As an OT shop, IT4Automation specialises in controllers and IOs. Controllers are essential system components, as they manage the entire process from start to finish. They act as the brains of an OT system by controlling how data is processed based on various inputs that can be configured. IOs, or input/outputs, enable communication between the controller and other components of an OT system. They receive information from sensors and valves, process it, and send signals to actuators to control energy flow through the system. By combining controllers with IOs, IT4 Automation ensures efficient and reliable operation of OT systems.
