Concept:

  • In an automatic toaster system, a relay can indeed be considered a type of controller.
  • Relays are electromagnetic switches that can be used to control the flow of electrical current in response to a specific input signal or condition.
  • In the context of an automatic toaster, a relay can be used to control various functions, such as turning the heating elements on and off, timing the toasting process, and managing safety features like overheating protection.
  • The relay essentially acts as a control switch that responds to signals from the toaster's control system or user input.
