The Fisher part number 01984-4080-0001 refers to a main electronic printed circuit board (PCB) assembly or a central processing module used in Fisher FIELDVUE digital valve controllers (likely for the DVC6000 or DVC2000 series). This component is the "brain" of the positioner, containing the microprocessor, memory, communication chips, and input/output signal conditioning circuits. It is responsible for executing all the core functions of the device, including interpreting the 4-20 mA input signal, calculating the required pneumatic output, driving the I/P converter, processing feedback from the travel sensor, running diagnostic algorithms, and managing HART or other digital communication.
