B&R AO352 7AO352.70 Analog Output Module
The B&R AO352 is an analog output module used to output continuous analog signals from a B&R control system to field devices. Modules with this designation interface the controller with analog actuators and signal devices, converting the system's digital values into analog voltage or current outputs for proportional control of valves, drives, indicators and other analog loads.
