If you mean in a simple applications the answer will be yes but not economic and if you mean in a big applications then the question will not make a logic , It is look like saying can I use a donkey instead of a car !!!!
the main aim for the PLC optimize the hardware , yes sure you can do that .
RELAY IS USED JUST AS SWITCHING BUT THE PLC IS USED FOR LARGER APPLICATION OF RELAY LOGIC.
Of course. For large scale operations, PLC is more applicable. But for small scale operations, it is more cost efficient to use Relays.
Yes we can efficiently replace relays using plc
PLC can perform in different environments and it consumes small area for installation.
Also it can handle more number of operation at a time.
Actually P.L.C is replacement of relays.Which reduces complexity of circuits.If we use relays for big applications it will make things more complex
yes we can ; but we take in consideration the over all price and efficiency
Yes we can use but with some limitations. You can select and replace with I/O Modules depending upon existing Relay specifications.
Yes,PLC is modified form of Relays .relay controlled by manually and with PLC we control the process trough Programming
If you are using only for control then yes you can use but if you want to use for control and protection then not possible.
PLCs perform the same function as relays, but can do so much more. They can be put to great use when old relay panels need to be modernized, or when new systems need an elegant means of control.If the electrical control system has only a few inputs and outputs and the logic requirements are simple ON/OFF control, then relays can do the job just fine without a PLC. But if a dozen or more digital I/O are required (and maybe even some analog signals), then PLCs are the way to go. Each electrical device (input or output signal) is wired its own terminal point.
