VERVIEW
A M2000D weighing system consists of an indicator connected remotelly to one or two
DLC remote digital intelligent load cell terminal boxes, supporting up to 16 load cells.
A digital M2000D scale system provides for a high level of data integrity between the
scale platform and indicator for up to a 1000 feet apart. Because the analog scale data is
converted to digital data inside the remote DLC slave and send, as digital data to the
indicator, there is no data degradation across long cable runs. The digital system has a high
level of resistance to RFI /EMI interference, as required by industrial installations.
The M2000D system consists of an indicator and one or two DLC slave units. The DLC
slaves consist of 8 load cells per DLC. The digital system has no AD converters inside the
indicator itself. The M2000D supports 3 scale channels and calibration commands allow
the user to assign any or all of the load cells on the DLCs to a particular scale. A scale
assignment might consist of either a hopper or sectional scale configuration. These hopper
/ sectional scale groupings are then allocated to the 3 scales provided for by the M2000D
indicator – see
Figure 1
for more detail.

configuration. The M2000 Digital indicator supports up to 16 load cells.
q
The system allows for a combination of hopper type and /or sectional scale allocations
q
A DLC slave can be up to a 1000 feet from the indicator with no data degradation
q
Each load cell converter has a programmable input range of 10,20,40 or 80mV
