What is a time relay
A time relay is a device that uses an electromagnet to control the flow of power in a circuit. The device includes a coil wound around an iron core. When current flows through a circuit, it creates a magnetic field in the electromagnet.
Timer Relay Application
Timer relays are suitable for a wide range of applications including:
Machines: stand-alone, star-delta motor starting, industrial automation and processes
Buildings: Lighting Controls, Automatic Doors, Parking Barriers, Roller Shutters
Water Section: Pump Control and Irrigation System
HVAC: Fans and Centralized Water Systems
How do timer relays work?
The working principle of the timing relay is as follows:
First, apply the supply voltage to the timer relay.
Second, the microprocessor starts to boot.
Next, the microprocessor reads the information from the interface. The interface consists of different adjustment possibilities on the front of the timer. The time function, time range and fine-tuning of the desired delay time must be set via rotary switches and potentiometers.
In the fourth step, the microprocessor reads the information of the control input, such as the control input used to start the delay. This information from the timer is used to start the action and is called the "start pulse" or "trigger".
Now the timer starts working.
When the selected time delay is complete, the output relay energizes/de-energizes.
When the output relay is energized, the load current acts like a contactor to power the connected equipment.
