ANALOG
The analog output is only available on controller model DCR-1004. The
analog circuit comes standard with 4-20 mA, but may be configured for 0-20
mA. A hardware change will allow 0-5 V, or 0-10 V as the output.
The desired analog output should first be selected in mode 24. The two end
points must then be entered. For performing a distance to level measurement,
the zero point of distance will be at the transducer and the 4-20 limits will be
programmed in the same units as mode 1. For volumetric or open channel
monitoring, the zero point will be at the empty point of the tank or flume and
the end points must be set in the units used in the volume or flow measurement.
Keep this in mind when referring to the diagram below.
MODE DESCRIPTION PARAMETERS EXPLANATION
24 Analog Output Range = 0 - 1 Selects the type of analog output
Select 0 = 4 to 20mA output to be used
1 = 0 to 20mA Set by NUM UP or NUM DN
Default = 0
25 0,4 mA Distance Units = mode 1 Sets the minimum distance of
Default = 3.00 ft. the analog output slope
26 20 mA Distance Units = mode 1 Sets the maximum distance of
Default = 4.00 ft. the analog output slope
27 0,4 mA Calibration Fine tunes the minimum current
sourced on the analog output
28 20 mA Calibration Fine tunes the maximum current
sourced on the analog output
