To ensure that the PLC's fast millisecond output is accurate and will operate the cleaning cycle of the bag filters, I built this PCB.
I would appreciate it if you could let me know if this inspired you to test your system.
I felt compelled to do that even though my client didn't ask for it.
The circuit generates square pulses that travel through the PLC output relay contacts to be captured by counters. The counter's value is displayed on 7 segment LED digits.
Despite being built more than 20 years ago and had been tossed around for years, this circuit is still working today.
