5 Questions
Match the following relay parts with their descriptions:
Primary circuit = Provides the control signal to operate the relay Secondary circuit = Connected to the load being controlled Time delay relay = Control relay with a time delay function built in Relay = An electrically operated switch using an electromagnet or electronics
Match the following relay applications with their descriptions:
Industrial applications = Extensive use in industrial settings for time-delayed switching HVAC systems = Utilized for time-delayed switching in heating, ventilation, and air conditioning systems Building services = Provide time-delayed switching for various building automation actions Automate an action = Usage to start a motor, control an electrical load, or automate specific actions
Match the following relay types with their operation method:
Traditional relay = Uses an electromagnet to mechanically operate the switch Solid-state relay = Operates using electronics instead of an electromagnet Time delay relay = Control event by energizing the secondary circuit after a certain amount of time or for a certain amount of time General-purpose relay = Available as single-function, single time range devices traditionally, but now have advanced functions and time ranges
Match the following relay descriptions with their definitions:
Time delay relay = Simply control relays with a time delay function built in Relay = An electrically operated switch traditionally using an electromagnet to mechanically operate the switch Primary circuit = Provides the control signal to operate the relay, connected to a low voltage DC supplier Secondary circuit = Connected to the load which is being controlled, such as a fan, pump, compressor, or light bulb
Match the following relay components with their typical usage:
Plug-in devices = Where time delay relays can be found in variety of applications Circuit boards = Common location for advanced function and advanced time range time delay relays Thermostat = Example of a device that could control the primary circuit of a relay Manual switch = Another type of sensor that could control the primary circuit of a relay
