with an ON delay timer once the power has been appied to the timer unit, the timer contacts will change state-open/close after a preset time (for example A&B timers are adjustable anywhere from 0.05 seconds to 300 Hours)
with a OFF delay these contacts change state after the power to the unit has been removed then the preset time will time out (this count dosen't start until the power is removed
What else can I help you with?
What is the difference between on delay timer and off delay timer?
The difference is that one is on and the other is off.
Draw the symbol for On delay times contacts and Off delay timer contacts and explain how each operates?
symbol of on delay timer
How does an off delay timer work?
when off delay timer gets control signal, its NO(NORMALLY OPEN) contact become NC(NORMALLY CLOSED) for preset duration, and then become NO.
Why is a timer is used in an electrical circuit?
Timer relays are used in control circuitry. There are two main types, an (off delay) and an (on delay). If you want one device to turn off before the timer controlled device then you would use an off delay timer. If you want one device to turn on before the timer controlled device then you would use an on delay timer. When the timer is energized this starts the timer circuit in the relay to time out.
Why timer can be used in star delta starter?

What is a timer relay?
A timer relay is an electromechanical or solid-state device that controls a circuit based on a preset time interval. It combines the functionality of a relay and a timer, allowing it to open or close contacts after a specific delay or during a timed sequence. Timer relays are commonly used in automation systems, industrial controls, and various applications where timing is essential for switching operations. They can be adjusted for different time settings and modes, such as on-delay, off-delay, or interval timing.
What is a digital delay box used for?
delay box is a term in drag racing to describe an on board timer which is a transmission brake delay timer which forces the race car to remain stationary at the starting line.
The timer file for SLC 500 controller is what?
The timer file for an SLC 500 controller is a data structure used to manage timing functions within the programmable logic controller (PLC). It contains information about various timer instructions, such as TON (timer on delay), TOF (timer off delay), and RTO (retentive timer on), along with their settings and status. This file helps track elapsed time and control operations based on specific timing conditions in automation processes.
Does this breadmaker have a delay timer so you can set it the night before?
The breadmaker has a 13 hour delay timer so you can set the machine the night before and have fresh bread in the morning.
Hoover washing machine - NextraOptima what does a red flashing light on start-delay start mean Is it pump gone?
A red flashing light on the Hoover Nextra Optima washing machine when the start delay timer is set might mean that the timer itself is not operational. Run the washer on the regular cycle, and if it works fine, it is the delay timer.
Why is your lights staying on when your keys are out?
It could be two things your switch for the lights is still turned on or your lights are on a timer and shut off after a twenty second or so delay.
What is the timer count needed to create a time delay of 100 ms if the timer clock frequency is 1MHz?
100ms=.1 1Mhz=1000000 .100x1000000=100K timer count
