Quizplus · Accepted Answer

PLCs generally do not have a higher current capacity compared to conventional relay-type control systems. Instead, they are valued for their smaller size, lower cost, and higher reliability, among other benefits. Relays are designed to switch higher currents, whereas PLCs excel in control and automation tasks with lower current outputs, relying on external relays or contactors for high current applications.
