Description
ABSTRACT
In most of the modern manufacturing and processing industries, there is complete industrial automation through sophisticated hardware and software like programmable logic controller (PLC), distributed control system (DCS), and supervisory control and data acquisition (SCADA). Microcontroller-based embedded systems play major role in industrial automation. One such widely used system is the programmable timer.
Depending upon the requirement of process, one can set the time of programmable timer. As the time period expires, the timer will either trigger or shut the process. Earlier there were mechanical timers that used gear assembly (same as wall clock) and mechanical contacts. But the problem with these was that due to mechanical parts and movements, they were not durable. Electronic timers have become very popular as these have more functionalities and long operating life.
The complete hardware circuit is divided into two sections—programmable timer main circuit and remote control transmitter and receiver units. The main circuit is a fully-functional standalone unit with front-panel control switch and LCD display. Remote control transmitter and receiver are add-on units. The receiver outputs are connected with respective control input pins of main circuit. Receiver output facilitates user to program and control timer operation using remote within 100-metre range.
