Answer Posted / kj
A relay is designed to act on one type of input signal
only. It may have adjustments for a range but can only
perform one function.
A PLC (programmable Logic Controller) can be made to
perform many differnt functions including the functions of
relays. this is done by selecting the type of inputs and
outputs required when buying and then programming to suit
the functions wanted.
