PEF3006 Process Control. USN. F. Haugen. 2017 Process Controller (ECA600, ABB) PEF3006 Process Control. USN. F. Haugen. 2017

Process Controller cont. Digital communication Backplane of ECA600: AO = Analog Output (from controller) = Control signal to the actuator AO signal ranges: 4 – 20 mA (most popular) or 0 – 5 V or 0 – 10 V AI = Analog Input (to controller) = Measurement signal from the sensor AI signal ranges: 4 – 20 mA (most popular) or 0 – 5 V or 0 – 10 V PEF3006 Process Control.
