Design Notes
•
For simplicity, the proposed solution is not opto-isolated. Therefore, the input signals generator (could be a
PLC or other controller) must share the Ground with Everest CORE.
•
24 k
Ω
is not a random value. It is intended to fit the voltage-current characteristic curve of the Zener diodes.
•
Capacitors form a 1st order filter with the resistors. This will typically reject high-frequency noise coupled to
the wiring in most of the cases.
