Analogue Outputs - Endress+Hauser RMA 422 Mise En Service

Process transmitter

5.4 Analogue outputs

The following addresses are only available if the
unit is fitted with the analogue output option.
Parameter
* Reference value
Selection of signal source of
the analogue output value
* Output range
Select current or voltage
output with 0% and 100%
values.
* Scale
analogue output
Allocation of numeric display
value to the 0% analogue
output value.
*Scale
analogue output 100%
Allocation of numeric display
value to the 100% analogue
output value.
For inverted signal output the 100%value must be smaller than the 0% value
* Fault condition
Definition of the output signal
in fault condition. These are
sensor cable open circuit or
unit internal fault
* Simulation
voltage/current
Dependent whether current
or voltage output is set, a
number of values are offered
that can be transmitted to the
output
Once this address is left the output is automatically set to
The red LED flashes during active simulation!
