Data Sheet mA-Bus ConverterTM The MJK mA-Bus Converter™ is used when a measured value from a transmitter with analog mA signal is to be shown on an MJK display. The mA-Bus Converter™ translates any mA signal to Modbus® and can be used together with the MJK transmitter series for flow, dissolved oxygen, turbidity etc. There are two configurations of the mA-Bus converter. One is in the standard MJK field housing with blind lid, the other is in the MJK wide field housing with a display. The later configuration allows the converter from other MJK transmitters to be housed together with the mA-Bus converter. With the mA-Bus Converter™ the measured values are converted into Modbus values and displayed as engineering units. The large built-in data logger of the display unit offers 160,000 time-stamped entries. A trend curve of the loged data for the overview by the local operator is easily retrieved and shown in the display simply by pushing one button on the unit. The logged values can then be transferred as csv files to a PC. • The mA-Bus Converter™ is used for well water supply systems where the pipe system pressure is shown on the MagFlux® display together with the flow. • For booster stations on the water supply system, where a pressure transmitter measures and controls the speed of the pumps and the pressure is shown together with the flow and volume of the water flow. Add the pump’s power consumption if needed and a complete system data viewing and collection is possible. • Another example is to measure dissolved oxygen in aeration basins and add a Redox potential (ORP) measurement from a transmitter with mA output for side by side display and data logging.
