The ABB FET321-1C0A1A1C1 is an external measuring transducer for magnetic-inductive flow meters of the ProcessMaster 300 and HygienicMaster 300 series for separate installation from the flow sensor. The device processes the measurement signals from the transducer and provides a current output of 4–20 mA with HART communication as well as configurable pulse and switching outputs. The graphic LCD and the local control panel enable the display of process values, parameterization and the display of diagnostic messages. The digital input supports external control functions including resetting and stopping the counters. The painted cast aluminum housing has a separate connection compartment and M20 × 1.5 cable glands. The transmitter operates on 100-230 V AC at 50 Hz and is intended for installation outside hazardous areas.
