Product description
The D674A906U01 module is typically installed in ABB’s FET300 or ProcessMaster series flowmeters. It receives the measurement signal from the flow sensor, and after internal processing, converts the measurement result into a standard 4-20mA current signal or digital signal for communication with PLC, DCS and other control systems. The module also has a self-diagnosis function, which can monitor the working status of the module itself and provide fault alarm.
