Analog I/O

Analog inputs allow the PLC to read variable values from sensors, such as temperature, pressure, or flow, by converting physical measurements into electrical signals, typically in the form of voltage (e.g., 0-10V) or current (e.g., 4-20mA). Conversely, analog outputs enable the PLC to control devices like motors, valves, or actuators by sending continuous electrical signals to adjust their operation with precision. These I/O channels are crucial for processes that require more than simple on/off control, providing fine-tuned adjustments to optimize performance in dynamic environments. Analog I/O API provides interface for controlling all analog inputs and outputs on your controller.
