Double recycle time relay

Double recycle time relay

Sometimes we need to automate one electric - electronic element that makes continuous opening and closing his mark, like a flash, or something similar.
The double time doing just that.
It has, as shown in the photo, two positions for setting the time that the internal relay or transistor, is armed and the other adjust the time that the internal relay is deactivated.

Usually the range is independent for each time, e.g. may function to ON (armed) to select the region from 1 to 10 hours and for operation OFF (off) 0.1 to 1 second. In any case and for as long a duration is armed, the two times continuously rotated simultaneously with the contact.
The operating voltage of the double time is similar to that of other components used in automation. Common values ​​are 230 volts AC and 24 vollts AC or DC.
In the market there are times that can work in all standard voltages (the same) or multifunction time not only double but they and many other time functions.
The Timers that are more accurate but they are basically more expensive.
The numbers usually used for contact operation is 15 (for the common node) and 16/18 for open or closed contact, while arming them A1 and A2 (or B) depending on the manufacturer and the voltage operation.
