18-RYG-P.
Any ideas on what might be killing these things or how to protect
them. All the other components of the systems (plc's, motion systems,
sensors) are working fine and not failing on us.
Thanks,
Wes
