Most people in the electrical industry know what a time relay is. It is a very popular and well-known equipment in the energy market. Since 1968, time relays have been known for their reliable design, long life and low maintenance costs. timing realys have effective working principles and can select functions and delay ranges to ensure that you receive the perfect timing relays to meet your needs.
What is a timing relay?
timing realys periodically change the state of their contacts when their coils are energized. Typically, contacts remain closed or open for periods ranging from milliseconds to hundreds of hours from externally adjustable. The number and cycle of control contacts depend on the timer design.

How does the timing realy work?
timing realys work as follows:
First, a supply voltage is applied to the timing realy.
Next, the microprocessor starts up.
Next, the microprocessor reads the information from the interface. This interface includes different adjustment possibilities in front of the timer. The fine-tuning time function, time range and required delay time must be set by rotating switches and potentiometers.
In the fourth step, the microprocessor reads information about control inputs, such as those used for startup delays. The information from this timer is used to start the action, called the "start pulse" or "trigger."
Now the timer is working.
The selected delay is complete and the output relay is powered on/off.
When the output relay is excited, the load current acts as a contractor to supply power to the connected equipment.
Application of timing realy
timing realys are suitable for a wide range of applications including:
Machine: single machine, star triangle motor start, industrial automation, process flow
Construction: lighting control, automatic doors, parking lot guardrail, rolling curtains
Water: pump control and irrigation system
Hvac: fan and central water supply system
Other application examples:
Mechanical cycle switches, for example, start fans weekly to prevent clogging or flushing pipes and keep pipes clean.
Lighting controls, for example, multi-row light delay switches in production facilities or greenhouses.
Control of starting or closing time of mechanical equipment, such as delayed closing of the conveyor belt or continuous closing of the plant.
Trigger an alarm in the event of fault detection, such as industrial applications or flashing lights on rail vehicles.
Taking the star triangle motor as an example, the starting current and switch delay can be reduced to prevent interface short circuits.
For example, when you press a button in a crosswalk, when you press the button on the walk signal, after some time the light changes from "never walk" to "walk."
