About the RMA803 Remote Indicator

The Honeywell RMA803 is a Foundation Fieldbus Remote Indicator that provides the following
benefits to the user:
Connectivity
The RMA803 can be used with any Foundation Fieldbus device. The values from these Fieldbus
devices can be connected to the RMA803 via the MAO function block (for example) and then sent
to the LCD display via the LCD Transducer block. The RMA803 can display up to eight (8) values
from the devices on the H1 segment.
Mounting
The RMA803 can be connected anywhere along the H1 segment, providing easy access to data from
devices that are mounted in inaccessible locations. The LCD module can be rotated in 90 degree
increments, allowing the RMA803 to be mounted in any orientation.
Capacity
The RMA803 can display up to eight (8) function block values. The RMA803 will automatically
rotate through these values at a user-configurable rate. The user can also step through the values on-
demand using the local pushbuttons.
LCD Display formats
The RMA803 provides three user-friendly formats, including bar graph and trend. The scale limits
of the bar graph and trend are configured by the user to allow optimum visibility of the process
value. The trend format will plot the trend of the selected function block value. The duration of the
trend is configured by the user, providing up to 24 hours of history for the selected value.
Custom labeling
The user can enter a custom tag for each screen to provide clear identification of the displayed value.
The user can also enter custom units for each screen, or select the units from a predefined list. The
length of the custom tag is 14 characters; the length of the custom units label is 8 characters.
Additional calculation and control
The RMA803 provides a robust set of function blocks that can be used to provide additional
calculation and control capability.
Backup Link Active Scheduler (LAS)
The RMA803 can also be configured as backup LAS, allowing the Fieldbus devices on the H1
segment to continue operating if the primary LAS fails.
