Analog output

The Rosemount 5600 has the possibility to handle two analog outputs which can be separately
configured.
However, if your transmitter is equipped with a primary 4-20 mA HART output, you must use Analog
Output 1. (Analog Output 1 is not available for primary output when using other bus communication
protocols than HART).

the specified upper and lower limits. As illustrated, if the source signal exceeds the Upper limit or falls
below the Lower limit, the output current is set according to the specified Alarm Mode settings.
If your transmitter is equipped with an optional analog output
(Analog Output 2), configure it as described above.

Select the source to control the analog output.
Enter the range values that correspond to the analog output values 4 and 20 mA. You
can specify any values as long as the Upper Range Value is above the Lower Range
Value. If the measured value goes beyond the measurement range, the transmitter
enters the alarm mode.
Choose the desired Alarm Mode. The Alarm Mode specifies the analog output state
when a measurement error occurs or when the measured value is out of range.
High: the output current is set to 22 mA.
Low: the output current is set to 3.8 mA.
Freeze Current: the output current is set to the present value at the time when the
error occurs.
Binary High: the output current is 4 mA under normal conditions. If there is a
measurement error, or when the source signal is out of range, the output current is set
to 20 mA.
Binary Low: the output current is 20 mA under normal conditions. If there is a
measurement error, or when the source signal is out of range, the output current is set
to 4 mA.
If the detected limit is out side the upper or lower limit, setting this parameter
suppresses the analog output from going into alarm mode.
