Understanding Time Delay Relays

What is the primary function of a time delay relay in a circuit?

• To increase the voltage

• To amplify the signal

• To delay the operation of contacts

• To decrease the current

In a time on delay circuit, what happens to a normally open contact when the coil is energized?

• It closes after a set time

• It remains open

• It closes immediately

• It opens immediately

How does a normally closed contact behave in a time on delay circuit when the timer is counting?

• It closes immediately

• It opens after a set time

• It remains closed until the timer finishes

• It opens immediately

What occurs to the contacts in a time off delay circuit when the coil is energized?

• Open contacts close immediately

• Closed contacts open immediately

• Open contacts close after a delay

• All contacts remain unchanged

In a time off delay circuit, what happens when the power to the coil is cut?

• The contacts remain in their current state

• The contacts never change state

• The contacts change state immediately

• The contacts change state after a delay
