I am looking for a 24 VDC pulse output chip/circuit, designed output 3 signals to the receiver; 1 Operating Normally, 2 Alarm sensed, 3 Alarm Resolved. Any pulse train different than these 3 forms will be interpreted as a communications failure by PLC.
I am looking to send this pulse to a low cost micro PLC with approx 14 inputs,
have it interpret the pulses and send an email alarm if pulse format 2 or 3 are received.
Something tells me the chip/circuit exists already.
Please advise, thanks. Mr. Green
