Understanding Discrete Input Modules in Automation
What Are Discrete Inputs?
Discrete inputs are digital signals that represent two possible states: ON or OFF, TRUE or FALSE, HIGH or LOW. These signals originate from field devices and are transmitted to the control system for processing. Common examples include emergency stop buttons, proximity sensors, and pressure switches.
Role in Control Systems
Discrete input modules act as the interface between physical devices and the central control processor. They receive electrical signals, condition them, and convert them into readable digital data. This data is then used to trigger actions, generate alarms, or control machinery sequences.
