Relays should be adjusted from approximately three seconds to thirty minutes with high precision. Being able to vary according to the type of actuation, they can get a delay in the energization, which basically refers to the operation of their keys in a period after their connection, returning them to rest after their shutdown or de-energization. The deenergizing delay acts with the keys at the time of activation, so the keys should only return to sleep after deactivation. The button used to select the delay time is installed on the relay panel.
In this way, relays feature a highly efficient digital electronics, which allows high accuracy, repeatability and immunity to different types of noise that may occur. Designed according to international standards, reles enable a compact and safe solution in boxes with reduced dimensions for rail mounting. Reliable timers are treated in electronic devices which, depending on the set times, cause an output signal to be switched according to its specific function. They are widely used in automation of machines and industrial applications, such as starter motors, control panels and industrial furnaces.
