Chapter 11, Problem 1RQ
What are the two basic classifications of timers?
Expert Solution & Answer
To determine
Identify the two basic classifications of timers.
Explanation of Solution
Timers are relays that operate after a specified time delay to fend off the malfunction of the motor.
Timers are classified into two types as follows:
- On-delay relay.
- Off-delay relay.
