An analog timer is also called time relays. The advantage of an analog timer is that the setting time can be easily adjusted with a dial, but on the other hand, there is a risk of error due to the analog type.
An analog timer can not only be switched ON/OFF only once, but can also be turned ON/OFF periodically, or the input/output values can be changed, such as turning the output ON or OFF upon receiving an ON input.
Analog timers can be used to run a device or stop a device after a certain amount of time has elapsed. Analog timers are classified according to several modes of operation, which should be selected according to the timing at which you want to switch outputs.
Below are some examples of analog timers in use:
Analog timers consist of four parts: a clock section, a power supply section, an input section, and an output section. In the case of a power start method, the analog timers are activated after the voltage is applied to the power supply section. The input section receives input signals from the outside, the clock section measures the time, and when the set time is reached, the output section sends out an output signal to the outside. The user can set the set time as desired. When the set time is reached, it is called time up.
There are several types of analog timers operation modes.
ON/OFF switching is performed by switching contacts. The fifth type, "star-delta operation," is difficult to visualize from its name alone, so we will briefly introduce it here. Star and delta are named after the circuit shape of the motor winding, and the timer is controlled by turning the star/delta contacts ON and OFF.
