OMRON has taken the time to answer a few common questions relating to the use of timers in automation applications.
What is the difference between the Timer and the Time Switch?
The Timer controls the time from when the power is turned on or the input signal is supplied to when the operation starts. On the other hand, the Time Switch controls the time of day at which the operation starts with the power on.
Is there an ON/OFF repeat timer that lets you set the ON time and OFF time separately?
Use a Twin Timer, such as the H3CR-F, H5CX, or H3DE-F. The H5CX Digital Timer, in particular, lets you set the ON and OFF times without any setting error.
What are time-limit contacts?
Time-limit contacts operate according to a Timer's elapsed-time operation.
Note: The operation depends on the Timer model and operating mode. Check the timing chart (operating mode) for details.
