sensor actor interface (SAI)

Sensor-actuator interfaces(SAI) are field devices in industrial automation that either acquire signals from sensors or provide control signals for actuators.

Sensor-actuator interfaces are located at the field level and are designed for the corresponding fieldbuses. Sensor-actuator interfaces form the interface between the sensor for the data of the measuring points or for the control data with which the actuators control the actuators.

Sensor-actuator interfaces can work wired or wireless; so with Bluetooth, ZigBee or other radio technologies.
