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.

Applications

•t 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.
•t 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.
•t 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.
