Where are time delay relays used?

Timing Relays are used extensively in industrial applications, HVAC systems and building services to provide time-delayed switching. For example to start a motor, control an electrical load, or simply automate an action. They play a vital role for targeted logic needs.

What are the type of time delay relay contacts?

The type of time delay relay used will depend on the system setup. On- and off-delay timers represent the most typical time delay relay timers in use. Other types include interval-on-operate, flasher, and repeat cycle timers. Normally open, on-delay timers start timing when the input voltage (power) is applied.

What is difference between on delay and off delay timer?

In On Delay Timer -After The Input Is Turned On There Is A Delay Before The Output Is Turned On. In Off Delay Timer —After The Input Is Turned Off There Is A Delay Before The Output Is Turned Off. To put it simply, ON delay timer turns on a circuit after a predetermined time has elapsed.

What are the primary types of timing relays?

On- and off-delay timers represent the most typical time delay relay timers in use. Other types include interval-on-operate, flasher, and repeat cycle timers. Normally open, on-delay timers start timing when the input voltage (power) is applied.

How many types of timers are there?

Timers can be categorized into two main types. A timer that counts upwards from zero for measuring elapsed time is often called a stopwatch, while a device which counts down from a specified time interval is more usually called a timer. A simple example of this type is an hourglass.

What is the basic difference between TOF and TON timer?

A TON is a timer on delay and a TOF is a timer off delay. Both have EN bit, DN bit,TT bit. They both time to a preset. The differents between the two is TON times to on and the TOF times to off.
