What Is Discrete IO?
Discrete IO refers to input and output modules that are used to process digital signals, typically to monitor and control the on/off state of a device. Discrete signals have only two states: on (1) or off (0), for example, push buttons are pressed and released, relays are turned on and off, and so on. Discrete IOs are widely used in industrial automation systems to input signals from field devices (e.g. sensors, switches, relays, etc.) to the control system, or to transmit output signals from the control system to the field devices to realize real-time device control and status monitoring.
