Time controllers are semi-finished modular electronic components from a circuit board and embedded electronic elements such as resistors, capacitors, relays, potentiometers or light and protection diodes, which are already assembled and configured. With the help of these regulatory modules, various timers, time relays with a variety of applications can be built. There are those that work on 230 VAC and 12 VDC and have multiple characteristics and parameters depending on the application for which they are needed.
Timers and time relays are an open, assembled kit without a housing with basic components that are ready to be installed. They give great choice and the ability to integrate into small or large projects. They can be designed as a standalone device or as part of another larger one to operate under certain conditions and as part of a larger electrical system based on automation in combination with other devices.
