ABB D674A906U01
The ABB D674A906U01 module is an electronic module designed by ABB for its FET300 series electromagnetic flowmeters. It is the core part of the flow meter, which is responsible for receiving the electromagnetic induction signal generated by the flow sensor and converting it into a readable flow value.
Main function
Signal processing: The weak electromagnetic induction signal generated by the flow sensor is amplified, filtered and digitized.
Flow calculation: According to the processed signal, combined with the known parameters of the flow meter, calculate the actual flow value.
Signal conversion: The calculated flow value is converted into a standard analog signal (such as 4-20mA) or a digital signal (such as HART protocol) for easy connection with other instruments or control systems.
Temperature compensation: Considering the influence of temperature on the measurement results, the module has a temperature compensation function to improve the measurement accuracy.
Self-diagnosis: The module has a self-diagnosis function, which can monitor its own working status and issue a fault alarm.
Parameter configuration: Through the HART protocol or other ways, you can configure the parameters o
f the module, such as range, unit, output mode, etc.
Product parameters and specifications (typical values, refer to the product data manual)
