A smart relay is a compact, cost-effective device designed for simple automation tasks, offering basic logic control and timing functions. In contrast, a Programmable Logic Controller (PLC) is more robust and versatile, capable of handling complex automation processes, with advanced programming capabilities, higher processing power, and support for a wide range of inputs and outputs. While smart relays are suitable for small-scale applications, PLCs are used in more demanding industrial environments.
