Hey All
Regarding suppression of inductive voltage spikes for PLC outputs, I am after some practical guide for making the following decisions:
1) If the output does not have any suppression provided, what is the disadvantage of providing suppression at the PLC output terminals versus at the field device? In some cases (i.e. encapsulated solenoids) it can be difficult to provide suppression at the solenoid.
2) What are the advantages of RC snubbers vs flyback diodes for DC applications?
Thanks.
