Strobe Light Failure Sensing
Strobe Light Failure Sensing
(OP)
I have some warning strobe light installed in a hazardous area and I need a way to sense if the light has failed and report it to the PLC. If the light has failed the equipment should not run. Any help would be greatly appreciated.

When the strobe fails, the monostable will fire or the oscillator will run.

One aside: If the application is something legally required like FAA tower lights, it is unlikely that a locally fabricated means would keep you out of trouble with respect to compliance.
