Inputs are signals or data received by the system, and outputs are signals or data sent from it. An input module detects the status of input signals such as push-buttons, switches, and temperature sensors. An output module controls devices such as relays, motor starters, and lights.
The most common type of PLC I/O is discrete I/O, also referred to as digital input and output. Digital I/O units serve as the PLC's interface to achieve fast, reliable sequence control.
Other types of specialty input and output devices are used for motion control, temperature control, load cell inputs, safety systems and various communication protocols.
How do I pick the right I/O?
High density I/O units can help improve machine efficiency, streamline your manufacturing operation, reduce complexity and enable IIoT & Industry 4.0.
Advanced I/O technology gives operators enhanced capability for preventive and predictive maintenance, visibility into costly and dangerous errors and a comprehensive coverage of data points. Users can see what the sensor is doing and how well it is performing at all times, and can quickly spot and identify a problem without shutting down the line or machine.
