A I\/O module<\/strong> (Input\/Output module) or I\/O Module (Input\/Output Module)<\/strong> is a hardware component for acquiring and outputting electrical signals. It serves as an interface between a measurement, control, or automation system and the connected sensors or actuators.<\/p>\n\n\n\n

Measurement values, switch states, or other process signals can be acquired through the inputs of an I\/O module. The outputs, on the other hand, allow control commands or signals to be sent to external devices such as relays, valves, motors, or warning systems.<\/p>\n\n\n\n

In the devices from the Delphin Message Series<\/strong> I\/O modules handle the connection of a wide variety of sensors and actuators and expand the functionality of the measurement and data acquisition system. Depending on the model, digital and analog inputs and outputs are available for a wide range of applications.<\/p>\n\n\n\n
