Digital Input Module

 an input module is something where the input device is connected to the panel or a sensor or to a Programmable logic controller. It works as a device communication to control the work process, its timing and the status reporting. An input module worked as to connect and flow the data between the processor and memory which are the internal devices and to the external devices.

This Digital Input module is usually permit a microcontroller to perceive logic states and to work according to its logic. In a literal level, Digital input module comprehend digital input and output module for the work of automation. This modules are actually connected to the automation work through many sensors and actuators. The Digital input module borders  with up to four component things like electric, gas meters or many digital inputs. It is a indicator from sensors or other paraphernalia also in plant.
