I need help with question 123 Explain the difference between

Explain the difference between the timed and instantaneous contacts of a mechanical timing relay. Draw the symbol and explain the operation of each of the following timed contacts of a mechanical timing relay: On-delay timer-NOTC contact On-delay timer- NCTO contact Off-delay timer-NOTO contact Off-delay timer-NCTC contact Name five pieces of information usually associated with a PLC timer instruction. When is the output of a programmed timer energized? What are the two methods commonly used to represent a timer instruction within a PLC\'s

Solution

Instantaneous contacts change state as soon a the timer coil is powered while the delayed contacts change their state at the end of the time delay.

This is the main difference between the timed and instantaneous contact of mechanical timing relay.
